Sunday 13 September brings unsettled weather to Chiswick, with light rain expected through much of the day and a 73 per cent chance of precipitation, according to the Met Office. The temperature will reach a high of 22°C and stay relatively warm overnight at 18°C, so it is mild even if it is damp. UV index is low at 3, meaning sun protection is not a priority today.

The forecast notes the possibility of heavier rain at points during the day, so anyone with outdoor plans — a walk along the Thames Path, a trip to Chiswick House grounds or an afternoon in one of the local parks — would be wise to carry a waterproof rather than rely on the mild temperature alone.
For those making the most of the day indoors, it is worth bearing in mind that rail and bus journeys may take longer than usual given the District and Mildmay line closures affecting the area today. Building in extra travel time alongside wet-weather gear is the sensible approach for a Sunday that is more about comfort than sunshine.
