What this forecast is built from

  • Source: MET Norway Locationforecast (backup source)
  • How far it goes: 48 hours (2.0 days), one value per 60 minutes
  • The primary forecast source was unavailable, so this location is running on the backup source, which publishes a shorter hourly horizon.
  • Columns are hidden when the source does not publish that measurement for this location, rather than showing an invented number.

Hourly timing is the least certain part of any forecast, and days six through eight are far less certain than tomorrow. Rain can arrive earlier or later than the hour shown. Official warnings always take precedence.

Common questions about Boston, Massachusetts weather

How accurate is the Boston, Massachusetts forecast?
The next 48 hours are usually reliable on temperature and sky cover, with timing that can shift by an hour or two. Days three and four are dependable for the overall pattern. Beyond that, treat the numbers as a planning direction rather than a promise — we label confidence on every day so you can judge for yourself.
When will it rain in Boston, Massachusetts?
No day in the current outlook has a rain chance above 40%, so conditions look favorable for outdoor plans across the week.
Where does this forecast come from?
Forecast values come from national weather model data, and official warnings come from the National Weather Service. We show the source and the last-updated time on every page, and we never invent a number the source did not publish — missing measurements are hidden, not guessed.
How often is this page updated?
The forecast refreshes whenever the source model publishes new data, typically several times a day. The freshness note near the top of the page shows exactly when the numbers you are looking at were issued.
