Weather in July
Temperature
Transitioning into July, San Isidro records an average high-temperature of a still very hot 99.3°F (37.4°C), almost identical to June's 97.7°F (36.5°C). San Isidro experiences an average low-temperature of 78.4°F (25.8°C) in the month of July.Heat index
The heat index value for July is evaluated at a life-threatening hot 123.8°F (51°C). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.For clarity, heat index numbers account for light winds and areas under shade. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Protection should always be a priority. Skin and eyes are vulnerable without it. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
