June weather forecast
Couasse, French Guiana

The first month of the summer, June, is also a moderately hot month in Couasse, French Guiana, with an average temperature ranging between max 28.8°C (83.8°F) and min 24.5°C (76.1°F).

Temperature

The arrival of June marks a slight shift to an average high-temperature of a still moderately hot 28.8°C (83.8°F) from May's 28.5°C (83.3°F). A mean low-temperature of 24.5°C (76.1°F) is anticipated during the month of June, a slight step down from the daytime high.

Heat index

The heat index value during June is computed to be a sweltering 35°C (95°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
Observations indicate that the heat index values are for shady locations with light wind. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. 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 extremely significant for babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Resist extreme sun exposure. Guarding against solar damage is essential. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
