Wednesday brings another warm day in Chiswick, with temperatures reaching a high of 27°C and a low of 17°C overnight. Cloud cover is the main feature, but the Met Office reports just a 7% chance of rain and a UV index of 7 — high enough to warrant sun cream on any exposed skin if the clouds part. Met Office forecast
The fine spell that has settled over west London is expected to hold well beyond today, lasting a week or more according to the forecast. After the extreme heat earlier in the week — when Chiswick reached 34°C — the mid-to-high twenties will feel noticeably more comfortable, particularly for those working outdoors or getting about on foot or by bicycle.
Gardens, parks and the riverfront at Strand-on-the-Green should all be pleasant in the afternoon. Chiswick House and Gardens and the towpath along the Thames are good options if you want to make the most of the warmth without the full glare of a cloudless summer day. Carry water regardless — 27°C in humid conditions can still be tiring, especially for children and older residents.
