Honestly, looking out the window in Gloucester today, it’s exactly what you’d expect from January. Grey. Damp. Kinda relentless. If you’ve stepped outside near the Docks or tried to walk the dog along the Alney Island loops, you already know the vibe.
The current weather forecast Gloucester UK isn’t just about dodging a few drops of rain; it’s about a city that’s currently soaking wet from the inside out. We’ve just come off the back of Storm Goretti, which basically turned the local landscape into a giant sponge that can’t hold any more water.

Right now, as of Sunday, January 18, 2026, we're sitting at a chilly 43°F. There’s a persistent light rain falling, and the humidity is maxed out at 96%. It feels heavy. There’s a tiny bit of air moving—a 3 mph north wind—but it’s not enough to dry anything out.
What the next few days actually look like
If you’re planning your week, don't put the umbrella away. Sunday is topping out at 45°F with a low of 41°F. It’s that "soaking rain" that doesn’t look like much but gets into your bones.
Monday, January 19, sees things warming up slightly to 49°F, but the rain isn't going anywhere. We’re looking at a 20% chance of rain during the day, jumping to 40% at night.
Tuesday might be your only window of sanity. It’s still 49°F, but we’re expecting partly sunny intervals. If you need to do anything outdoors without getting drenched, Tuesday morning is your best bet. Just be warned: the wind picks up significantly here, hitting 16 mph from the southeast.
The midweek grind
- Wednesday, Jan 21: Back to the light rain. High of 47°F, low of 43°F.
- Thursday, Jan 22: More of the same. Light rain, 46°F.
- Friday, Jan 23: The temperature starts to dip again, hitting 39°F overnight.
The "S" Word: Is it actually going to snow?
This is what everyone asks as soon as the temperature drops. Looking at the long-range data for next weekend, things get interesting.
On Saturday, January 24, the forecast shifts from pure rain to a rain and snow mix at night. By Sunday and Monday (Jan 25-26), the rain clears out, but the "feels like" temperature is going to plummet. We’re talking lows of 32°F and even 29°F by the following Tuesday.
Basically, the dampness we’re feeling now is going to freeze solid by the middle of next week.
Why Gloucester weather is so weird
Gloucester isn't just "another UK city." We have the Severn. That river changes everything. Because we sit in the Severn Vale, the moisture just hangs here.
You’ve probably noticed the fog is thicker near the water, or that it feels five degrees colder at the Docks than it does up toward Abbeydale. That’s the maritime influence. Plus, the Severn Bore—while mostly a spring and autumn event—is heavily influenced by this kind of weather. Strong southwest winds can actually push the tide higher, which is why the Environment Agency currently has flood alerts active for the River Severn and River Leadon catchments.
The ground is saturated. That’s the phrase the Met Office keeps using. It means even a "light rain" can cause surface flooding because the water has nowhere left to go.

Tips for surviving the week
Don't trust the "light rain" label. In Gloucester, that usually means a fine mist that ruins your hair and soaks through "water-resistant" (but not waterproof) jackets in ten minutes.
- Check the River Levels: If you live near the Alney Island or Westgate area, keep an eye on the Environment Agency’s live maps. The combination of Storm Goretti’s leftover runoff and this week’s rain is keeping levels high.
- Layers for Tuesday: It looks sunny, but that 16 mph wind will make 49°F feel like 40°F.
- Prep for the Freeze: By next Sunday, the wet roads are going to turn into ice rinks. Get the grit ready.
The reality of the weather forecast Gloucester UK right now is a transition from "very wet" to "very cold." We’re moving out of the storm cycle and into a classic winter chill. Watch your footing on the towpaths, and maybe keep an extra pair of socks in the car. You’re gonna need ‘em.
