May weather forecast
Hat Yai, Thailand

May's commencement in Hat Yai is characterized by a slight tapering of the scalding streak from the previous months. A pronounced increase in humidity blankets the cityscape, giving rise to the shimmering mirage effect known to tropical climates. The combination of this humidity and persistent heat creates a unique eco-climate for the city's flora and fauna. Despite a slight reduction in daylight hours, outdoor activities continue, albeit with necessary weather adaptations. The peak rainfall this year is recorded in May, reaching a significant 148mm (5.83").

The average high-temperature during May is a still hot 33.8°C (92.8°F), almost matching the conditions of the preceding month. May nights in Hat Yai are marked by an average low-temperature of 24°C (75.2°F).

Heat index

May's mean heat index is evaluated at a life-threatening hot 52°C (125.6°F). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Employ all crucial safeguards, unprotected skin could burn rapidly. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes. A sunscreen with at least SPF 30 should be used liberally and reapplied frequently on cloudy days, especially after swimming or an outdoor workout.
