Weather in January
Temperature
La Réunion's average high-temperature marks a still moderately hot 28°C (82.4°F) with the advent of January, closely mirroring that of the preceding month. La Réunion's January nights witness minimal differential from the daytime temperatures, with averages of 27°C (80.6°F).Heat index
The heat index in January is computed to be a hot 32°C (89.6°F). If one endures exposure and continues to be active, it might result in tiredness and heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.

A UV Index value of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV radiation for average individuals.Note: The daily high UV index of 7 in January translates into this advice:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear. Caution! Sand and water surfaces escalate the UV intensity from the Sun.
