Honestly, if you've ever tried to plan a weekend in Gloucester during the middle of January, you know the drill. You check the app, it says "cloudy," and you think you're safe. Then you step outside and the wind off the Severn—or the Atlantic, depending on which Gloucester we're talking about—hits you like a physical wall.
Right now, the gloucester 10 day weather forecast is looking like a classic winter rollercoaster. We're seeing a shift from "mild but damp" to "actually quite freezing" as we move toward the end of the month.

The Current Situation: High Humidity and Low Visibility
Today, Saturday, January 17, 2026, it's mostly cloudy. The temperature is sitting at 41°F with a southeast wind barely moving at 3 mph. Humidity is high—92%—so that chill feels a lot deeper than the number suggests.
If you're heading out tonight, expect more of the same. The low is holding at 41°F, and it's going to stay cloudy.
What the Next Few Days Look Like
Tomorrow, Sunday, January 18, things get a bit messier. We’re looking at light rain all day and night. The high will be 45°F and the low 42°F. Basically, it's one of those "stay inside with a book" kind of days.
Monday is a weird one. The temperature actually jumps back up to a high of 49°F, but the chance of rain increases to 40%. It’s going to feel breezy with 7 mph winds coming from the south.
Mid-Week: The Wind Picks Up
By Tuesday and Wednesday, the "mild" part of the week starts to fade.

- Tuesday, Jan 20: Mostly cloudy, high of 49°F, but wind speeds jump to 13 mph.
- Wednesday, Jan 21: Light rain returns, high of 48°F, and the wind ramps up to 15 mph from the southeast.
That wind is the real story here. It’s going to make that 48 degrees feel significantly colder, especially if you're near the water or walking through the city center.
The Big Shift: When the Snow Arrives
Here is where the gloucester 10 day weather forecast gets interesting. Around Friday, January 23, the temperature starts to drop. We're looking at a high of 44°F and a low of 39°F.
Saturday, January 24, brings a mix of rain and snow. The high is 42°F, but the overnight low drops to 38°F.
By Sunday, January 25, we are firmly into winter territory. We're expecting snow showers during the day with a high of only 40°F. The overnight low is going to hit 33°F, which is the freezing mark.

The Deep Freeze: Late January Outlook
The end of this 10-day window is the coldest part of the month so far.
- Monday, Jan 26: Rain and snow mix continues, high of 37°F, low of 30°F.
- Tuesday, Jan 27: Partly sunny but very cold. High of 39°F, low of 33°F.
Basically, the "mild" January we've been having is officially over by next weekend. You’re going to want the heavy coat, the thermal socks, and probably some salt for your driveway if you're in one of the hillier parts of town.
Why the Forecast Changes So Fast
Gloucester weather is notoriously fickle. Because we're often caught between different pressure systems, a forecast that looks "partly sunny" on Monday can easily turn into "wet snow" by Wednesday.
Experts like those at the Met Office or local meteorologists often point out that the Severn Estuary plays a huge role in local microclimates. Sometimes the city center stays just warm enough to avoid the snow that's dumping on the nearby Cotswolds, while other times, the moisture from the river turns a simple cold snap into a thick, icy fog.
Actionable Next Steps for the Next 10 Days
Since the weather is turning, here’s what you actually need to do:
- Waterproof your gear now. Sunday and Monday are going to be wet. If your boots aren't treated, you're going to have a bad time.
- Check your heating. With temperatures dropping to 30°F by the 26th, make sure your pipes are protected and your thermostat is ready for the jump.
- Plan indoor activities for the 24th-25th. That rain-snow mix is the worst kind of weather for driving or walking. It’s slushy, slippery, and generally miserable.
- Watch the wind. Mid-week (the 21st especially) will be gusty. Secure any loose garden furniture or holiday decorations that might still be hanging on.
Stay warm out there. The end of January is clearly bringing the real winter bite we've been waiting for.
