Our hot (or warmer) season is December to March/April, depending upon when he rains start. Then it cools off gradually until July. Yesterday was the first day that I wore something additional to stay warm on the commute. I prefer that as I don't have to worry about sweat on the way to work. I sleep better also during this season. Has something to do with sleeping in the basement growing up, where it never got warm even during hot summers.
Today was early morning club ride and the talk before the ride is it is cold today. That means next week i start using arm warmers during the ride.
Keep em rolling.
