When to go
The beach-day index peaks in May and September–October; May scores 9.0/10 with highs of 29 °C, sea at 24.3 °C and 76 mm of rain.
In May that is 4.3 points above the median of the 2,466 beaches in United States covered by this atlas.
At its warmest the water here is 6.8 °C warmer than the United States median for August (22.5 °C).
Across the year the sea averages 23.4 °C, warmer than 72% of the coastal beaches in the atlas.
August is the wettest month (175 mm) and May the driest (76 mm); the yearly total is about 1,450 mm.
Daylight runs from 10.2 hours in December to 14.1 hours in June; in mid-May the sun rises at 05:50 and sets at 19:30 local time.
Orientation, sun and shore
The shore faces south-south-west (200°). Open water fills about 42% of the horizon close by, which makes it an open stretch of shore.
The sun sets over the sea in September–March; in mid-December it goes down at 16:45 local time on a bearing of 243°.
Straight out to the south-south-west about 800 km of open sea lies before the next coast, enough for large swells to build.
About 1 km offshore the sea is roughly 13 m deep and 17 m at 3 km. Behind the beach the ground is about 9 m above sea level 500 m inland and 16 m at 1.5 km.
Within 1 km, the land is 57% tree cover, 21% built-up land and 17% bare ground, sand or rock (satellite land-cover map, 2021): a partly built-up setting. Water makes up 53% of that circle.
