A wet Friday for Poole — keep an umbrella to hand
21 August 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
After the drama of recent days, today brings a more persistently damp picture for Poole. The Met Office forecast puts the chance of rain at 75%, with heavy spells possible at points during the day. The high will reach around 20°C — not cold by any means, but the rain will make it feel considerably less summery than the temperatures suggest.
The UV index is forecast at 6, which is on the moderate-to-high side even through cloud cover, so sunscreen remains sensible if you're spending time outdoors between showers. The overnight low will drop to around 11°C, so if you're heading out this evening, a layer on top of a waterproof is a good idea.
For families still making the most of the summer holidays, it may be worth saving any beach plans for a day with a brighter forecast — the harbour front and town quay can become quite exposed in a steady downpour. Indoor attractions, from the Waterfront Museum to the Lighthouse arts centre, make for a natural alternative on a day like this.
