Honestly, if you've ever spent a Saturday morning trying to grab a coffee on the Marlow High Street, you know the weather here isn't just a topic of conversation—it's a lifestyle. People look at the "Weather Marlow Bucks UK" forecast and think they’re just seeing standard British drizzle.
They’re wrong.

Marlow has this weird, specific microclimate because of how it sits in the Thames Valley. It’s a town where you can be standing in brilliant sunshine at Higginson Park while watching a literal wall of gray clouds dump rain over the bridge toward Bisham. Today, Saturday, January 17, 2026, is a perfect example of that January mood. It’s 44°F right now, but with that southeast wind hitting 6 mph, it feels more like 41°F. Basically, it's "keep your coat zipped up" weather.
The River Thames Factor: More Than Just a View
Most people think the river is just there for the rowing and the pretty photos. But the Thames is basically a giant temperature regulator. In the summer, the water helps keep things a tiny bit cooler, but in the winter, it holds onto the dampness like a sponge.
That 95% humidity we’re seeing today? That’s the river talking.
It’s the kind of damp that gets into your bones. It’s why Marlow feels "colder" at 44°F than a dry 35°F would in the Scottish Highlands. The moisture in the air conducts the heat away from your body faster. Science, right?
And we can't talk about Marlow weather without mentioning the 1947 floods. It’s the local benchmark for "bad weather." Back then, the river was literally running out of the front door of the Compleat Angler. Even today, whenever we see a forecast for "light rain" like today's 35% chance, locals keep one eye on the river levels at the lock. It’s just how we live.
Surviving a Marlow Winter (and Enjoying It)
Today's high is 48°F, and we’re expecting light rain to stick around for the daytime before it turns just plain cloudy tonight. If you're heading out, don't trust the "light" part of "light rain."

Marlow rain is sneaky.
It’s often that fine mist that doesn't look like much but will soak you to the skin in twenty minutes. Since the UV index is a flat zero today, you don't need the sunblock, but you definitely need the boots.
Why the Forecast Says One Thing and You Feel Another
The current southeast wind is only 6 mph, which sounds like nothing. But in the valley, that wind can funnel through the streets and feel much sharper. When the forecast says it "feels like" 41°F, believe it.
- The Humidity Trap: 95% humidity means the air is nearly saturated. Evaporation is slow. If you get sweaty on a walk up Winter Hill, you’ll stay damp and get chilled the moment you stop.
- The Sunset Shift: As the day ends, the temperature is dropping to a low of 41°F. Because of the cloud cover, we won't get a "hard" frost tonight, but it’ll stay "raw" and clammy.
The Seasonal Truth: When to Actually Visit
If you’re looking at the weather Marlow Bucks UK data to plan a trip, everyone will tell you to come in July. Sure, July is the clearest month, and it hits those lovely 70°F averages. But honestly? Late September is the secret winner. The river mist in the morning is stunning, and the "cool season" (which starts around mid-November) hasn't kicked in yet.
Right now, we are firmly in the "cool season" which lasts until mid-March. February is technically the coldest month statistically, often bottoming out at 35°F. So, compared to what’s coming next month, today’s 44°F is actually a bit of a reprieve.
Actionable Tips for Today’s Weather:
- Footwear Choice: The paths along the Thames Path toward Hurley are going to be pure sludge today. Stick to the pavement or wear proper lugs.
- Layering: Since it's 44°F with high humidity, skip the heavy down parka if you’re walking. You’ll overheat and get damp from the inside. Go for a breathable waterproof shell over a fleece.
- Parking: If the rain picks up, the central car parks fill up fast as everyone abandons their outdoor plans for the cafes. Get in early if you’re heading to the shops.
Whether you're a local or just passing through, the weather in Marlow is rarely "extreme," but it is persistent. Take the 35% chance of rain seriously—usually, that means it’s going to rain on you, specifically, for about ten minutes, then stop just long enough for you to put your umbrella away.
To stay ahead of the damp, check the live river levels if you're planning a low-ground walk, and always assume the "feels like" temperature is the one that actually matters for your choice of knitwear.
