Conditions at Windang Island in April
April: Westerly Belts Arrive
April marks a clear step toward the winter season. The ideal wind percentage jumps to 33%, average wave period rises to 9.4s, and swell height remains at around 6ft (1.7m). Swell direction becomes more southerly: SSE carries 19%, SE 16%, ESE 13%, E 13%, and true S adds 12%. Most of the swell is concentrated in the 3-6.5ft (1-2m) bands, with a solid supply of 6.5-8ft (2-2.5m) groundswell from the S/SE direction. This means the island's east-southeast exposure is seeing plenty of S/SE band energy, and it is increasingly groomed by W, WNW, NW and NNW offshores, which together account for around 28% of the wind distribution. Cold fronts pushing across southern Australia create a repeating rhythm of fresh SW/W winds followed by clearing offshore flow. Water temperature eases to 22.0°C, air temperatures average 15.8°C (min 4.3°C, max 31.9°C), and rainfall is relatively low at 2.22 mm/day.
