So, you're looking at the 10 day weather forecast brighton and wondering if it’s finally time to dig out the heavy-duty thermals or if we’re just in for another week of "standard" British damp. Honestly, Brighton’s weather is a bit of a law unto itself. Being tucked between the South Downs and the English Channel creates this weird little microclimate where it can be sideways raining at the Marina while people are having a perfectly dry coffee in the North Laine.
Right now, we are staring down a transition. If you’ve stepped outside today, Saturday, January 17, 2026, you already know the vibe: grey, heavy, and very humid. We’re sitting at a high of 50°F with a thick 98% humidity that makes the air feel much heavier than the actual temperature suggests.
But things are shifting. The calm, cloudy start to the week is basically a fake-out before a "battle of the systems" kicks off over the Sussex coast.
The Immediate Outlook: Damp and Grey
Don't expect the sun to make a guest appearance anytime soon. Tomorrow, Sunday, January 18, is looking like a carbon copy of today—cloudy with a high of 51°F. It’s the kind of weather that’s perfectly fine for a Sunday roast at the pub but pretty miserable for a long walk on the pebbles.

As we move into Monday and Tuesday, the wind starts to pick up. We’re looking at 15 mph gusts coming in from the south and southeast. Because that air is coming off the water, it’s bringing rain. Light rain is forecast consistently from Monday, January 19, straight through the middle of the week.
Mid-Week Moisture
- Wednesday, Jan 21: The rain chance jumps to 45%. It won't be a monsoon, but it'll be that annoying, fine misty rain that soaks you to the bone in ten minutes.
- Thursday, Jan 22: Temperatures stay steady around 48°F. Still rainy. Still grey.
- Friday, Jan 23: This is where it gets interesting. Wind speeds hit 20 mph, and the precipitation chance spikes to 65%.
The Surprise Twist: Is Snow Actually Coming to Brighton?
Most of us who live here know that snow in Brighton is a rare beast. Usually, the salt in the air and the warmth of the Channel turn potential blizzards into sad, slushy puddles. However, the models for late January 2026 are doing something unusual.
By Sunday, January 25, the wind shifts. Instead of that "warmer" southern air, we start getting an easterly flow. Temperatures start to drop, hitting a low of 40°F. The 10 day weather forecast brighton shows a 20% chance of snow starting Sunday daytime.

The real kicker comes on Monday, January 26. We’re looking at a daytime high of 46°F, but as night falls, the temperature is predicted to crater to 34°F. The forecast is currently calling for a "rain and snow" mix.
By Tuesday, January 27, we might actually see some white stuff sticking. The high will only be 42°F, and with a north wind blowing in, that "feels like" temperature is going to be brutal. Advanced maps from WXCharts and recent Met Office long-range discussions suggest a small but powerful snow front could hit southern England right around this time. It's a classic battle between the Atlantic moisture and the Arctic air trying to push in from the east.
Why Brighton Weather Is So Hard to Predict
You’ve probably noticed that the forecast changes every three hours. That’s because the South Downs act as a physical barrier. Often, heavy clouds get "stuck" against the hills, dumping rain on us while places just a few miles inland stay dry.

Then there’s the sea temperature. Even in January, the water stays around 49°F. This acts like a giant radiator, usually keeping the seafront a couple of degrees warmer than the rest of the UK. It’s why we often dodge the "Big Freeze" that hits London or the Midlands. But when an "Arctic Blast" is strong enough to overcome that maritime influence, the result is usually a chaotic mix of sleet and coastal gales.
How to Handle the Next 10 Days
Basically, forget the umbrella. With 20 mph winds forecast for the weekend, an umbrella is just a broken piece of plastic waiting to happen.
- Waterproof everything: From Monday onwards, the rain chance doesn't really drop below 20%. A good shell jacket is your best friend.
- Layer for the humidity: 90%+ humidity means you’ll sweat if you over-layer, but you’ll freeze the second you stop moving. Think breathable wool.
- Watch the Monday/Tuesday transition: The shift from Jan 26 to Jan 27 is the one to watch. If that north wind stays strong, Monday night could be the first real "snow event" of the year.
Stay updated on the wind direction. If it stays coming from the South, we stay wet and mild. If it locks into the North or East, get the salt out for your driveway.
Check your tire pressure now. Coastal air and sudden temperature drops from 50°F down to 34°F can mess with your sensors and traction. If you’re planning to commute toward London or across the Downs toward the end of next week, keep a de-icer and a warm blanket in the car—just in case those 2026 snow maps actually get it right this time.
