May: Winter Rhythm Sets In

May sees winter establish a firm grip on the Mornington Peninsula. The average swell is 1.5m (4.9ft), but the period stretches to 12.6s, giving the waves extra depth and push. While SW remains the primary swell direction at 43.9%, WSW energy grows significantly to 17.9%, and SSW contributes 11.3%. This broadening of swell angles brings a stronger westerly component, which can wrap into the break with more consistency. Wave heights are split between fun-sized 3-5ft (1-1.5m) and more substantial 5-6.5ft (1.5-2m) peaks, particularly from SW and WSW. The game-changer is the wind: ideal offshore conditions blow 24% of the time, with NNW leading the way at 18.2%, followed by NNW, NW (7.9%), and WNW (8.3%). This is the first month where offshore winds are a regular occurrence rather than a rare morning gift. Water temp drops to 15.4°C, air temp averages 14.1°C, and precipitation rises to 2.13 mm/day. May delivers clean, powerful waves with a much higher chance of groomed conditions - a high-quality month for Point Leo.
