Auckland's run of summer weather continued yesterday, with the mercury closing on a record set only four days ago.
But it looks like being back to umbrellas today - rain and even thunderstorms are forecast.
MetService forecaster Philippa Murdoch said: "There could be heavy rain with that and some hail."
Auckland reached 26C yesterday, a shade below Saturday's 26.8C - the hottest November day since 1959.
For many, yesterday would have felt even hotter as the warmth was combined with high humidity.
