On paper room temp is only 22C (which I think is much hotter than last may but still). However the evenings feel way hotter, sleeping on top of quilt already, I dont usually have to do this in May.
Keeping window open overnight it is pleasant by morning at least. Drops down to 21C by 6am, but that on paper 1C difference has a much bigger "feels like".
Yeah, I feel a big difference just going from 21c to 22c or 23c.
