What July feels like
July is Portland at capacity — the Old Port cobblestones are shoulder to shoulder and every lobster roll line runs out the door. Air conditioning isn't a given in older buildings, and a humid stretch off the water can make a third-floor walkup memorable.
Expect about 7 days with real rain — enough to notice, not enough to plan around. There’s a little humidity in the air, but nothing that changes your plans.
Can you swim?
The ocean runs about 61° — cold — a quick dip takes resolve.
