Temperature

The advent of January signifies a minor shift to an average high-temperature of a still moderately hot 29.8°C (85.6°F), aligning closely with December. In the month of January, the average temperature dips to a still moderately hot 23.2°C (73.8°F) during the night.

Heat index

January's heat index is computed to be a fiery hot 37°C (98.6°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in 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 'feels like' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

January through December, with an average maximum UV index of 7, are months with the lowest UV index. A UV Index reading of 6 to 7 represents a high threat to health from exposure to the Sun's UV radiation for ordinary individuals.
Note: In January, a regular UV index of 7 translates into these guidelines:
Resist extreme sun exposure. Guarding against solar damage is essential. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
