Conditions at Brandon Bay in May
May: Small Summer Swell Sets In
May marks the true shift to fair-season surf. Average swell is 3ft (1.0m) and period shortens to 9.9 seconds, so the bay runs smaller and softer than spring's early months. Despite that, the waverose is still generous: WNW (24.8%), W (22.0%), NW (18.0%) and WSW (13.1%) provide a near-constant northern Atlantic supply. The wind rose becomes more northerly - NNW is the leading direction at 13.2% - and ideal offshore flow remains high at 33 percent. This creates a lot of clean, small-wave days that are perfect for longboards, funboards and getting back into the rhythm after winter. Water temperature climbs to 12.9°C, air averages 11.4°C, and precipitation is 2.60 mm/day. Chasing the occasional bigger W or WSW pulse will reward you with playful 3-4ft (0.9-1.2m) peaks on the better sandbars.
