Notes
Times of extremes are computed using the midpoint of the longest continuous period at that extreme value.
Cumulative anomalies are reported according to the expected value for the month-to-date rather than month-end.
Sun hrs, Wet hrs, Cloud cover and Events are based on manual equipment/observations (entered with a delay of 1-10 days); their reliablity is questionable and they are provided for interest only.
