January weather forecast
Ca Mau, Vietnam

January in Ca Mau, Vietnam marks the start of the year with a relatively cool and dry phase. It offers a pleasant respite from the year-end humidity while preparing to usher in warmer temperatures in the subsequent months. The coolest temperatures of the year recorded between 23.9°C (75°F) and 30.5°C (86.9°F) make it a favored period for outdoor activities. As dryness dominates the air, remaining indoors might necessitate the use of humidifiers to prevent skin dryness. Towards the end of the month, a gradual rise in average temperatures signals the transition into a warmer February.

Temperature

The transition from December to January sees average high-temperatures adjusting to a tropical 30.5°C (86.9°F), from a not significantly different 29.8°C (85.6°F). In the month of January, the average low-temperature usually rests at a moderately hot 23.9°C (75°F).

Heat index

The heat index value for January is computed to be a very hot 37°C (98.6°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

The average relative humidity in January is 72%.

Note: The UV index of 7 during January leads to these advisories:
Shield from overexposure. Defense against sun-related harm is required. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
