Temperature
Phrae's average high-temperature in January sits at a tropical 31.2°C (88.2°F), showing little difference from the previous month. January in Phrae presents a pronounced difference from daytime highs, with a consistent average low-temperature of 15.7°C (60.3°F).
Heat index
The heat index value during January is calculated to be a torrid 39°C (102.2°F). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
