July weather forecast
Lábrea, Brazil

July, like June, is a hot winter month in Lábrea, Brazil, with temperature in the range of an average low of 20.9°C (69.6°F) and an average high of 33.6°C (92.5°F).

Temperature

July's onset records a minor alteration in the average high-temperature to a still tropical 33.6°C (92.5°F) from June's 31.8°C (89.2°F). The anticipated average low-temperature for July, an agreeable 20.9°C (69.6°F), shows a substantial deviation from the daytime maximums.

Heat index

For July, the heat index is computed to be an extremely hot 44°C (111.2°F). Watchful: Heat cramps and heat exhaustion are predicted. Continued exertion could lead to heatstroke.
Consider that heat index readings are for situations in the shade and light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. 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 66%.

Rainfall

July is the month with the least rainfall. Rain falls for 6.3 days and accumulates 6mm (0.24") of precipitation.

UV index

June through November, with an average maximum UV index of 7, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high threat to health from exposure to the Sun's UV radiation for the ordinary person.
Note: A maximum daily UV index of 7 during July morphs into the following directions:
Take precautions against overexposure. Fair-skinned people may get burned 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. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
