The arrival of July marks a slight shift to an average high-temperature of a still moderately hot 29°C (84.2°F) from June's 27.2°C (81°F). A modest dip in temperatures to an average of 28.1°C (82.6°F) is observed throughout Onaga's July nights.

Heat index

The heat index for July is evaluated at a sweltering 35°C (95°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.

Resist overexposure. Safeguarding from solar damage is indispensable. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
