Weather in September
Temperature
Boyle marks the start of September with an average high-temperature of a moderately hot 85.5°F (29.7°C), hinting at a slight fluctuation from August's 89.1°F (31.7°C). Throughout the month of September, Boyle observes an average nighttime temperature of 67.1°F (19.5°C).Heat index
The heat index value during September is calculated to be a sweltering 95°F (35°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

The average daily maximum UV index in September is 5. A UV Index reading of 3 to 5 represents a medium health hazard from exposure to the Sun's UV rays for average individuals.Note: The maximum daily UV index of 5 during September translates into the following directions:
Preventative actions are necessary - The mandate to avoid skin and eye damage is in place. The Sun's radiation is especially intense around midday; try to stay in shade during this period. Stay sun-safe with clothing that is both closely woven and worn loosely.
