Weather in June
Temperature
The arrival of June brings an average high-temperature of a still hot 90.7°F (32.6°C), closely following the temperature pattern of May. Nighttime temperature experiences an average drop to a pleasant 72.7°F (22.6°C) in June.Heat index
June's average heat index is appraised at a burning hot 113°F (45°C). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.When referencing the heat index, its values are suitable for shady environments and light breezes. 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 'real feel' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. 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 largely significant for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

However, keep in mind that shade structures may not provide full sun protection. Boost your sun resistance with garments that are densely woven yet spacious.
