The UK Met Office’s latest long-range forecast indicates it is unlikely there will be a September heatwave in London. The outlook points instead to a changeable pattern at the start of autumn.
The report describes conditions for the coming period as “rather unsettled,” with cloud, rain and more variability than prolonged settled warmth. This contrasts with expectations sometimes raised during late-summer when warmer spells can occur.
Both outlets focus on the same forecast shift, highlighting that the long-range guidance does not support a sustained hot spell for London in September. While long-range weather forecasts are inherently less precise than short-term forecasts, the message is consistent across sources: the updated outlook leans toward unsettled weather rather than an extended heatwave.
