Weather in January
Temperature
The coldest period is January, when temperatures fluctuate between an average high of 85.6°F and a low of 75.7°F.Heat index
For most parts of January, the heat index is estimated at a fiery hot 98.6°F. Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are extremely vital to babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
