Honestly, most people assume Uxbridge is just a mirror of central London weather. It isn't. Not exactly.
Being right on the edge of the Metropolitan Line, tucked away in the Colne Valley, gives this place a slightly different vibe than the heat-soaked streets of Soho. You’ve probably noticed it if you’ve ever stepped off the train at the station: that extra little "bite" in the air during January or the way the fog seems to sit heavier over the Grand Union Canal than it does in the city.
The Reality of Winter in Uxbridge UK
Right now, in mid-January 2026, we’re dealing with what I call the "Grey Ceiling." It's basically been a cycle of damp and dim.
Today, Sunday the 18th, it's pretty much a standard winter day for us. We're looking at a high of 51°F and a low of 40°F. It's cloudy, somewhat gloomy, and the humidity is sitting high at 93%. You know that feeling where the air feels "heavy" even when it's not actually raining? That's Uxbridge today.
There's a light breeze coming from the east at about 6 mph, which doesn't sound like much, but when it’s 40 degrees at night, you definitely feel it.
The next few days? More of the same. Light rain is forecast for Monday, Tuesday, and Wednesday. Temperatures are going to hover around that 50°F mark during the day, dropping into the low 40s at night. Kinda predictable, really.
But here is where it gets interesting. Looking ahead toward the end of the month, things might actually get a bit "White." By January 25th and 26th, we’re seeing a chance of rain mixing with snow. Lows are expected to hit 34°F. Now, don't get your hopes up for a Winter Wonderland; usually, in this part of West London, snow is more of a slushy mess that disappears by noon, but it’s enough to make the morning commute a bit of a nightmare.
Why the Colne Valley Changes Things
Uxbridge sits in a bit of a geographical pocket. While the London "Urban Heat Island" effect keeps places like Westminster a few degrees warmer, Uxbridge is just far enough out to miss some of that protection.
The proximity to the River Colne and the various reservoirs means we get a lot more "low-level" moisture. This is why you’ll often see frost on the grass in Uxbridge when the pavements in Ealing are bone dry.
Annual Averages: A Quick Look
If you're planning a visit or just moved here, here's the basic breakdown of what the year looks like:
- Hottest Month: July (averages around 18°C/64°F, though we’ve seen spikes much higher).
- Coldest Month: January (averages around 5°C/41°F).
- Wettest Month: October (usually gets about 70mm of rain).
- Sunniest Month: June (roughly 7 hours of sunshine a day).
Honestly, the "best" time to be here is late June to early September. That’s when the climate is most comfortable for a walk through the Fassnidge Park or a pint by the canal.
Practical Survival Tips for the Uxbridge Climate
Since the weather is currently doing its "damp and grey" routine, here’s how to actually handle it:

- Layers are non-negotiable. The humidity makes the cold feel wetter. A thin base layer under a waterproof shell is better than one massive jumper that gets heavy if you get caught in the drizzle.
- Watch the wind direction. Notice how most of our wind this week is coming from the southeast or east? That’s usually colder, "continental" air. When it swings to the west, it’s milder but brings more rain from the Atlantic.
- The Canal path gets muddy. If you’re planning to walk from the town centre toward Denham, wear boots. The ground around the Grand Union doesn't dry out quickly in January.
- Prepare for the "Sun Peaks." Even in winter, when the clouds break for twenty minutes, the glare off the water and wet roads can be intense.
Basically, the weather in Uxbridge UK isn't out to get you; it's just very indecisive. One minute you're shielding your face from a northeast wind, and the next, you're peeling off a coat because the sun decided to make a five-minute appearance.
Check the forecast for next Sunday the 25th if you’re planning any travel—that's when the snow-rain mix is most likely to cause a bit of chaos on the roads. For now, keep the umbrella handy but maybe leave the heavy snow boots in the cupboard for another week.
