Extra Comments
Issues 22nd - 31st: Rainfall data is approximate and 10-min totals & rain rates are unavailable due to 5-min logging, but monthly sum is correct.
Observer Absent? Yes - observations may be unreliable
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.
