By Sri Lanka is currently experiencing extreme heat following a period of heavy rainfall. With temperatures soaring to dangerous levels in several regions, many are wondering: Why is it so hot, and when will the rain return?
Why Is It So Hot?
Reduced Rainfall & Clear Skies
With the recent drop in rainfall, cloud cover has significantly decreased. This allows more direct sunlight to reach the ground, increasing daytime temperatures.
Stronger Solar Radiation
Sri Lanka is nearing the time of year when the sun moves directly overhead (March-April), leading to intense solar radiation. This natural phenomenon drastically increases heat levels.
Weak Winds & Stagnant Air
Low wind speeds reduce natural cooling, trapping heat in the atmosphere and making it feel hotter than the actual recorded temperature.
High Humidity Levels
The combination of heat and humidity creates a suffocating environment, making temperatures feel even more extreme.
Heat Absorption & Retention
During the day, the earth absorbs solar radiation. At night, this stored heat is slowly released, preventing significant cooling.
Seasonal Changes & Delayed Monsoon
Sri Lanka is currently in its inter-monsoon period, causing fluctuating weather patterns. The southwest monsoon, which typically brings relief, is expected to arrive only by late May.
Rain
According to the Department of Meteorology, slight rainfall may be expected around February 24, offering temporary relief. However, heat levels are predicted to peak in late March and early April before gradually decreasing with the arrival of the southwest monsoon.
How to Stay Safe in the Heat
To cope with the ongoing extreme heat, health and weather experts recommend taking precautions. It is essential to stay hydrated by drinking plenty of water and avoiding direct sunlight during peak hours, especially between 11 a.m. and 3 p.m. Wearing light-colored, loose-fitting clothing can help minimize discomfort, while taking breaks in shaded or air-conditioned areas will reduce the risk of heat exhaustion. Parents are also advised never to leave children or pets in parked vehicles, as temperatures inside can rise dangerously fast.
As Sri Lanka braces for one of its hottest seasons, staying informed and taking necessary precautions is crucial. While temporary rainfall may bring short-lived relief, real change will only come with the arrival of monsoon rains in May. Until then, the country must prepare for an extended period of sweltering conditions.
