Weather in July
Temperature
The transition from June to July brings a subtle temperature rise, with average high-temperatures increasing from 24.8°C (76.6°F) to a still moderately hot 27.8°C (82°F). An average nighttime temperature of 21.8°C (71.2°F) is recorded during July.Heat index
July's heat index is evaluated at a tropical 30°C (86°F). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', determines the feeling of heat when you account for the relative humidity. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
