A typical day in Katima Mulilo in January will greet locals and tourists with warmth as temperatures rest between highs of 31.3°C (88.3°F) and lows of 19.1°C (66.4°F). Pairing with these toasty conditions is a downpour of rainfall, coincidentally the most significant amount seen throughout the year. The aftermath of these showers beautifies this Namibian city with a rich humidity that hangs in the air. Despite the frequent rain, sunshine is a regular guest, with an average Ultraviolet (UV) index of 12, signifying the need for sun protection while stepping out during the day. Moving into February, a similar weather trend is anticipated, with only a slight dip in rainfall.

Temperature

The initiation of January sees an average high-temperature of a hot 31.3°C (88.3°F), showing minor variations from the previous month. The nighttime temperature shows a significant divergence from the daytime highs, averaging at a comfortable 19.1°C (66.4°F) in January.

Heat index

January's heat index is evaluated at a fiery hot 38°C (100.4°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. 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.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Note: In January, the maximum UV index of 12 translates into these guidelines:
Practice every essential safety step. People with fair skin could receive burns in fewer than 5 minutes. The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation. Use liberally and reapply a broad-spectrum SPF 30+ sunscreen every two hours, or straight away after any outdoor workout or swim.
