Weather in January
Temperature
Dumanjug records the coldest temperatures in January, averaging a high of 27.8°C (82°F) and a low of 24.3°C (75.7°F).Heat index
January's heat index is estimated at a tropical 32°C (89.6°F). Unrelenting activity during exposure could cause fatigue and potentially lead to heat cramps.Data suggests that the heat index is set for environments in shade and with a light wind. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. 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 particularly meaningful for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
