Finally a reliable London weather forecast for your visit to London

Doing a long term weather forecast for London is very difficult because the weather in England and especially in London is very changeable.

(Nearer the time if you want to know the exact weather for when you’re here click London Weather Forecast and bookmark that page.)

It’s only when I started searching around the various weather websites it became clear to me that most sites were not making it easy for you to get a breakdown of what the weather in London is like each month.

Many London weather sites are not reliable

What I’ve done is looked at the various weather sites and by taking the averages of their weather data I’ve come up with an average monthly weather forecast for London.

But just to prove how difficult it is to forecast the weather in London here’s an example. The average rainfall in July noted by one website was over 20mm more than the average noted by another site.

That’s a huge difference and that’s the reason why I took averages from various sites so you could get a more accurate picture.

You’ll be able to see the average monthly temperature highs, lows and the average rainfall in mm. You’ll also see that although the quantity of rain isn’t a lot, it does rain often in every month.
