This annual event, which has been held for over a century, sees runners traverse the iconic course from Hopkinton to Boylston Street, enduring a wide range of weather conditions throughout its history. The marathon’s weather patterns have been as unpredictable as the race itself, with participants facing everything from snowstorms to scorching heat. The average precipitation for April in Boston is 3.63 inches, while the average snowfall for the month is 1.6 inches. On the specific date of the marathon, April 20, the average high temperature in Boston is 58 degrees Fahrenheit, with a low of 43 degrees. These figures provide a baseline for the expected conditions, though weather forecasts for the week leading up to the event suggest potential variability. StormTeam 5, the local weather service, will provide detailed updates as the race approaches, offering insights into the atmospheric conditions that runners and spectators can expect. Historically, the Boston Marathon has been shaped by its weather. Over the past 129 years, athletes have braved extreme conditions, from wintry precipitation to midsummer heat. Snow has fallen on the course at least five times, in 1907, 1908, 1925, 1961, and 1967. Driving rain has also disrupted the race, with notable instances in 1970, 2007, 2015, and 2018. These events highlight the race’s resilience to adverse weather, as runners have continued to compete despite the challenges. Unseasonable warmth has also posed significant challenges. The most extreme examples of heat occurred in 1905, when temperatures reached 100 degrees Fahrenheit, and in 1976, when much of the course reached 96 degrees.#stormteam_5 #boston_marathon #patriots_day #hopkinton #boylston_street
