So, you’re thinking about a trip to the Palace Pier or a stroll through The Lanes? Honestly, if you're looking at the weather forecast UK Brighton for today, Thursday, January 15, 2026, you might want to pack a dry robe and maybe some waterproof boots. Actually, just bring the whole survival kit.
The Met Office has issued a Yellow Weather Warning for rain that is basically sitting right on top of Brighton and Hove. We are talking about a deepening area of low pressure migrating across the South East. It’s not just a drizzle; it’s that heavy, relentless English rain that turns the pebble beach into a splash zone.
What is actually happening today?
Right now, the temperature is hanging around 9°C, but with the wind whipping off the English Channel at 28 mph, it feels a lot more like 5°C. If you’re standing on the seafront, that wind is coming straight from the south, bringing all that moisture with it.
Met Office Deputy Chief Meteorologist Dan Holley has been tracking this system. He noted that while the exact path of these low-pressure systems can be a bit of a nightmare to predict, the result for Brighton today is "persistent and heavy" rain. We are expecting between 20mm and 40mm of rain to fall today alone. In some spots across the South East, that could even hit 70mm.
- Current Condition: Heavy Rain.
- High Temperature: 10°C.
- Low Temperature: 6°C.
- Wind Speed: Gusts up to 30 mph.
- Humidity: A whopping 94%.
Basically, it's soggy.
The 14-day outlook: Is there any sun coming?
Looking further ahead into the weather forecast UK Brighton, things don’t stay this dramatic forever, but "dry" is a relative term in January.
Tomorrow, Friday, January 16, looks a bit better. We’ll see some sunny intervals, though the temperature will stay around 10°C. It’s a classic Brighton "mix-and-match" day where you’ll be taking your coat off for five minutes and then zip it back up when the clouds roll in.
Saturday continues that trend with more sunny spells and highs of 10°C. It’s probably your best bet for a walk if you’re trying to avoid a soaking. By Sunday, the clouds return, and the temperature creeps up slightly to 11°C.
Moving into next week, from Monday the 19th through Wednesday the 21st, expect a lot of "grey." It’s that standard overcast Brighton sky that makes the Royal Pavilion look particularly moody. Highs will hover between 9°C and 10°C.
Why the Brighton weather is so weird
Brighton has this microclimate thing going on. You’ve got the South Downs behind you and the sea in front. Usually, the sea keeps us a bit warmer than London in the winter. But when a storm like Storm Goretti (which we just dealt with last week) or this current low-pressure system hits, there is nowhere for the wind to hide.
Most people get Brighton weather wrong by assuming it’s just "London weather but with a beach." It’s not. The humidity here—currently at 94%—means the cold gets into your bones much faster. A 45°F (7°C) day in Brighton feels much colder than the same temperature in a dry, inland city.
Specific advice for the next few days
- Check the trains: Southern and Thameslink hate heavy rain as much as we do. Saturated ground—which we definitely have right now—leads to "surface water flooding" on the tracks.
- Avoid the West Pier ruins: When the wind hits 30+ mph, the seafront can be genuinely dangerous with flying shingle. Yes, the pebbles can fly.
- Layers, not just a big coat: You'll sweat in a heavy parka while walking up the hills of Hanover, then freeze the second you hit the sea breeze.
- Waterproof everything: If you're out today, an umbrella is a joke. The wind will just turn it into a modern art sculpture. Use a raincoat with a proper hood.
The "Beast from the East" rumors
You might have seen some headlines about a new "Beast from the East" bringing blizzard conditions. While the Met Office is monitoring colder air attempting to push in from the east later in January, for now, Brighton is firmly in the "wet and mild" camp.
We might see some "wintry hazards" toward the end of the month (around January 29th), but for the next 10 days, your main enemy is liquid water, not the frozen kind.
If you are planning to visit, keep an eye on the weather forecast UK Brighton specifically for "wind gusts." A 10°C day is lovely for a coffee in the North Laine, but if those gusts stay above 25 mph, you'll want to stay indoors.
Actionable Next Steps: If you are in Brighton today, check the local flood maps via the Environment Agency, as the ground is already saturated from last week's rain. For those traveling over the weekend, Saturday morning currently looks like the only "clear" window for outdoor activities before the overcast conditions return on Sunday.
