Weather in January
Temperature
The average high-temperature during January matches that of the preceding month. An average low-temperature of 23.2°C is recorded in the month of January.Heat index
The heat index in January is computed to be a sweltering 38°C. Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial 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.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. 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. A hat with a broad brim is indispensable, filtering out up to half of UV rays. Caution! The reflection of sand and water significantly increases the intensity of the Sun's UV radiation.
