Weather in January
Temperature
Rorotan's coldest month, January, registers temperatures that range from a high of 29.6°C (85.3°F) to a low of 25.6°C (78.1°F).Heat index
The heat index value during January is computed to be a very hot 35°C (95°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.When assessing, remember that heat index measurements are for light winds and shaded spots. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. 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.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
