, like December
, is a hot summer month in Salto
, with temperature in the range of an average low of 18.7°C (65.7°F) and an average high of 31.5°C (88.7°F).
January is the warmest month, with an average high-temperature of 31.5°C (88.7°F) and an average low-temperature of 18.7°C (65.7°F).
In January, the average heat index is calculated to be a very hot 36.8°C (98.2°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Note that heat index values are valued for light wind and location in the shade. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.Note
: The heat index, also known as 'real feel', 'apparent temperature', 'feels like', or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. This effect is individual, with diverse people perceiving weather differently for numerous reasons (metabolic differences, clothing, wind), and activity. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it is vital to remain hydrated, particularly during prolonged physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. If the body can not disperse the excessive heat and body temperature reaches conditions of hyperthermia, above 37.5°C (99.5°F) to 38.3°C (100.9°F), thermal conditions are potentially life-threatening.
January is the least humid month, with an average relative humidity of 63%.
In Salto, it is raining for 5 days, with typically 116mm (4.57") of accumulated precipitation. In Salto, during the entire year, the rain falls for 60 days and collects up to 1324mm (52.13") of precipitation.

The average sunshine in January in Salto, Uruguay, is 8.9h.
and December, with an average maximum UV index of 12, are months with the highest UV index. A UV Index reading of 11, and higher, represents an ultimate health vulnerability from exposure to the Sun's UV radiation for the ordinary person.Note
: In January, the average maximum UV index of 12 translate into the following recommendations:
Practice all essential precautions. Protection against sun damage is crucial. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure. Tightly woven, loose-fitting clothes provide additional protection from the Sun. A broad-spectrum sunscreen of SPF 30+ should be liberally applied and re-applied every two hours, and immediately after an outdoor workout or a swim.
