Weather in January
Temperature
At the start of January, Andalatanosy's average high-temperature reaches a still tropical 30.6°C (87.1°F), subtly different from the preceding month. Andalatanosy's average low-temperature for the month of January records at a warm 23.8°C (74.8°F).Heat index
The heat index for January is appraised at a sweltering 37°C (98.6°F). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. 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.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
