In brief: In today’s post we take a look back at the year in weather for 2025, which had few major stories. The notable exception was a winter storm back in January. There was also a hidden, but significant story as well. We also take a look ahead to a stand-out weekend and warmer weather for much of next week.

A look back at 2025

In some ways, last year was one of the quietest in recent history weather-wise for Houston. The most notable event occurred in January, with a hard freeze and widespread snowfall. Do you remember the snow? Many locations picked up 3 to 5 inches, and following this low temperatures dropped into the upper teens.

But after this January winter storm Houston’s weather turned tranquil. We made it through spring without major, widespread storms or flooding. All summer we experienced nary a tropical storm in the Gulf. Laughably, the only “threat” was conjured up on social media in July, when some non-meteorologists were energetically warning Houston that a hurricane was on the way. (It was not). Fall came and went with mostly calm weather as well, aside from a few tornadoes. Winter, to date, has been fairly mild. When you add it all up, it was a quiet year, especially after January. We see that in our website traffic. We average about 10 million page views a year on Space City Weather, and we were down by about 30 percent this year. I’m not complaining, I don’t like scary weather that threatens my home and family, either.

In one way, however, the weather in 2025 was extreme.

I am speaking about temperatures. I went ahead and plotted the average annual temperature in Houston dating back to 1969, when the official monitoring station was first moved to Bush Intercontinental Airport. It turns out this year’s average temperature of 73.0 degrees was the second hottest in the nearly six decades of records there. It was exceeded only by the mark of 73.1 degrees in 2024. In fact, the last three years have recorded the three hottest annual average temperatures at the airport since its opening in 1969.

One of the things that stands out on this graphic is that the annual average temperature in the 1970s was nearly five degrees lower. Now global temperatures have not risen that quickly, and it is not possible to say how much of the warming observed at Bush airport is due to climate change. Some is very likely due to urbanization around the airport. But a significant chunk is clearly due to a warming planet, as similar trends have occurred elsewhere, including Galveston Island. There is no question that Houston is quite a bit hotter now than it was half a century ago. Even a decade ago, for that matter. That is the hidden extreme from last year.

Friday

Speaking of heat, today will bring it. Highs will crest in the low 80s, maybe even mid-80s for some locations, thanks to a warm southerly flow ahead of our next front. Winds will be gusty, from the south up to 25 mph. The record high temperature for today is 81 degrees, and I’m fairly confident we’ll strike above that comfortably. In any case, we will be about 20 degrees warmer today than is customary for early January. The warmth will be goosed by mostly sunny skies. Lows tonight will only drop to about 60 degrees, before cooler and drier air arrives on Saturday morning.

Saturday and Sunday

The weekend won’t feel much like January typically feels in Houston, but it’s going to be gorgeous all the same. We should have wall-to-wall sunshine, and lower humidity. Saturday morning will be a bit windy, with northerly winds up to about 20 mph. But they should back down during the afternoon. Highs on Saturday will be in the upper 70s, with lows on Saturday night dropping to around 50 degrees. Sunday will be splendid and sunny, with highs around 70 degrees. We’ll have another night with lows around 50 degrees on Sunday night.

Next week

Much of next week looks warm for January as a ridge high pressure builds over the central United States. Monday probably will not reach the 80s, but most of the rest of the week will be in the vicinity. Skies will be mostly sunny during the daytime, and with dewpoints in the low 60s it will feel moderately humid. Nights will be mild. At some point a stronger front will push into the region later next week, probably late on Friday or Saturday. I don’t have much confidence yet in the details, but there could be a modest splash of rain with the front, perhaps on the order of one-half inch. For many parts of Houston there has not been significant rain in nearly four weeks, so anything would be welcome.

As for my runners, let’s hope that front makes it in time for the Houston Marathon on Sunday. I’m about 75 percent confident that it will, and we’ll have start-line temperatures in the upper 40s to lower 50s, with drier air. But there are risks. One is that the front is delayed, in which case we’ll be quite a bit warmer and muggier. Another is that the front comes through just before the run, and we see some lingering showers. Overall, I’m hopeful about race-day conditions, but not confident yet.

Have a wonderful weekend, everyone. I’m going to be outside a lot, soaking in this great weather.

In brief: In today’s post we discuss our transition from turbulent weather to a calmer vibe. We bring you tidings of a tranquil entry into the year 2026, a brief warm-up, and then a truly gorgeous weekend. Happy New Year, everyone!

