Honestly, if you're looking at the 14 day weather forecast for london england and expecting a simple "sunny" or "rainy" verdict, you're doing it wrong. London in late January is a mood, not just a temperature. It’s that weird transition point where the Atlantic is trying to be mild and the East is trying to freeze your toes off.
Right now, as of January 17, 2026, we’re sitting in a damp, cloudy soup. It’s about 48°F tonight with a light 5 mph breeze coming from the east. It's not "cold-cold" yet, but the humidity is hanging at 85%, which basically means that dampness is going to seep right through your "water-resistant" jacket.
The Two-Week Breakdown: Why the Jet Stream is Messing with Your Plans
The next few days are basically a repeat of today but with slightly more drizzle. If you’ve got plans on Sunday, January 18, expect a high of 51°F and a low of 42°F. It’s going to be "light rain" territory. Monday and Tuesday keep that 51°F–52°F trend, but the precipitation chance starts creeping up from 25% to 35%.
The Mid-Week Shift
By Wednesday, January 21, things get a bit breezier. We’re looking at 12 mph winds from the southeast. The high drops slightly to 48°F. This is where the "battleground" happens that the Met Office experts are talking about. You’ve got mild Atlantic air fighting against a high-pressure block from the east.

Is Snow Actually Coming to London?
This is the question everyone asks. The 14 day weather forecast for london england usually teases snow but rarely delivers the postcard-perfect version. However, the data for Sunday, January 25, and Monday, January 26, is looking interesting. We’re seeing a forecast for "rain and snow" with lows hitting 34°F–35°F.
Professor Adam Scaife and the team at the Met Office have been tracking this transition to colder weather for the end of January. While the first half of the month was dominated by Storm Goretti’s aftermath and milder air, the end of the month is seeing that "wintry hazard" risk increase.
By Friday, January 30, the BBC is actually forecasting sleet and snow with a low of 0°C (32°F). If you’re traveling, this is the window where the Heathrow-induced anxiety usually kicks in.

What to Actually Pack (A Realistic Guide)
Don't bring a massive arctic parka unless you want to sweat on the Central Line. London is about layers.
- A truly waterproof shell. "Showerproof" won't cut it when it's 51°F and drizzling for six hours straight.
- Leather boots or waterproof sneakers. Wet socks are the fastest way to ruin a trip to the British Museum.
- A light scarf. The 10 mph winds on Friday the 23rd will feel much sharper than the number suggests.
The Reality of London Humidity
People forget that London is very humid in January—often averaging 95% relative humidity. This makes 45°F feel much colder than 45°F in a dry climate like New York or Denver. It’s a "biting" cold that gets into your bones.
The sunset is currently around 4:20 PM. You only get about 8 hours of daylight, and most of that is filtered through a thick layer of grey cloud. If you see a patch of blue sky on Sunday morning, take a photo immediately; it likely won't last until lunch.

Actionable Insights for Your Visit
If you are navigating the city during this two-week window, prioritize indoor activities from January 20 to January 23 when the rain probability is highest. Keep an eye on the "WX Charts" maps if you're worried about the snow on the 25th; they show a purple shading (snow) heading toward the capital, but London’s "urban heat island" effect often turns that snow into slush before it hits the pavement.
Check the TfL (Transport for London) status daily if the temperature hits that 34°F mark on the 26th, as the Overground and northern sections of the Tube can be sensitive to ice. Stick to the museums or the Southbank Centre during the wettest days, and save your walk through Hyde Park for the "bright intervals" predicted for the 18th.
