July's climate in Antiguo Cuscatlán shows a minor adjustment in average high-temperatures to a hot 31°C (87.8°F) from June's 29.9°C (85.8°F). An average nighttime temperature of 21.9°C (71.4°F) is recorded in Antiguo Cuscatlán during July.

Heat index

The heat index for July is computed to be a blisteringly hot 40°C (104°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. 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. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
