May weather forecast
Galaha, Sri Lanka

May, the last month of the spring in Galaha, is another tropical month, with an average temperature fluctuating between 21.8°C (71.2°F) and 30.1°C (86.2°F).

Temperature

May's advent denotes a minor fluctuation in the average high-temperature to a still hot 30.1°C (86.2°F) from April's 31.2°C (88.2°F). Galaha observes an average nighttime temperature of 21.8°C (71.2°F) during May.

Heat index

May's heat index is appraised at a very hot 38°C (100.4°F). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.
Note that heat index values are valued for light wind and location in the shade. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Resist overexposure. Safeguarding from solar damage is indispensable. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days.
