It's finally a comfortable temperature for desk working in our dining room. I'm usually in the loft but my wife has commandeered that room for the moment!
Our house is south west facing at the back but is a narrow terraced house which means that we don't get a huge amount of direct sunlight downstairs, except for the kitchen. Upstairs gets a lot more and so there is a big temperature range in the summer - along with the inevitable heat rising from bottom to top.
Today, the outside temperature has been high enough to open doors and windows which has pushed downstairs up to 20.5C . These days I find anything below about 19C feels cold after a few hours. Totally different of course at weekends when we tend to be much more active.
Heating is still on in the evening but only set to 20C so hopefully won't kick in tonight and I expect we'll switch it off soon.
