Weather details in may
The climate throughout May in Sri Lanka corresponds to the first manifestation of the monsoon. Most Sri Lankan communities are disadvantaged by the abundance of rain and the resurgence of heat.
Colombo and the West Coast of the Island throughout April
The west coast is more exposed to the monsoon wind which favors the abundance of rain during the month of May. Even if heat is acceptable throughout the month, the weather in Sri Lanka throughout May on this part of the island is generally unfavorable.
Jaffna and the Extreme North of the Island throughout April
Unlike Colombo, which is experiencing heavy rain, Jaffna is much drier. However, the heat is unpleasant all day - the morning temperatures peak at around 30° C.
Trincomalee and the Northeast of the Island in April
The mornings and evenings are comfortable in the northeast of the island. The month of May remains favorable to discovering Trincomalee. The hours are decorated by a beautiful sunshine, from day to night.
Nuwara Eliya and the Central Plain throughout April
Despite the relative decline in precipitation, the uplands are still disadvantaged by the abundance of rainfall.

very badwarning in may the weather is different depending on the city and regions of the country.
Although it is not perfect the weather in Sri Lanka that month should be pretty good in Wilpattu National Park, Trincomalee, Dambulla and Anuradhapura. I allows to appreciate vacation in these areas. And even why not take a little time to take a nap at the pool under the sun!
If you do not go the sun and blue sky, but, for example to go sightseeing around, the cities of Kandy, Puttalam and Negombo have a just ok weather for this kind of activity in may. Eventually, it is not advisable to travel to Arugam Bay, Yala National Park, Hikkaduwa, Nuwara Eliya, Batticaloa, Udawalawe National Park, Neluwa, Galle, Bentota, Colombo, Ella, Kalutara and Jaffna in may because the climate is pretty bad.
