Weather in June

June maintains the established rhythm of a wet season with high rainfall averaging 138mm (5.43") throughout the month. Despite a small increment in temperature, the combination of high humidity and continuing cloud coverage gives an impression of a climate remaining in good balance. With decreased sunshine hours, June days have limited periods of clear skies. The sea water averages 30.2°C (86.4°F), reaching its highest yearly temperature.

Temperature

June's onset sees an average high-temperature of a moderately hot 29.7°C (85.5°F), exhibiting a slight fluctuation from the previous month. Acajutla observes a consistent average low-temperature of 26°C (78.8°F) throughout June nights.

Heat index

In June, the average heat index is evaluated at a very hot 35°C (95°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
Heat index details are generally centered around shaded locations and a mild breeze. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are of high significance for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
