Memorial Day Weather Outlook for Massachusetts: Rainy Start, Sunny Ending

Mark your calendars, folks – Memorial Day is just around the corner, and the sky over Massachusetts is playing a little game of hide‑and‑seek. The morning will begin with a curtain of light to moderate rain, especially across the eastern half of the state. Think of it as a gentle mist that won’t ruin plans but will make you reach for an umbrella or a quick dash indoors.

As the sun climbs higher, the clouds start to thin out, and by mid‑afternoon you’ll see the first hints of blue peeking through. The rain will taper off, leaving behind a few lingering showers that are more of a drizzle than a downpour. In the western uplands and along the Berkshires, the skies clear a bit earlier, offering a brief window of partial sunshine that’s perfect for a quick walk or a coffee on the porch.

Temperatures will be comfortably mild. Expect highs in the low‑70s along the coast – think 71‑74°F – while inland areas, particularly the central and western parts, will linger a few degrees cooler, topping out around 68‑70°F. Overnight lows will dip into the mid‑50s, so a light jacket is still a good idea for those early‑morning jogs.

Wind will be gentle to moderate, generally from the southwest at 5‑12 mph, keeping the air fresh without feeling too breezy. The humidity will hover around 70 % in the morning, dropping to the 50s as the sun breaks through, which should make the later part of the day feel quite pleasant.

For anyone planning a picnic, a beach outing, or a late‑day hike, the best bet is to aim for after 2 p.m. when the clouds are most likely to part. Keep an eye on the radar just in case a stray shower sneaks in, but overall, the day should be mostly dry from the early afternoon onward.

In short, pack an umbrella for the morning, but feel free to leave it at home for the afternoon. The mixed conditions give a bit of everything – a touch of rain, a dash of sun, and comfortable temps – perfect for a classic Memorial Day that’s both relaxed and a little adventurous.
