The shift into June reveals an average high-temperature of a still warm 85.1°F (29.5°C), closely mirroring May's climate. The June average low temperature, marginally lower than the daytime high, records at a still warm 80.1°F (26.7°C).

Heat index

During June, the heat index is estimated at a very hot 95°F (35°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. 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', is the outcome of merging air's temperature and its humidity metrics. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
