Weather in January
Temperature
The onset of January manifests an average high-temperature of a still moderately hot 27.8°C (82°F), demonstrating a minor variation from the preceding month. Throughout January, a modest shift from daytime highs is anticipated, with an average low-temperature of 24.2°C (75.6°F).Heat index
The heat index value for January is computed to be a tropical 32°C (89.6°F). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Consider that heat index readings are for situations in the shade and light wind. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', comes about by integrating the temperature readings with the humidity levels. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
