| 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. |
