's 30°C. During the month of January, the temperature in Singapore falls to an average of 23.3°C.
The average heat index in January is computed to be a sweltering 39°C. Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
Given the heat index, its values are aligned with shaded sites and gentle winds. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.Note
: The heat index, also known as 'real feel' or 'feels like', marries air temperature and humidity to produce a value illustrating perceived warmth. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

: A maximum high UV index of 12 in January translates into the following recommendations:
Utilize all vital precautions. Guarding against sun harm is non-negotiable. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears. Despite the cloud cover, sunscreen with an SPF of at least 30 should be generously applied and reapplied, particularly after a swim or an outdoor workout. Attention! UV radiation is ramped up when reflecting off sand and water surfaces.
