Up where I live this is the sweet spot of the year for riding to work--cool mornings, warmer afternoons, early sunrise, late sunset for late commuter, no issues related to winter like cold, snow, and ice. It is the best time of the year, from about mid-April to mid-May, which is now. But there is some really hot and humid stuff in the forecast this week that's going to make it possibly sweaty in the morning, definitely sweaty in the afternoon. Less enjoyable.
So, enjoy it while it lasts, folks.
