January is a tropical winter month in
Pattani,
Thailand, with an average temperature fluctuating between 30.7°C (87.3°F) and 22.3°C (72.1°F).
Temperature
January's beginning signals an average high-temperature of a hot 30.7°C (87.3°F), barely different from
December's 29.6°C (85.3°F). January's nights observe an average temperature of 22.3°C (72.1°F).
Heat index
For January, the heat index is computed to be a scorching 40°C (104°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
Humidity
In January, the average relative humidity is 81%.
Rainfall
In Pattani, in January, it is raining for 6 days, with typically 51mm (2.01") of accumulated precipitation. Throughout the year, there are 141 rainfall days, and 1865mm (73.43") of precipitation is accumulated.
Sea temperature
The month with the coldest seawater is January, with an average sea temperature of 27.7°C (81.9°F).
Note: Surface water temperatures between 25°C (77°F) and 29°C (84.2°F) offer outstanding conditions for any water activity, providing extreme pleasure for extended periods.
Daylight
The average length of the day in January is 11h and 47min.
On the first day of January, sunrise is at 06:25 and sunset at 18:10. On the last day of the month, sunrise is at 06:32 and sunset at 18:23 +07.
