May, the last month of the spring in
Phrae, is another very hot month, with an average temperature ranging between min 24.7°C (76.5°F) and max 35.3°C (95.5°F).
Temperature
The advent of May signifies a minor shift to an average high-temperature of a still sweltering 35.3°C (95.5°F), aligning closely with
April. Phrae experiences an average low-temperature of 24.7°C (76.5°F) in month of May.
Heat index
May's average heat index is calculated to be a burning hot 54°C (129.2°F).
Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
Humidity
In May, the average relative humidity is 74%.
