Weather in July
Temperature
With the start of July, Valle de San Juan measures an average high-temperature of a still tropical 32.8°C (91°F), not significantly differing from June's 32.5°C (90.5°F). Despite considerable daily temperature swings, a steady low-temperature average of 20.6°C (69.1°F) is noted throughout July.Heat index
The heat index value for July is calculated to be a very hot 38°C (100.4°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', shows a temperature sensation when both heat and moisture conditions are combined. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

January through April, July through October, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for the average person.Note: A maximum high UV index of 7 in July translates into the following recommendations:
Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. To best shield against UV radiation, choose sun-safe garments and dependable sunglasses.
