Brits are obsessed with the weather because when they finally get a weeks holiday, they want it sunny every day and hot. That does happen but is not guaranteed in Blackpool so they all went to Spain instead.
If you are staying Somewhere Different for a month, let’s say in February, it shows on average 10 days of the 30 days you will be here it will rain. That means it will rain for at least maybe 10 mins a day, or an hour, not all day. So most of the days, two-thirds of them it will be dry. On the days it does rain, it’s not all day. So the majority of the time you are here it’s not raining.
If you stay in July, you get 20 days of sunbathing, and on the days it rains, will not rain all day. You can get a tan, bike ride everywhere and get loads of work done on the days it does rain. It’s really not as bad as you have been told by Brits that you know 🙂
The house has full central heating so you will be as warm as toast in the winter when working at your desk and cool in the summer as it does not go above 30 for months at a time. Whatever month you come and stay the weather will not affect your work environment.
