If you’ve ever stood on Worthing pier with a face full of salt spray and a wind so strong it threatens to relocate your eyebrows, you know the weather in Worthing West Sussex is more than just a bullet point on a tourism brochure.
People talk about the "Sunny South Coast" like it's a constant state of being. Honestly? It’s complicated. Worthing definitely grabs more than its fair share of Vitamin D—averaging around 1,800 to 1,900 hours of sunshine a year—but that doesn't mean you should leave your raincoat at home.
The town is tucked between the English Channel and the South Downs. This geography creates a weird, wonderful microclimate. Basically, while the rest of the UK is shivering under a gray blanket of cloud, Worthing often sits in a "sun hole." But when the Atlantic decides to throw a tantrum, this town is on the front lines.
The Sunshine Myth vs. Reality
Let's get the big stat out of the way. Worthing is consistently one of the sunniest spots in the UK.
During the height of summer, specifically June and July, you’re looking at about 8 hours of sunshine a day. That’s massive compared to the North of England or Scotland, where 1,200 hours a year is considered a "good" run. But here’s the thing most people get wrong: sunny doesn't always mean hot.
The sea is a giant heat sink. In May, you might see clear blue skies, but that breeze coming off the water? It’s biting. The water temperature in the Channel rarely climbs above 18°C (64°F) even in August.
Because of this, Worthing has a "thermal lag." It takes longer to warm up in the spring than inland spots like Crawley or London, but it stays milder for longer when autumn hits.

Why the Sea Breeze is Your Best Friend (and Enemy)
On a scorching July afternoon, when London is pushing 30°C and everyone is melting on the Tube, Worthing is usually a comfortable 21°C or 22°C.
This is thanks to the sea breeze. As the land heats up, the air rises, and the cooler air from the sea rushes in to fill the gap. It’s a natural air conditioner.
But visit in February? That same mechanism turns into a relentless, damp chill that gets right into your bones. The humidity in winter often hovers around 85% to 90%. When it's 5°C with that level of moisture and a 20mph wind, it feels significantly colder than the thermometer suggests.
Breaking Down the Seasons: What to Actually Pack
If you’re planning a trip or moving here, forget the "average" charts for a second. Here’s the boots-on-the-ground reality of the weather in Worthing West Sussex throughout the year.
Spring: The Great Deception
March and April are "lightweight puffer jacket" months. You’ll see the daffodils out in Denton Gardens and think, "Great, spring is here!" Then a North-Easterly wind kicks in.
- Stats: Rain is actually lower in spring than in winter. May is often one of the driest months, with only about 6 days of rain.
- Vibe: Bright, crisp, but deceptively chilly.
Summer: Peak Worthing
This is when the town shines. August is technically the warmest month, with average highs of 20°C (68°F), though heatwaves can push this into the high 20s.

- The Secret: June has the most daylight and often the clearest skies.
- Reality Check: Thunderstorms. When the heat builds up over the South Downs and meets the cooler coastal air, you get spectacular electrical storms that turn the sea purple.
Autumn: The Windy Season
September is often beautiful—a "Second Summer"—but October is when the Atlantic depressions start lining up. This is when the wind speeds really pick up, averaging 20-22 mph.
- Precipitation: October and November are the wettest months. We’re talking roughly 80mm to 90mm of rain a month.
Winter: Mild but Gray
Worthing rarely gets proper snow. Being at sea level with salty air means anything white usually turns to slush before it hits the pavement.
- Temperatures: It rarely drops below freezing for long. Average lows are around 3°C to 4°C.
- The Storm Risk: Historically, January is when things get hairy. In 1951 and again in 1985, January storms were so bad that the sea actually jumped the prom and flooded South Street.
The South Downs Shield
You can't talk about Worthing weather without mentioning the hills behind it. The South Downs act as a physical barrier.
Often, you’ll see heavy rain clouds trapped on the "Weald" side of the hills (towards Horsham). Because of a process called rain shadow, the clouds dumped their moisture on the hills before reaching the coast.
I’ve stood on the seafront in bright sunshine while watching a wall of gray rain lash the hills just three miles north. It feels like you're in a different country.
Real Records and Weird Events
Worthing isn't just "mild and sunny." It has teeth.

The Great Storm of 1987 is still the benchmark for weather drama here. While Shoreham recorded 115mph winds, Worthing saw massive damage to its seafront structures and lost hundreds of trees.
More recently, the summer of 2022 saw the UK smash temperature records. While inland parts of Sussex hit 38°C, Worthing stayed a (relatively) bearable 32°C. That’s the power of the English Channel for you.
Survival Tips for the Worthing Climate
If you’re heading down, here’s how to handle the weather in Worthing West Sussex like a local:
- The "Layers" Rule: Never trust a sunny morning. If you're walking from the town center to the beach, the temperature will drop by 2-3 degrees the moment you cross the road at the Lido.
- Check the Wind Direction: If the wind is coming from the South or South-West, it’s going to be wet and "blowy." If it’s from the North, it’ll be clear but freezing.
- The Umbrella Trap: Do not use a cheap umbrella on the seafront. The wind will turn it into a useless metal skeleton in roughly four seconds. Get a wind-vented one or just wear a hood.
- Sunscreen is Non-Negotiable: The breeze masks the heat. You won't feel like you're burning because of the cool air, but that coastal UV is intense.
Final Verdict
Is the weather in Worthing West Sussex the best in England?
If you like sunshine and hate the oppressive humidity of London or the constant drizzle of the West Country, then yes. It’s a town of high pressure and big skies. Just don't expect it to be the South of France. It’s a rugged, coastal kind of beautiful where the weather is a daily conversation starter.
Next Steps:
Before heading down, check the Met Office "Inshore Waters" forecast specifically for the area between Selsey Bill and Beachy Head. This gives you a much better idea of the wind and "real feel" temperature than a standard city forecast. If you're planning a beach day, aim for late June for the best balance of long daylight hours and lower rainfall.
