Rain is the defining variable for golf in Boston in May. The month logs 14 precipitation days — tied for third-wettest in the year — which means you can expect wet intervals roughly every other day, even as temperatures finally climb into comfortable territory. The average high reaches 67°F, squarely inside the 60–80°F ideal range, and peak winds ease to 12.8 mph, the sixth-calmest reading of the year. The numbers set up a genuinely playable month, but rain timing matters more here than in almost any other month on the calendar.
The practical result is a rhythm of good windows interrupted by showers. Morning tee times tend to catch the drier stretches before afternoon fronts move through. The 17°F daily swing — lows near 50°F at dawn, highs at 67°F by midday — also means layers are not optional. Pack accordingly and you'll find May far more rewarding than its precipitation count suggests.
Book morning slots — ideally before 9 AM — to maximize the drier, calmer conditions before afternoon precipitation rolls in; with 14 wet days spread across the month, early tee times convert a coin-flip afternoon into a reliable round. See how conditions rate hour by hour on our playability scale.
April and May are identically wet at 14 precipitation days each, but May's average high jumps 11°F to 67°F, making the rain far easier to tolerate when dry windows appear. Moving into June, the high climbs another 10°F to 77°F while precipitation days tick up by one to 15, so June is marginally wetter and noticeably warmer — better for comfort, worse for staying dry. May sits between two months that each carry their own tradeoff, making it the coolest genuinely comfortable option on either side.
Climate normals show the long-term picture, but day-to-day weather varies. Check today's live golf weather score for Boston, MA for the current playability rating, hourly wind, temperature, and the recommended tee time window.

May averages 14 precipitation days, which ties it for the third-wettest month of the year alongside April, August, and December. That works out to roughly one in every two days carrying some rain, though most events are passing showers rather than all-day washouts. Building flexibility into your schedule — a morning backup slot or a midweek alternate day — is the most effective hedge.
The average high of 67°F puts May inside the ideal 60–80°F range, but the low drops to 50°F, creating a 17°F daily swing that catches many visitors underprepared for early tee times. A light waterproof layer and an extra glove handle the cool mornings, and conditions become genuinely comfortable once temperatures peak in the early afternoon. Players who start at dawn should treat it like a cool early-spring round, not a summer one.
