You've probably seen the postcards. Shimmering blue water, a lone rowing boat, and maybe a gentle mist clinging to the fells like a soft blanket. It looks peaceful. It looks, honestly, like a place where the sun always hits at that perfect golden hour angle. But if you’ve actually spent any real time here, you know the weather in Windermere Cumbria is a completely different beast than the one sold in gift shops.
It’s moody. It’s dramatic. Sometimes, it’s just plain wet.
The biggest mistake people make is checking the forecast once, seeing a little rain icon, and cancelling their plans. If you did that, you'd never see the Lake District. In this part of the world, "rain" isn't a reason to stay inside; it’s basically just the local atmosphere. Understanding how the climate works here—and why it’s so wildly different from, say, London or even Manchester—is the secret to actually enjoying your trip instead of shivering in a damp car park.
Why it Rains So Much (And Why That’s Good)
Let’s get the elephant in the room out of the way. Windermere gets a lot of rain. We’re talking about an average of 1,800mm to 2,000mm a year in the surrounding areas. For context, London usually gets less than 600mm.
Why the massive gap? It’s all down to a thing called orographic rainfall.
Basically, the prevailing winds blow in from the Atlantic, carrying a ton of moisture. When that air hits the Cumbrian mountains (the fells), it has nowhere to go but up. As it rises, it cools, the moisture condenses, and—boom—it dumps all that water right on top of us.

But here’s the thing: without that rain, Windermere wouldn't be Windermere. It wouldn’t have that lush, neon-green grass that looks like it’s been photoshopped. The lake itself wouldn't be the deep, impressive body of water it is. Locals often say there’s no such thing as bad weather, just the wrong clothes. And they’re right. There is something incredibly atmospheric about watching a storm roll across the lake from the window of a pub with a roaring fire.
The Four Seasons: A Reality Check
Most travel guides give you these neat little summaries of spring, summer, autumn, and winter. In Windermere, those lines are blurred. You can easily experience all four in a single afternoon.
Spring (March to May)
This is arguably the most beautiful time. Daffodils—the ones Wordsworth famously obsessed over—pop up everywhere. The average highs hover around 10°C to 13°C. It’s cool, but the air feels fresh.
- The Catch: May is statistically one of the "drier" months, but "dry" is a relative term. You’ll still get showers.
- What to wear: A light fleece and a high-quality waterproof shell. Don’t bother with an umbrella; the wind will just turn it into a modern art sculpture.
Summer (June to August)
July is usually the warmest month, with averages around 18°C or 19°C. Occasionally, we get a "heatwave" where it hits 25°C, and everyone acts like they’re in the South of France.
- The Vibe: The lake is bustling. The water temperature reaches about 16°C to 18°C, which is just about bearable for a swim if you’re brave (or have a wetsuit).
- The Reality: This is also when the humidity kicks in. Rain in summer often comes as heavy, thundery bursts.
Autumn (September to November)
Honestly? My favorite. The larch and oak trees turn these incredible shades of copper and gold.

- The Temp: It drops quickly. By November, you're looking at highs of 8°C.
- The Mist: This is the season for that famous lake mist. If you get up early for a walk at Orrest Head, you might see the "cloud inversion" where the valley is filled with white fluff and the mountain tops poke through like islands.
Winter (December to February)
It’s cold. It’s damp. It’s dark by 4:00 PM. Average lows stay around 1°C or 2°C, but the wind chill off the water makes it feel much colder.
- Snow: It doesn’t actually snow as much down by the lake as people think. The water acts as a giant radiator, keeping the immediate area slightly warmer. However, the fells—the high ground—will be white.
- The Perk: The crowds are gone. You can have a whole trail to yourself.
Microclimates: The Windermere "Bubble"
You might be in Ambleside and it’s pouring, but three miles down the road in Bowness, the sun is out. This happens all the time. Because of the way the hills are shaped, Windermere sits in a bit of a topographical bowl.
The south end of the lake (near Newby Bridge) often feels a bit milder and less rugged than the north end (towards Waterhead). If you’re planning a hike, never trust the weather you see through your hotel window. Check the Lake District Weatherline or the Met Office Mountain Forecast. The temperature drops about 1°C for every 150 meters you climb. If it’s a pleasant 12°C at the lakeside, it might be a freezing, windy 6°C at the top of a fell.
Survival Tips: Packing Like a Local
If I see someone walking around Bowness in a heavy denim jacket and white sneakers when the clouds are grey, I feel for them. Denim is the enemy here. Once it gets wet, it stays wet and gets heavy.
- Synthetic or Wool over Cotton: Merino wool is king. It stays warm even if it gets a bit damp.
- The "Three Layer" System: * Base: Wicking t-shirt.
- Mid: A fleece or a "puffer" jacket.
- Outer: A Gore-Tex or similar waterproof layer.
- Footwear: Even if you aren't "hiking," the pavements can be slippery and the grass is always boggy. Waterproof boots are a lifestyle choice here, not just gear.
- Sunscreen: This sounds like a joke, but the UV can be surprisingly high even when it's cloudy, especially if you're out on a boat and the sun reflects off the water.
What to Do When the Weather Turns
Look, it is going to rain during your stay. Accept it now and you’ll have a much better time.

When the heavens open, head for the Windermere Jetty Museum. It’s architectural eye-candy and keeps you dry. Or, hop on a Windermere Lake Cruise. The bigger boats have heated indoor cabins where you can watch the rain lash the windows while sipping a coffee. It’s actually quite cozy.
Alternatively, do what the locals do: put on your waterproofs, go for a short walk to see a waterfall (which looks better in the rain anyway), and then spend three hours in a pub like The Hole in t' Wall.
Actionable Next Steps for Your Trip
To make the most of the weather in Windermere Cumbria, don't just hope for the best. Be proactive with these steps:
- Download the MWIS (Mountain Weather Information Service) App: Even if you aren't a serious climber, their "Lake District" PDF is the most accurate forecast you'll find for this specific topography.
- Book a "Rainy Day" Backup: Keep a list of indoor spots like the World of Beatrix Potter or the Lakes Cinema in Penrith for when the clouds really settle in.
- Invest in a "Dry Bag": If you're going out on the water or hiking, put your phone and car keys in a small dry bag inside your backpack. Normal backpacks are rarely 100% waterproof in a Cumbrian downpour.
- Check the Webcams: Use the "Windermere Lake Webcams" online before you leave your accommodation. It’ll tell you exactly what the visibility looks like at the water’s edge in real-time.
The weather here isn't something to be "beaten." It's part of the landscape's personality. If you wait for a perfectly blue sky, you’ll miss the raw, moody beauty that makes Cumbria world-famous. Wear the boots, bring the coat, and just get out there.
