When to go
The beach-day index peaks in February–April and June–July; March scores 8.9/10 with highs of 29 °C, sea at 28.8 °C and 67 mm of rain.
In March that is 0.3 points above the median of the 22 beaches in Sri Lanka covered by this atlas.
At its warmest the water here is 0.6 °C warmer than the Sri Lanka median for May (29.4 °C).
Across the year the sea averages 28.7 °C, warmer than 94% of the coastal beaches in the atlas.
November is the wettest month (336 mm) and June the driest (42 mm); the yearly total is about 1,620 mm.
Daylight runs from 11.6 hours in December to 12.6 hours in June; in mid-March the sun rises at 06:12 and sets at 18:16 local time.
Orientation, sun and shore
The shore faces north-east (42°). Open water fills about 36% of the horizon close by, which makes it an open stretch of shore.
At no time of year does the sun set over the sea here: sunset bearings run from 247° to 294°, behind the land.
Sunrise is over the sea in April–August.
Straight out to the north-east about 1,200 km of open sea lies before the next coast, enough for large swells to build. The beach is on an island of about 65,961 km².
About 1 km offshore the sea is roughly 7 m deep and 54 m at 3 km, a shallow, gently shelving sea floor. Behind the beach the ground is about 9 m above sea level 500 m inland and 0 m at 1.5 km, a flat coastal plain.
Within 1 km, the land is 71% built-up land, 13% tree cover and 13% grassland (satellite land-cover map, 2021): an urban beach. Water makes up 40% of that circle.
- Built 71%
- Tree 13%
- Grass 13%
- Bare 3%
