May weather forecast
Dunagaha, Sri Lanka

May, the last month of the spring in Dunagaha, is also a hot month, with an average temperature ranging between max 30.8°C (87.4°F) and min 26.4°C (79.5°F).

Temperature

Dunagaha observes an average high-temperature of a still hot 30.8°C (87.4°F) in May, barely different from 32°C (89.6°F) in April. May records a small disparity from daytime temperatures, marking an average low-temperature of 26.4°C (79.5°F).

Heat index

In May, the average heat index is calculated to be a blisteringly hot 40°C (104°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Note: A daily maximum UV index of 6 in May translates into the following instructions:
Persist in precautions and follow sun safety policies. Keeping sunburn at bay is imperative. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Stay sun-safe with clothing that is both closely woven and worn loosely.
