Honestly, if you’re trying to plan a two-week trip to the Big Smoke right now, you’ve probably realized that "settled" isn't exactly in the vocabulary. It is January 18, 2026, and the uk london weather forecast 14 days outlook is currently a messy tug-of-war between mild Atlantic air and a looming "Beast from the East" narrative that refuses to die.
Right now, we are sitting at a damp $50^{\circ}\text{F}$ (roughly $10^{\circ}\text{C}$) with humidity levels hitting a sticky 88%. It feels like breathing through a wet sponge. The immediate week ahead is essentially a slow slide from "mild and murky" into "bitter and bright."
The Immediate Outlook: Grey Is the New Black
The next few days are basically a repeat of the same grey sweater. Sunday is staying cloudy with a high of $52^{\circ}\text{F}$, while Monday brings light rain and more of the same. By Tuesday and Wednesday, the rain chance jumps significantly—up to 65% on Tuesday night—as a southeast wind kicks in.

You’ll want a proper raincoat. Not a cute "maybe it'll sprinkle" jacket, but something that actually stops the sideways London drizzle.
Breaking Down the Temperature Dip
By the time we hit next weekend, the mercury starts to quit.

- Saturday, Jan 24: Highs of $46^{\circ}\text{F}$ ($7^{\circ}\text{C}$) and lows of $38^{\circ}\text{F}$ ($3^{\circ}\text{C}$).
- Sunday, Jan 25: Things get even crisper, dropping to a low of $36^{\circ}\text{F}$.
Is the "Beast from the East" Actually Happening?
The Met Office has been tracking a potential transition to colder, drier conditions toward the end of January. While the first half of our 14-day window is dominated by Atlantic systems, the maps for January 28 through January 30 are starting to show those tell-tale purple blobs of snow risk.
Some models are hinting at a countrywide "snow blast" by January 30. WXCharts and recent Met Office long-range updates suggest we might see "wintry hazards" as high pressure tries to muscle its way in from the northeast. In plain English? It’s gonna get freezing. We are looking at daytime highs potentially stuck at $42^{\circ}\text{F}$ ($5^{\circ}\text{C}$) with a real risk of sleet or snow by Tuesday, January 27.

Packing for the London Rollercoaster
Basically, you need layers. A heavy wool coat is great for the tail end of this forecast, but for the next 48 hours, it’ll just make you sweat on the Tube.
| Date | Forecast Summary | Rain/Snow Chance |
|---|---|---|
| Jan 19 | Light rain, mild ($52^{\circ}\text{F}$) | 20% |
| Jan 21 | Damp, southeast winds | 45% |
| Jan 24 | Turning colder | 25% |
| Jan 27 | Potential sleet/snow | 20% |
The most surprising detail? Despite the gloom, the UV index is effectively zero. Your skin won't burn, but the lack of vitamin D is real. Londoners call this "The Big Grey."
Actionable Next Steps
If you are traveling or commuting during this 14-day window, here is how to handle it:
- Download a Radar App: Don't trust the "daily" icon. Check the live rain radar 15 minutes before you leave the house.
- Waterproof Your Shoes: The puddles at the bottom of the Underground stairs are deceptive.
- Plan Indoor Backups: If you had outdoor walking tours planned for the end of January, keep a few museum names (like the V&A or the British Museum) in your back pocket for when that northeast wind starts biting.
- Watch the Jan 28 Pivot: This is the date when the forecast could swing from "annoyingly wet" to "disruptively snowy." Stay tuned to local alerts around that time.
The uk london weather forecast 14 days is currently a story of two halves: a wet start followed by a freezing finale. Plan for both, or you’ll end up buying an overpriced "I Heart London" hoodie just to stay warm.
