Weather in June
Temperature
June's onset records a minor alteration in the average high-temperature to a still warm 83.7°F (28.7°C) from May's 80.6°F (27°C). A steady low-temperature average of 81.1°F (27.3°C) is logged during June, reflecting a modest dip from daytime readings.Heat index
June's mean heat index is calculated to be a tropical 91.4°F (33°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.One should consider that heat index numbers are for shaded settings and light wind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. 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 particularly meaningful for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.

Prevent overexposure. Protection from the sun's harmful effects is needed. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes. Caution! Sand and water reflections can notably increase the UV radiation intensity.
