I’m in Portugal too. It was bearable yesterday for the most part at around 35 and then around 3.30 it was like someone switched the external oven on and it suddenly shot up to around 40 degrees. I’ve never felt heat like it, really intense.
It’s set to be slightly hotter today and we’re on a wild fire warning (slightly in land north of Lisbon).
That said, we have air con and a pool which was distinctly lacking when we were in the SE at 35 degrees last week!
