July weather forecast
Puerto Morelos, Mexico

Moving into July, there is a notable dip in rainfall from June's peak to 81mm (3.19"), but the temperatures continue to soar. The sun shines brightly, sustaining the lengthy days and resulting in increased UV levels. Sea temperatures reach their highest making Puerto Morelos ideal for water sports. Despite the slight decrease in rainfall, humidity levels remain high, reinforcing the tropical appeal of this coastal town. The gentle wind provides a subtle respite from the otherwise sweltering weather.

Temperature

Puerto Morelos registers an average high-temperature of a still hot 30.9°C (87.6°F) at the commencement of July, closely related to the preceding month. Puerto Morelos encounters an average temperature dip to a moderately hot 26.7°C (80.1°F) throughout July, subtly lower than its daytime maximum.

Heat index

The heat index in July is estimated at a scorching 40°C (104°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
In terms of the heat index, values are set with light wind and shade conditions in mind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Humidity

In July, the average relative humidity is 77%.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. Remember that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. Make an effort to avoid direct sun exposure during these hours. Tightly woven clothing, when worn loosely, shields effectively against the Sun. Attention! UV radiation is markedly stronger with water and sand reflections.
