Weather in April
Temperature
Weeraketiya sees its peak of temperatures during March and April, with an average high-temperature of 31.1°C (88°F).Heat index
April's heat index is estimated at a blistering 41°C (105.8°F). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.Heat index details are generally centered around shaded locations and a mild breeze. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
