July weather forecast
San Salvador, El Salvador

July brings a marginal reprieve from the rainy conditions that dominated June in San Salvador. Daylight hours continue to reduce, but clear days are not unusual. The UV index holds at 7 units, maintaining a constant requirement for sun safeguards. In contrast to June, rainfall decreases to 117mm (4.61") spanning 23.8 days, reinforcing the mildly decreasing humidity. Wind gusts reach 8.4km/h (5.2mph), proving slightly more brisk than previous months.

Temperature

During July, San Salvador observes a subtle ascent to a tropical 31°C (87.8°F) from June's 29.9°C (85.8°F) in the average high-temperature. Throughout July nights, San Salvador experiences a consistent temperature average of 21.9°C (71.4°F).

Heat index

July's heat index is calculated to be a blistering 40°C (104°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
Consider that heat index readings are for situations in the shade and light wind. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. 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 quite important for babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Take precautions and utilize sun safety practices. Protection against skin and eye damage is required. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. Sun protection is enhanced with clothing that boasts a tight weave yet offers a loose fit.
