Weather in April
Temperature
In Mahadeniya, March and April are characterised by the peak of temperatures, recording an average high of 31.8°C (89.2°F).Heat index
The average heat index in April is estimated at a blisteringly hot 42°C (107.6°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.Note that heat index values are valued for light wind and location in the shade. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', offers an insight into how hot it feels when we factor in moisture content. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are especially crucial for babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
