For 4 months we slept under just a sheet. We still can, now at the start of October. Although then our cold feet will wake us around 5.
So we have taken the duvet out of the closet and put it on our feet. I wonder when it will be cold enough at night to want it around us all night.
When I exercise in the mornings I wear my jogging pants and my long-sleeved t-shirt. (I exercise outside on the roof). But the temperatures during the day are still a lovely 26 to 29 degrees.
