Temperature Trends Through May
As spring formally yields to early summer, the city’s thermometer climbs steadily, reshaping wardrobe choices and activity planning for residents and visitors alike.
Average highs rise from the mid 60s at the start of the month to the low 70s by Memorial Day weekend, while overnight lows retreat from chilly 40s and 50s into a more comfortable upper 50s range across most neighborhoods.
This gradual warming invites lighter fabrics, open-air dining, and increased sidewalk activity, yet the occasional cool breeze off the Atlantic keeps a light layer advisable well into the month.
Rain And Humidity Expectations
May is notably wetter than the heart of summer, delivering roughly four inches of precipitation spread over nearly ten days on average.
Showers tend to be brief but intense, often arriving in the afternoon or early evening as unstable spring air collides with encroaching summer patterns, so keeping rain gear accessible remains wise.
Humidity stays moderate, rarely oppressive, making downpours feel fresher than the heavy, lingering dampness common later in summer.
