Weather in January
Temperature
With January's advent, Santa Isabel do Rio Negro sees an average high-temperature of a still tropical 31.5°C (88.7°F), subtly shifted from December's 31.9°C (89.4°F). Throughout January, an average nighttime temperature of 22.7°C (72.9°F) is experienced.Heat index
During January, the heat index is calculated to be a scorching 43°C (109.4°F). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', gives a temperature feeling by integrating air temperature and humidity. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
