The first month of the winter,
December, is still a warm month in
Phrae,
Thailand, with an average temperature ranging between min 15.9°C (60.6°F) and max 29.9°C (85.8°F).
Temperature
Phrae's coldest temperatures are experienced in December, with average high temperatures of 29.9°C (85.8°F) and lows of 15.9°C (60.6°F).
Heat index
Throughout December, the heat index is calculated to be a sweltering 36°C (96.8°F). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.
Records show heat index calculations are tailored for shaded regions and mild winds. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
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. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
Humidity
In Phrae, the average relative humidity in December is 76%.
