Weather in July
Temperature
The transition from June to July sees an average high-temperature of a still hot 30.7°C (87.3°F), indicating a minor variance from the prior month. Dematagahapelessa, in the month of July, anticipates a consistent average low-temperature of 22.5°C (72.5°F).Heat index
In July, the heat index is calculated to be a very hot 38°C (100.4°F). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Experience reduced UV exposure by about half when donning a wide-brim hat.
