June weather forecast
Jamaica, Cuba

June, the first month of the summer in Jamaica, is a tropical month, with an average temperature varying between 30.8°C (87.4°F) and 23.5°C (74.3°F).

Temperature

The commencement of June introduces an average high-temperature of a tropical 30.8°C (87.4°F), closely mirroring the preceding month. Jamaica's temperature drops to an average low of 23.5°C (74.3°F) during the nights of June.

Heat index

In June, the average heat index is appraised at a sweltering 39°C (102.2°F). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

In Jamaica, Cuba, the average relative humidity in June is 77%.

Rainfall

In June, in Jamaica, the rain falls for 19.7 days. Throughout June, 60mm (2.36") of precipitation is accumulated. In Jamaica, during the entire year, the rain falls for 209 days and collects up to 646mm (25.43") of precipitation.

UV index

April through October, with an average maximum UV index of 7, are months with the highest UV index. A UV Index value of 6 to 7 symbolizes a high health hazard from unsafe exposure to UV radiation for average individuals.
Note: In June, the maximum UV index of 7 translates into these guidelines:
Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. 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. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
