Weather in August

As the year progresses into August, the rainfall notches up from 93mm (3.66") in July to 146mm (5.75"), heightening the wet season. The temperatures maintain their steady trend, not fluctuating much from the previous months. Strong sunlight persists, balancing the increase in rainfall, ensuring that the city doesn't feel exceedingly gloomy. The wind speeds remain comparatively constant, preventing any dramatic weather changes. Despite the increase in rainfall, Cartagena's vibrant energy and scenic attractions continue to be alluring.

Temperature

The transition into August in Cartagena shows a subtle variation to a still tropical 30.8°C (87.4°F) from July's 31.1°C (88°F) in the average high-temperature. Nighttime temperatures record an average of 26.8°C (80.2°F) throughout August.

Heat index

Throughout August, the heat index is calculated to be an extremely hot 40°C (104°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. 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 are particularly meaningful for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
