Weather in January
Temperature
Cát Lái notes an average high-temperature of a still hot 31.9°C (89.4°F) in January, displaying minor variation from December. January generally records an average low-temperature of 22.9°C (73.2°F).Heat index
For January, the heat index is computed to be a sweltering 39°C (102.2°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Consider that heat index readings are for situations in the shade and light wind. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'real feel' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
