What May feels like
The Esplanade fills with runners and the sailing dinghies come back to the Charles. Keep a jacket for the evening — the sea breeze makes the last few blocks toward the water noticeably cooler than the rest of town.
Expect about 7 days with real rain — enough to notice, not enough to plan around. The air runs dry — whatever the thermometer says, it wears easy.
