The 130th Boston Marathon is set to take place on April 20, 2026, and early weather forecasts are predicting mild and manageable conditions for the thousands of runners. While the Boston Marathon has historically faced a range of challenging weather, from snowstorms to extreme heat, the current outlook calls for temperatures between 55-60 degrees Fahrenheit and a slight chance of precipitation.

Why it matters

The Boston Marathon is one of the world's most prestigious running events, attracting over 30,000 participants each year. Favorable weather conditions can make a significant difference in the runners' performances and overall experience, as past races have been impacted by factors like heavy rain, high winds, and scorching temperatures.

The details

According to the Farmer's Almanac and forecasters from WCVB 5 Boston, the current prediction for the 130th Boston Marathon is for pleasant and mild weather, with temperatures ranging between 55-60 degrees Fahrenheit and manageable winds. However, the New England region is known for its unpredictable weather, and past Boston Marathons have faced a variety of challenging conditions, including snowstorms, heavy rain, and extreme heat that has even melted the pavement.

  • The 130th Boston Marathon is scheduled for Monday, April 20, 2026.
  • In 1939, runners began the race in the darkness due to a storm and a partial solar eclipse.
  • In 2010, a volcanic eruption in Iceland disrupted travel and caused many runners to miss the marathon.
