July weather forecast
Ahuachapan, El Salvador

July carries forward June’s temperament, albeit with some minor shifts in Ahuachapan. There is a noticeable decline in rainfall, down to 87mm (3.43"), suggesting a decrease in monsoon’s vigor. However, the frequency of rainy days remains pretty high. The departure of the first half of the year signals the slow transition into months with lesser rainfall and a gradual drop in humidity levels.

Temperature

With the onset of July, a modest change to a still warm 29.8°C (85.6°F) from June's 29°C (84.2°F) is noted in high-temperature. In the month of July, Ahuachapan experiences an average low-temperature of 20.3°C (68.5°F).

Heat index

July's mean heat index is estimated at a very hot 37°C (98.6°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Take precautions and adopt sun safety practices. Protection against sunburn is obliged. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. To cut down UV radiation exposure by about half, sport a wide-brim hat.
