January weather forecast
Irundu, Uganda

January in Irundu, Uganda, is a hot winter month, with an average temperature varying between 31.9°C (89.4°F) and 16.8°C (62.2°F).

Temperature

January's onset brings a subtle temperature rise, moving from a moderately hot 28.9°C (84°F) in December to a hot 31.9°C (89.4°F). In January, the nighttime temperature plummets remarkably from the daily apex to a steady average of 16.8°C (62.2°F).

Heat index

In January, the heat index is evaluated at a torrid 37°C (98.6°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Humidity

In January, the average relative humidity is 61%.

Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
