July weather forecast
Apatou, French Guiana

On entering July, Apatou experiences further reductions in rainfall, receiving only 107mm (4.21") during the month. The tropical monsoon climate stretches into its home stretch, still nurturing every flora and fauna with abundant water. Similarly, temperatures persist at a comfortable range, supporting the active movements of the city's diverse wildlife. Lessened wind activity, compared to the first half of the year, ensures a calmer atmosphere. July holds the weather in transition, preparing the city to slowly step out of the monsoon season.

Temperature

With the onset of July, a modest change to a tropical 30.6°C (87.1°F) from June's 29.5°C (85.1°F) is noted in high-temperature. During July, Apatou experiences a consistent low-temperature average of 22.2°C (72°F).

Heat index

For most parts of July, the heat index is evaluated at a blistering 42°C (107.6°F). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.
Records show heat index calculations are tailored for shaded regions and mild winds. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

UV index

The months with the highest UV index are July through November, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high threat to health from unsafe exposure to UV radiation for the average person.
Note: The average daily UV index of 7 in July transforms into the following instructions:
Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
