June weather forecast
Cozumel, Mexico

June introduces the wet season in Cozumel. Despite a rise in rainfall, it doesn't thwart the steady rise in temperatures, hinting at the sweltering days ahead. A profound shift in sea temperature to 28°C (82.4°F) favors divers and water sports enthusiasts. The UV index remains at its peak, necessitating careful sun exposure. Moreover, June records the maximum rainfall of 192mm (7.56") for the year.

Temperature

Welcoming June, Cozumel notes an average high-temperature of a still hot 32.4°C (90.3°F), nearly consistent with May's 32.7°C (90.9°F). Cozumel's nighttime temperature during June is consistently averaged at a moderately hot 23.8°C (74.8°F).

Heat index

The heat index value during June is computed to be a burning hot 48°C (118.4°F). Stay on guard: Heat exhaustion and heat cramps are predicted. Ongoing effort can cause heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Humidity

In June, the average relative humidity is 84%.

Rainfall

In June, the rain falls for 12.6 days. Throughout June, 192mm (7.56") of precipitation is accumulated. Throughout the year, there are 119.9 rainfall days, and 1490mm (58.66") of precipitation is accumulated.

Sea temperature

UV index

April through August, with an average maximum UV index of 12, are months with the highest UV index. A UV Index estimate of 11, and higher, represents an ultimate health vulnerability from unprotected exposure to Sun's UV rays for the average person.
Note: An average maximum UV index of 12 in June leads to these recommendations:
Employ every precaution of importance, unprotected skin and eyes could burn within moments. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized. A broad-spectrum sunscreen of SPF 30+ should be liberally applied and re-applied every two hours, and immediately after an outdoor workout or a swim. Warning! Reflective surfaces like sand and water amplify the Sun's UV radiation.
