The city is located on the west coast of Sri Lanka, about 30 km (18 mi) north of Colombo.
We are in the rainiest part of the coast, the one that receives abundant rains even in the period that runs from April to June.

However, since the sea is warm all year round, in theory they can also form from January to March, perhaps in a light form (such as tropical storms).
The best time to visit Negombo is from January to late February or mid-March, since it is the dry season.
In the months of July and August, there is another quite good period, in which the rains are relatively rare, however, this depends on the years, moreover, the sun shines less frequently and the sea is often rough, since the wind carried by the monsoon blows from the southwest.
