The last month of the autumn, November
, is another hot month in Nan
, with temperature in the range of an average low of 18.5°C (65.3°F) and an average high of 31.2°C (88.2°F).
In Nan, Thailand, the average high-temperature in November is essentially the same as in October
- a still hot 31.2°C (88.2°F). In November, in Nan, the average low-temperature is 18.5°C (65.3°F).
In November, the average heat index is estimated at a blistering 41.6°C (106.9°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
Note that heat index values are valued for light wind and location in the shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.Note
: The heat index, also known as 'apparent temperature', 'feels like', 'felt air temperature', or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. This effect is individual, with diverse people perceiving weather differently for numerous reasons (metabolic differences, differences in body mass, height, and shape, clothing), and activity. 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 important for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it is vital to remain hydrated, particularly during prolonged physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. If the body can not disperse the excessive heat and body temperature reaches conditions of hyperthermia, above 37.5°C (99.5°F) to 38.3°C (100.9°F), thermal conditions are potentially life-threatening.
The average relative humidity in Nan is 80%.
In Nan, during 4 rainfall days, 18.1mm (0.71") of precipitation is typically accumulated. In Nan, during the entire year, the rain falls for 124 days and collects up to 1234.1mm (48.59") of precipitation.
The average length of the day in November is 11.3h.
The average sunshine in November is 8h.
In Nan, the average daily maximum UV index is 9. A UV Index reading of 8 to 10 represents a very high health risk from unsafe exposure to the UV radiation for the average person.Note
: The average daily UV index of 9 transform into the following instructions:
Take extra precautions. Fair-skinned individuals may get burned in less than 10 minutes. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. A wide-brim hat offers excellent sun protection for eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure. Tightly woven, loose-fitting clothes provide additional protection from the Sun. Even on cloudy days, a sunscreen with a minimum 30 sun protection factor should be generously applied and frequently re-applied, including after every swim or outdoor exercise.
