Another scorcher in Barnes today: 32°C with barely a cloud

The heat rolls on. Barnes is forecast to reach a high of 32°C today, with a low of 21°C overnight and just a 4 per cent chance of rain — making it another fine, dry August day for the neighbourhood.
The UV index is rated 8, which is classed as very high. Residents spending time outside, particularly with children, are advised to apply sunscreen (factor 30 or above), seek shade during the middle of the day, and keep well hydrated. The NHS recommends drinking at least six to eight glasses of water on days like this, and more if you're active outdoors.
Barnes Common, the riverside path and the Wetland Centre are likely to be busy. If you're heading to the Thames towpath, bear in mind the Teddington Lock safety advice issued last week — the river remains deceptively fast in summer despite its calm appearance.
Those travelling by public transport may find carriages warm; South Western Railway services have been running to amended timetables, so it's worth checking before you set off.
The Met Office forecast for Barnes confirms the sunny outlook, with fine conditions continuing through the day.
