Conditions at Horseshoe in May

May: Small but Clean

May is where the surf drops into small-wave territory. Average height sits around 2-3ft (0.8m), the period eases to 9.1s, and the swell is overwhelmingly from the ENE - 66.7% - with a secondary E component of 14.4% and NE of 13.6%. In terms of size, the 2-3ft (0.5-1m) class accounts for the vast majority of the month, meaning Horseshoe becomes a groveling, high-tide-friendly wave. Longboarders and fish riders are in their element, but there is little to get excited about for someone looking for a proper thumper.

Wind conditions offer more chances for clean surf. The wind rose starts showing a broader spread, with ESE 20.3%, SE 18.1%, E 16.1%, and SSE 11.2%, but also an increase in W/WNW/WSW flow - enough to nudge the ideal-wind score up to 12%. These westerly flows are offshore at Horseshoe, making the small NE/ENE swell clean and glassy. With water temp climbing to 29.4°C, air 28.3°C, and rainfall down to 4.9mm/day, May is a pleasant small-wave month for logging plenty of fun, shuffling sessions.
