Conditions at Gruissan in June
June: Summer Flat Begins
Gruissan enters the low season in June. Average swell height is a marginal 2ft (0.6m), average periods bottom out near 4.2s, and ideal wind drops to 12%. The swell rose still shows a healthy share of SSE and SE windswell, around 28% combined, but in practical terms this is short-period chop, not organised swell. WNW and NW directions account for over 38% of the wave rose and correspond to offshore tramontane flows, but they only groom an otherwise tiny, groveling surf. Water temperature reaches 20.0°C, air temps average 20.8°C, and precipitation is low at 1.09 mm/day. Summer thermal breezes kick in by late morning, so surfable conditions are an early-morning, small-wave affair.
