Weather in January
Temperature
In January, the average high-temperature registers at a still warm 28.9°C (84°F), nearly identical to December's 29.2°C (84.6°F). Acornhoek's temperature drops to an average low of 19.4°C (66.9°F) during the nights of January.Heat index
January's mean heat index is computed to be a tropical 33°C (91.4°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are highly critical for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
