February weather forecast
Rosario, Argentina

As the atmosphere settles following the heat wave of January, February offers slightly cooler weather conditions in Rosario. Compared to its predecessor, February exhibits a slight dip in temperatures and comes in a bit windy with wind speeds maxing out at 11km/h (6.8mph). In terms of sunshine duration, the city sees a minor decrease but nonetheless, the sun shines brightly for most part of the day. Cloud cover tends to increase, though not enough to significantly affect the pleasant weather. Soon, the weather turns the corner into March, revealing another facet of Rosario’s climate.

Temperature

Heat index

February's heat index is computed to be a very hot 35°C (95°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Heat index evaluations are typically in the context of light winds and shaded environments. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove 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. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Take precautions against overexposure. Protection against sun damage is needed. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