New Year, calm vibe

Good morning, everyone. I hope you celebrate a safe and fun New Year’s Eve. In terms of weather, there’s not too much to worry about, which is a nice change from the high winds observed Monday (gusts to 40 mph and higher) and this morning’s light freeze across much of the region. Rather, we will see calm conditions today, tonight, and into the new year. Our mild and calm weather will persist into the middle of next week when things could turn a bit more turbulent. Given the tranquil conditions ahead, I feel comfortable in taking the New Year holiday off, so look for our next update on Friday morning. Happy New Year!

Wednesday

Temperatures this morning range from the upper 20s north of Houston, in typically cold areas like Conroe, to just above freezing in the urban parts of the city, and about 40 degrees right on the coast in Galveston. This will be our coldest morning for quite some time, and with winds turning west our temperatures will soon moderate. And it’s not just Texas that’s cold and dry, in the map below you can see that very low dewpoints prevail across the entire Lower 48 states this morning.

Of course it won’t last. With ample sunshine our temperatures today will climb into the mid-60s. For those out and about ringing in the new year, temperatures should fall into the upper 40s late this evening, but I don’t expect much in the way of a breeze to add additional chill to the air. Lows on Thursday morning will drop to around 40 degrees for most locations.

New Year’s Day

We start the new year with a fine, partly to mostly sunny day, with temperatures in the 70s. Dewpoints (and therefore humidity) will be rising, but they don’t look excessively high. Lows on Thursday night will only fall to around 60 degrees.

Friday

This is going to be a warm day as southwest winds really get going ahead of an advancing, albeit weak, front. We’re going to see gusty winds up to about 25 mph, and this influx of warmer air will push highs into the low-80s for much of the region. The record high for Houston, on January 2, is 81 degrees. I anticipate that we’re going to break that comfortably. However that front will eventually ride into Houston on Friday night, or early Saturday, to bring milder weather back into the picture. At this point I expect a dry passage.

Saturday and Sunday

The first weekend of 2026 looks like a real splendid one. Days will be sunny, and nights clear. Highs will likely be somewhere in the mid-70s with moderately dry air. Nights probably in the low 50s. Seriously, this will be fine weather for any outdoor activities you have planned.

Next week, and the Houston Marathon weekend

The first half of next week looks warm, with highs in the upper 70s to lower 80s, and nights in the 60s. So we probably will see the return of some fog (dreaded by most, but loved by some). We might see a weak front during the middle of the week, or maybe not. There is some slightly better agreement in the models that a stronger front will drop into the region around next Friday, Saturday, or Sunday. This front is likely to bring some rain with it (although at this far out, who can say for sure?) Anyway, the weather for Sunday, January 11th (marathon day) will depend on a) whether this front makes it, and b) when it does. A passage on Friday or Saturday morning would set up clear and cool conditions for Sunday. A passage on Saturday night or Sunday morning could mean rain and wind. For now I’d expect a passage before Sunday, but that is not something I am remotely comfortable predicting with confidence. More when we know something!

In brief: Houston is quite chilly this morning, and we’re dropping down another notch tonight. But following this we’ll be solidly on a warming trend heading into the new year. This weekend looks quite pleasant. Also, we take a peek at what weather might be like for the Houston Marathon.

Freeze line

Temperatures are comfortably above freezing this morning across the Houston metro area, but what about tonight? We are going to see ideal conditions for heat to radiate back into space this evening, including clear skies and light winds. This will bring a light freeze into the Houston region. My sense is that urbanized parts of Houston and coastal areas will remain just above 32 degrees, but that inland areas and outlying suburbs, such as Katy, probably will briefly freeze tonight. Essentially, if you experienced freezing conditions back on Dec. 15, there is a decent chance you will again tonight. These temperatures are not cold enough to affect pipes or anything like that, but do take care of sensitive plants and pets.

Tuesday

We are going to see solid sunshine today (and most of the week). This will allow highs to warm into the 50s today, with light northerly winds, before our chilly night tonight.

New Year’s Eve

After a cold start, expect highs in the mid-60s on Wednesday with sunny skies. Light winds will turn west, and then southwest over the course of the day and evening. We have no weather concerns for the New Year’s Eve holiday aside from chilly temperatures during the evening, likely dropping into the 40s by the time we ring in the new year.

