Weather in January
Temperature
With the advent of January, Summerdown experiences an average high-temperature of a still hot 30.7°C (87.3°F), mirroring a close resemblance to the previous month. During January, Summerdown's temperature averages to a pleasant 20.8°C (69.4°F) at night.Heat index
The heat index value for January is computed to be a tropical 31°C (87.8°F). With unrelenting exposure and activity, one might experience exhaustion, leading to potential heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. 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 highly important for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
