Notes
Times of extremes are computed using the midpoint time of the extremum (if the value persisted for >1 minute).
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; their reliablity is questionable and they are provided for interest only.
