June weather forecast
L'Observatoire, French Guiana

June, the first month of the summer in L'Observatoire, is still a tropical month, with an average temperature fluctuating between 30.4°C (86.7°F) and 21.8°C (71.2°F).

Temperature

With the onset of June, a modest change to a still hot 30.4°C (86.7°F) from May's 30.1°C (86.2°F) is noted in high-temperature. Throughout June, an average low-temperature of 21.8°C (71.2°F) is expected in L'Observatoire, French Guiana.

Heat index

June's mean heat index is estimated at a scorching 42°C (107.6°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Records show heat index calculations are tailored for shaded regions and mild winds. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'feels like' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.

Humidity

The average relative humidity in June is 89%.

Rainfall

In June, the rain falls for 22.8 days. Throughout June, 95mm (3.74") of precipitation is accumulated. In L'Observatoire, during the entire year, the rain falls for 259.3 days and collects up to 898mm (35.35") of precipitation.

Sunshine

In June, the average sunshine is 7.1h.

UV index

The average daily maximum UV index in June in L'Observatoire is 6. A UV Index reading of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for average individuals.
Note: An average maximum UV index of 6 in June leads to these recommendations:
Persist in precautions and follow sun safety policies. Keeping sunburn at bay is imperative. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
