Conditions at Gruissan in April
April: More Direction, Less Power
April is the shoulder season personified. The frequency of favourable swell directions rises to nearly 40%, with SSE and SE combined making up over 26% of the wave rose, but average swell height drops to 3ft (0.9m) and period falls to 5.0s. This is a tease: the Gulf of Lion throws plenty of ESE/SE/SSE windswell at Gruissan, but much of it arrives small, short-period and onshore. Ideal wind falls to 18%, and afternoon sea breezes from SE/SSE become more common as spring warms the land. Water temperature climbs to 14.1°C, air temp averages 13.0°C, and precipitation rises to 1.93 mm/day. Surfable days still happen, but expect groveling conditions more often than not.
