Weather in August
Temperature
The advent of August sees the average high-temperature at a fiery hot 35.2°C (95.4°F), subtly shifted from July's 33.3°C (91.9°F). Compared to daytime temperatures, São Francisco do Maranhão's temperature drops significantly, averaging an agreeable 22°C (71.6°F) during the nights of August.Heat index
Throughout August, the heat index is computed to be a fiery hot 39°C (102.2°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
