The transition from May to June brings an average high-temperature of a moderately hot 29.8°C (85.6°F), barely different from May's 31.6°C (88.9°F). During June, San Esteban's temperature averages to a comfortable 19.8°C (67.6°F) at night.

Heat index

The heat index value during June is calculated to be a fiery hot 37°C (98.6°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air 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. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Shield from overexposure. Defense against sun-related harm is required. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
