Thursday is shaping up to be another scorcher in Barnes. The Met Office is forecasting sunny skies throughout the day, a high of 29°C and a low of 17°C overnight — with just a 2% chance of rain. The UV index is forecast at 9, which is classed as very high: sun cream, a hat and shade during the middle of the day are genuinely worth the effort.
After a run of hot days this week, it is worth being mindful of the cumulative effect of the heat, particularly for anyone elderly, very young, or with underlying health conditions. Keeping hydrated, avoiding strenuous activity in the early afternoon, and checking in on neighbours who may be struggling in the heat are all sensible steps.
Barnes Common, the Wetlands and the riverbank will be pleasant spots in the morning and evening when temperatures are a little lower. The river itself will be busy — if you are on or near the water, take appropriate precautions.
