January is a tropical winter month in
Phrae,
Thailand, with an average temperature ranging between min 15.7°C (60.3°F) and max 31.2°C (88.2°F).
Temperature
January's beginning signals an average high-temperature of a tropical 31.2°C (88.2°F), barely different from
December's 29.9°C (85.8°F). Phrae documents a substantial deviation from daytime highs with a consistent low-temperature of 15.7°C (60.3°F) during January nights.
Heat index
For most parts of January, the heat index is estimated at a very hot 39°C (102.2°F). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
