May: Small Summer Swell and the Sea-Breeze Fight
May is when the Azores High starts flexing, and average swell at Bournemouth slips to 0.8m (2-3ft) with periods dropping to 6.5s. WSW (23.6%) and SW (21.0%) are still the dominant directions, but much of that arrives below 1m, leaving a whole lot of small, short-period mush. The direct SE/SSE/S/SSW quadrant drops to 12.3%, and the offshore wind percentage falls to 14%. SW winds dominate the wind rose at 12.3%, and warm afternoons kick up a cross/onshore sea breeze nearly every day. Air temp averages 11.9°C, water is 11.6°C, and rainfall is at its lowest of the year at 1.65 mm/day. If there is a wave, it is groveller-grade; a longboard is the call.
