What June feels like
The light lasts remarkably late this far north and east, which makes a June evening on the Eastern Prom the best free thing in the city. Fog off the water is common early in the month, and the Peaks Island ferry moves to its full summer schedule.
Expect about 7 days with real rain — enough to notice, not enough to plan around. Humidity stays comfortable; the air never feels heavy.
Can you swim?
The ocean runs about 57° — frigid — locals in wetsuits only.
