Conditions at Uliss in May
May: Maximum Southern Swell Direction, Questionable Wind
May sees the most consistent favorable swell direction of the year - S 42.6%, SSW 22.2%, SSE 17.5% and SE 10.2%, adding up to more than 90% from the southern half of the compass. That sounds great, but it is largely a product of the onshore summer monsoon. The wind rose is now dominated by SSE 22.0%, S 16.2%, SE 12.1% and SSW 10.4%, leaving only about 17.6% of observations in the offshore N/NNW quadrant. The average wave height is around 2ft (0.6m) and the period stays at 5.6s, so even the right directions are producing small, short-period windswell. On a lucky early morning with a land breeze or weak front, the surf can be rideable, but most of the time it is small and lumpy. Water temp reaches 8.9°C, air temp averages 10.1°C, and rain increases to 2.68 mm/day. Ideal conditions drop back to 8%; the windows are there, but you have to be sharp.
