July 2013 – Weather Statistics for Watford UK


What a difference a month makes!! Summer arrived in July bringing the first above average month of the year. It was the 5th warmest July since records began. The highest temperature for the month in the UK went to Heathrow & Northolt with 33.5c the warmest since 2006.


The month ended at over 2.5c above it has also been noteworthy for how dry it has been. Here in Watford we had 20 continuous days of no rainfall (see stats below). It hasn’t been extremely hot but the nighttime temperatures have been quite high. There have been numerous big thunderstorms across the country but we have missed them here in Watford hence our relatively low rainfall amount. Most of the rain fell in the last 2 days in the form of showers.

Looking onwards into the rest of August it isn’t looking great on the latest computer models. It will still be warm but the jet stream will slip lower down to below the UK. This will mean there is a big chance of cooler periods. The SE of the UK should fare best with summer hanging on.

The weather information below come from my weather station in Watford.
