Cloudy and warm for Poole today, but keep an eye on the sky
26 August 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
Wednesday brings a mostly cloudy day to Poole, with temperatures reaching a comfortable 23°C and not dropping below 18°C overnight — so it stays mild even after dark. The Met Office is flagging a 50 per cent chance of rain today, along with the possibility of a storm at some point during the day, so it is worth keeping an umbrella within reach if you are heading out. UV index is moderate at 5, meaning sun cream remains sensible on any brighter spells. Full forecast details are available on the Met Office website.
The storm risk is a particular one to watch for anyone planning time on or near the water — Poole Harbour and the bay can change quickly when conditions deteriorate, and the RNLI and harbour authority always advise checking the latest marine forecast before setting out. The harbour master's office publishes up-to-date conditions for those with boats.
For anyone with plans at Poole Quay or along the beach this afternoon, the advice is the same as any unsettled late-summer day: enjoy the warmth while it holds, and have a plan B ready. Temperatures remain very pleasant for August, and any heavy spells are likely to be short-lived rather than an all-day washout.
