I don't mind the heat as long as there is a breeze and is not too humid. Definatly cool nights for sleeping though.
My ideal day would be hot and sunny (25-30c) with a moderate breeze so it is comfortable to sit out, until about 6/7pm when the storm clouds build and, then, about 10pm there would be a storm/storms until 3am with rain, clearing by 6am to start another of my ideal days.
