Are you kidding me? ;<)
Mornings are about 5 Celsius right now and there has been some night frost too, recently. It can get cold, in ( this part of ) Portugal ( I am about one hour by car away from the highest mountains (Torre, Serra da Estrela, 1993 meters)
22 Celsisu is, honestly, quite a bit warmer than average for this time of year ( we are visited by a weather front from the Sahara/ Northern Africa ). I won't complain.
