Weather in August

August begins in the city with the hustle and bustle of life carrying on, despite the persistence of the rainy season. August is a near twin of July weather-wise, with marginally lower temperatures and minimal changes in rainfall and humidity levels. While morning dew often veils the cityscape, the relatively cooler nights contrast the day time heat. And amidst all these subtle changes, the residents feel tuned to the rhythm of the rainy season. As the city waits for the dry season, August continues to infuse life into the terrain of Sunyani with its rain-caressed winds.

The advent of August in Sunyani, Ghana, observes an average high-temperature of a still warm 28.9°C (84°F), nearly identical to July's 28.8°C (83.8°F). Sunyani witnesses a consistent average low-temperature of 20.7°C (69.3°F) throughout August.

Heat index

In August, the heat index is estimated at a torrid 36°C (96.8°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. 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 especially vital to children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
