Weather in January
Temperature
In Guaíba, January and February are characterised by the peak of temperatures, recording an average high of 30.1°C (86.2°F).Heat index
In January, the average heat index is evaluated at a fiery hot 37°C (98.6°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
