    Boston weather May

    What's the weather like in Boston in May?

    Boston is the biggest city in the state of Massachusetts and sits on the east coast of the United States. It has a climate that brings cooler weather all year round, although things can heat up in the city over summer. Temperatures are warming up in May and it can be pleasant if you visit at this time. There are similar amounts of rain each month of the year in Boston, so this shouldn’t affect your choice of when to go.


    In May, the average temperature in Boston is 15ºC, reaching highs of 19ºC in the peak of the afternoon. These temperatures are great for exploring the city during the day, but the average low dips to 10ºC after dark so you’ll need to take some warm layers with you if you’re planning to stay out into the evening too. The city expects around 80mm of rain in May, so it’s a good idea to take a waterproof jacket in case you get caught in a shower.
