July weather forecast
Santa Ana, El Salvador

July is a near mirror-image of June's weather characteristics, with slight reductions in temperature and rainfall. The skies appear more overcast with the persisting high cloud cover. Despite the monsoons, outdoor activities can thrive due to the lingering daylight hours. The wind velocity tends to pick up slightly during this season. The average pressure is reported at 1012.8mb, the peak for the rainy season.

Temperature

The shift into July finds Santa Ana at an average high-temperature of a still warm 29.7°C (85.5°F), closely comparable to June's conditions. Throughout the month of July, Santa Ana observes an average nighttime temperature of 18.9°C (66°F).

Heat index

July's mean heat index is evaluated at a torrid 37°C (98.6°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.
Heat index evaluations are typically in the context of light winds and shaded environments. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
