While thunderstorms are forecast for parts of England today, it’s likely most of those will form to the west of London and thankfully miss those watching or taking part in the London river marathon.
In fact, it should be a decent day to be on the river with sunny spells for much of the day. A gentle easterly wind up the river might help too.
Also pretty warm with maximum temperatures reaching around 24C (75.2F) this afternoon.
