, the same as December
, in Yangon
, is another hot winter month, with an average temperature varying between 17.9°C (64.2°F) and 32.2°C (90°F).
In January, the average high-temperature is almost the same as in December - a still tropical 32.2°C (90°F). In January, the average low-temperature is 17.9°C (64.2°F).
In January, the average heat index is computed to be a sweltering 38°C (100.4°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.Note
: The heat index, also known as 'felt air temperature', 'real feel', 'feels like', or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. This effect is subjective, depending on the activity and individual's heat perception influenced by various reasons (differences in body mass, height, and shape, wind, metabolic differences). 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. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
The least humid month is January, with an average relative humidity of 62%.
In Yangon, during 0.2 rainfall days, 5mm (0.2") of precipitation is typically accumulated. Throughout the year, there are 129.3 rainfall days, and 2681mm (105.55") of precipitation is accumulated.
The average length of the day in January is 11h and 15min.
On the first day of the month, sunrise is at 06:34 and sunset at 17:42. On the last day of January, sunrise is at 06:36 and sunset at 18:00 +0630.
, with an average of 9.7h of sunshine, are months with the most sunshine.
The average daily maximum UV index in January is 9. A UV Index reading of 8 to 10 represents a very high threat to health from exposure to the Sun's UV rays for the average person.Note
: In January, the average maximum UV index of 9 translate into the following recommendations:
Take special precautions, as unprotected eyes and skin can be burned and damaged quickly. 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 the 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.
