Weather in June
Temperature
The shift into June is accompanied by a temperature increase, with the average high-temperature rising from a moderately hot 77.5°F (25.3°C) in May to a hot 87.1°F (30.6°C). June witnesses an average low-temperature hovering around a pleasant 69.8°F (21°C).Heat index
During June, the heat index is appraised at a very hot 100.4°F (38°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle 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 'apparent temperature' or 'real feel', determines the feeling of heat when you account for the relative humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. 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 highly important for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
