Hi @KAKIFRY_DP Thanks for your question!
We’ve checked in with Glenda Cole to get an answer to your question, here is her response,
Like much of the world, temps have indeed increased in Portugal over the last few years. This kind of heat is unusual, but we had a similar heat wave across central Portugal and Spain two summers ago.
I live in the beautiful Algarve on the southern coast, where the sea breezes offset this heat.
