Weather in January
Temperature
January, with its high-temperature average of 28.2°C (82.8°F) and a low-temperature average of 24.8°C (76.6°F), is the coldest month.Heat index
During January, the heat index is appraised at a hot 32°C (89.6°F). Continued exposure and engagement in activity might trigger tiredness and subsequently heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
