Weather in August

August, the last month of the summer in Sussex, is another tropical month, with an average temperature varying between 86.9°F (30.5°C) and 68.4°F (20.2°C).

Temperature

The onset of August marks an average high-temperature of a still tropical 86.9°F (30.5°C), hardly differing from July's 89.4°F (31.9°C). An average low-temperature of 68.4°F (20.2°C) marks the nights in Sussex throughout August.

Heat index

For most parts of August, the heat index is estimated at a fiery hot 100.4°F (38°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.
Be aware that heat index ratings are designed for shaded locations and minor breezes. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature 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. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. As body temperatures escalate without effective heat release, one might face dehydration threats.

Note: In August, a daily maximum UV index of 6 leads to the following instructions:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
