Weather in January
Temperature
The transition into January shows a subtle variation to a still warm 29.3°C (84.7°F) from December's 28.4°C (83.1°F) in the average high-temperature. January brings Kahawatta a consistent average low-temperature of 18.8°C (65.8°F).Heat index
In January, the average heat index is computed to be a fiery hot 36°C (96.8°F). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical 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.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
