July weather forecast
Itamarati, Brazil

July, the same as June, in Itamarati, Brazil, is another tropical winter month, with temperature in the range of an average high of 31.8°C (89.2°F) and an average low of 20.2°C (68.4°F).

Temperature

The arrival of July is marked by an average high-temperature of a still tropical 31.8°C (89.2°F), bearing a close resemblance to June. July nights cool down to an average low-temperature of 20.2°C (68.4°F).

Heat index

The heat index value during July is calculated to be a blistering 42°C (107.6°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
In the scope of the heat index, its values resonate with shade and light wind conditions. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Humidity

The average relative humidity in July is 75%.

Rainfall

In July, the rain falls for 14.8 days. Throughout July, 43mm (1.69") of precipitation is accumulated. In Itamarati, during the entire year, the rain falls for 281.1 days and collects up to 1504mm (59.21") of precipitation.

Sunshine

In Itamarati, the average sunshine in July is 8.5h.

UV index

The months with the highest UV index are July through October, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high health risk from exposure to the Sun's UV radiation for average individuals.
Note: A daily high UV index of 7 in July leads to these guidelines:
Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
