Boston Marathon · April 2027

Weather & climate

Major weekend operating notes

01 · Historical band

5–14°C, with a 30% historical rain signal

This is planning context, not a forecast. Use it to pack options rather than choose one fixed race kit.

02 · Start wait

Dress for standing still

The day begins at Start. Bring a removable layer that works before the gun without becoming dead weight on course.

03 · Decision point

Switch inside seven days

Once the live forecast is available, prioritize hourly temperature, wind, rain timing, and the feels-like value at your wave.

Typical race-week temperatures run 514°C with about a 30% chance of rain on any given day. Dress for the start-line wait, not the finish — you'll warm up fast once the gun goes.

Race-week forecast window

Opens April 9 · 226 days away

Today's New York weather is not race-week weather.

TripRace unlocks the live seven-day forecast only when it can cover race morning. Until then, use the historical range and pack-for-the-wait guidance on this page.

Forecast loads live; the climate normals above are baked in and don't change.
