Conditions at Curl Curl in May
May: The Quality Window Opens
May is the first month of the true best Surf Season. Swell averages 5-6ft (1.7m) with a season-best 9.7s period, moving into the powerful end of the mid-period spectrum. Ideal wind frequency jumps to 41%, driven by a dramatic increase in W (8.7%), WSW (9.7%), WNW (7.6%), NW (7.7%) and NNW (8.9%). Swell direction shifts with the season too: SSE (20.9%) is clearly the lead, S (14.7%) and SE (14.3%) follow, and E/ESE are still present around 8-10%. Water temperature drops to 21.0C, air averages 17.1C, and rainfall is a moderate 2.04mm/day. The combination of longer period, solid size and regular offshore flow means more days of clean, hollow, rippable sandbar waves. This is the month when Curl Curl's reputation starts paying off.
