Weather in June
Temperature
The arrival of June coincides with an average high-temperature of a fiery hot 95.5°F (35.3°C), indicating a minimal shift from May's 91.8°F (33.2°C). In the month of June, San Juan witnesses a consistent average low-temperature of 76.6°F (24.8°C).Heat index
For June, the heat index is calculated to be a blazing hot 122°F (50°C). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.Know that the heat index computations account for shaded terrains and slight winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
