The Weather Today
Good morning! Today in London, we are expecting some beautiful, clear skies to start with. As the morning progresses, you'll notice the sunshine becoming a bit hazier due to some light cloud cover moving in. Temperatures will be quite pleasant, reaching highs of around 18 degrees by the afternoon. Winds will be light and variable, so it should be a lovely day to be outdoors
However, do carry a light jacket just in case it gets a bit cooler towards the evening, when temperatures will drop to about 12 degrees.
. 3-Day Forecast
Looking ahead, tomorrow is likely to start off overcast with the possibility of some light showers during the early afternoon. Temperatures will range from 13 to 17 degrees. Moving into the next day, expect a mix of sun and clouds, with the mercury hovering around 16 degrees for most of the day. Finally, in three days' time, we should see a return to sunnier conditions, but with a slightly cooler edge, as temperatures peak at about 15 degrees
So, it looks like a bit of everything coming our way – be prepared for some variable weather!
