July weather forecast
Metapan, El Salvador

July marks a significant shift in Metapan's weather pattern, as the rainfall continues to decrease. Temperatures start to gradually decline with the city witnessing cooler days. The humidity remains high due to the preceding rainfall patterns of previous months. The reduction in rainfall combined with cooler weather conditions makes this an opportune time for outdoor activities. Favorable winds and longer sunshine hours provide the backdrop for enjoyable walks and picnics.

Temperature

The start of July sees the average high-temperature at a still moderately hot 29.7°C (85.5°F), showing little difference from June's 29.2°C (84.6°F). In Metapan, an average low-temperature of 18.9°C (66°F) is recorded during July nights.

Heat index

The heat index in July is calculated to be a fiery hot 37°C (98.6°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Note: A daily high UV index of 6 in July leads to these guidelines:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
