June weather forecast
Guanajay, Cuba

The first month of the summer, June, is a tropical month in Guanajay, Cuba, with an average temperature varying between 25.2°C (77.4°F) and 30.5°C (86.9°F).

Temperature

June commences with an average high-temperature of a hot 30.5°C (86.9°F), showing little deviation from May's 29.9°C (85.8°F). Throughout the month of June, Guanajay observes an average nighttime temperature of 25.2°C (77.4°F).

Heat index

June's average heat index is computed to be a very hot 39°C (102.2°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Humidity

The average relative humidity in June is 78%.

UV index

Note: The UV index of 7 in June translates into these instructions:
Act on precautions and pay attention to sun safety recommendations. Avoidance of sunburn is obligatory. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses.
