Weather in June
Temperature
June's onset records an average high-temperature of a warm 29.2°C (84.6°F), a near match to May's 30.2°C (86.4°F). June records a small disparity from daytime temperatures, marking an average low-temperature of 26.1°C (79°F).Heat index
The average heat index in June is appraised at a torrid 36°C (96.8°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
