COMMENT
Well above average month for wind related events, culminating with a record gust of
170 kph (92 knots) for May. The previous highest gust in the May was 165 kph, also 
recorded on the 31st, back in 1987.
18 days of Gales (winds 34 knots and greater) is also a record for May. Previous best was
16 days.
Sunshine was well below average for May. Other Wx parameters fairly average.
cheers, Tim James