New Year’s Day

With a southerly flow in place we’ll see a warmer day to start 2026, with highs in the lower 70s. As moisture levels creep up, we may see a few more clouds in the sky, although I expect plenty of sunshine. Lows on Thursday night will be warmer, perhaps dropping only into the lower 60s.

Friday, Saturday, and Sunday

Friday looks downright warm with highs in the lower 80s and sunshine. The weekend should be a bit cooler (although there is still some uncertainty here) as a modest front pushes down from the northwest. For now let’s go with highs in the 70s and lows in the 50s, with mostly sunny skies. Really, it looks to be like ideal weather for most outdoor activities.

Next week and the Houston Marathon

The first half of next week looks to be rather warm for January, with highs likely in the vicinity of the upper 70s and nights perhaps in the upper 50s. If you’ve been wondering about rain chances, those start to pick up around Wednesday or Thursday. That’s not to say rain is likely, but it does appear to be possible.

If you’re planning to run the Houston Half or Full Marathon, then you’re keenly interested in conditions for Sunday, January 11. I just completed my final long run early on Monday, so my body is (mostly) ready. What about the weather? I’m afraid the forecast is still pretty uncertain at this point. It’s possible that a weak-ish front arrives by Wednesday or Thursday of next week (bringing some rain), but depending on the timing of this front I think we might see a warming trend by Friday or Saturday. In that case we need another front to bring temperatures down for Sunday. This appears to be possible, although not certain.

My best guess is for low temperatures in the 50s on Sunday morning, with highs rising to the 60s. In terms of wind and rain, that is going to be depend heavily on whether we get that second front to drop temperatures for the marathon. In summary: there’s just not much clarity yet on running conditions. When there is, I will definitely let you know.

In brief: Houston is back to more classic December fare today, with low clouds, a gusty wind, and temps in the 40s. We’ll have a couple chilly nights tonight and tomorrow night before we make yet another run toward 80 by Friday. New Year’s plans look delightful, with no weather concerns at all right now.

Whew! It feels quite different outside this morning. Here’s a map of our 24-hour temperature changes.

This is our first morning in the 40s since December 20th. In that stretch, we’ve had 8 days in the 80s and 1 day near 80 (79° on Christmas Eve). Only 2012 and 2021 saw more 80-degree December days. We also set or tied 6 record highs in that stretch, hitting 84° on Sunday, our 2nd warmest December day on record. But that’s done for now. And so we discuss cool temperatures.

Today and Tuesday

That wind is going to remain with us most of this morning. By afternoon, it will begin to wind down, though it’ll remain a bit breezy. Gusts have been north of 50 mph at Hooks Airport in Tomball and in Galveston, 48 mph at Hobby, and 40 mph at Bush. Temperatures won’t go very far today. If the low clouds can clear out this afternoon, we’ll attempt to get into the low-50s as the models suggest. If the low clouds stay put, I may be apt to undercut model guidance and say we limp into the upper-40s at best.

Tonight will be cold, and there is a chance that a few spots get down around the freezing mark. It will probably just be the Conroes and isolated pockets in the Brazos Valleys of the world that get there thanks to a continued breeze and continued clouds. But either way, expect 30s away from the coast, a few low 30s north and west and 40 to low 40s at the coast. Tomorrow night will be a bit colder.

Tuesday looks splendid with sunshine developing. We should easily push into the 50s with lighter winds. Thanks to those clear skies and lighter winds, Tuesday night should be a bit colder than tonight.

Expect more 30s area-wide and a chance of a light freeze creeping closer than Conroe, perhaps in some of the more wooded areas in Montgomery, Liberty, and northern Harris Counties or isolated rural pockets of Fort Bend and Wharton Counties.

New Year’s Eve & New Year’s Day

We start to turn the corner Wednesday back upward into the 60s. Thursday may even push close to or past 70 degrees. For most NYE festivities on Wednesday, it looks great: Sunny and pleasant for the kiddos celebrating Noon Years and clear skies, light winds, and evening temps in the 50s, dropping into the 40s around or after Midnight. Enjoy!

Friday into the weekend

Temperatures should peak on Friday, as we’ll make yet another run toward 80 degrees. It’s probably notable that most of the area has not seen any appreciable rainfall since the beginning of December, which likely isn’t hurting these temps at all.

Whatever the case, the forecast trends a bit less confident beyond Friday, with some models indicating a bit of a small cool down, while others say Friday won’t be our last attempt to hit 80 degrees. Stay tuned.
