Why is Massachusetts hot? Causes and heat countermeasures

I will explain in detail the causes of heat in the U.S. state of Massachusetts, measures to cope with it, and cool spots to visit.

1. Causes of Heat in Massachusetts

Massachusetts is located in the northeastern United States and is generally known for its relatively cool climate, but summers can be surprisingly hot. The main reasons are as follows:

1. Humid Continental Climate
   In inland areas, the moderating influence of the ocean is weaker, and days exceeding 86°F (30°C) are not uncommon. Particularly in the western inland regions, daytime temperatures tend to rise significantly.
2. Moist Air from the Atlantic Ocean
   While coastal areas tend to have slightly lower temperatures, high humidity makes the heat feel more oppressive. On days without sea fog, strong sunlight can quickly raise the temperature.
3. Impact of Heatwaves
   In summer, warm air from the southwest occasionally flows into the region, causing heatwaves that can last several days to nearly a week. During these periods, daytime temperatures can approach 95°F (35°C).
4. Urban Heat Island Effect
   In cities like Boston and Springfield, asphalt and buildings store heat, making it harder for temperatures to drop at night.

2. Heat Countermeasures

Here are some ways to stay comfortable during Massachusetts’ summer:

• Use Air Conditioning and Dehumidifiers Together
  On humid days, even just using a dehumidifier can significantly improve comfort.
• Protect Yourself from the Sun
  Use sunglasses, hats, and sunscreen. Coastal areas like Boston tend to have stronger UV rays.
• Avoid Going Out During Peak Heat
  From 1 p.m. to 4 p.m., temperatures are usually at their highest, so schedule outdoor activities for mornings or evenings.
• Stay Hydrated and Maintain Electrolyte Balance
  High heat and humidity increase perspiration, so sports drinks and salt tablets are effective.
• Block Direct Sunlight Indoors
  Use curtains or blinds to keep indoor temperatures lower during the day.

3. Cool Spots

Massachusetts has many coastal and mountain resort areas that remain relatively comfortable even in summer:

• Cape Cod
  Cooled by the Atlantic Ocean’s sea breezes, it’s more comfortable than inland areas and popular as a beach resort.
• Martha’s Vineyard and Nantucket
  While humid in summer, ocean breezes help lower the perceived temperature.
• The Berkshires
  A mountainous area in the west with higher elevations and cool air flowing through its forests.
• Cape Ann and the North Shore
  Located north of Boston, these fishing towns and scenic coastal areas offer cooler temperatures alongside beautiful views.
