August weather forecast
Tainan, Taiwan

The month of August represents the tail end of the wet season in Tainan. Although rainfall remains heavy and the city continues to experience high levels of relative humidity, subtle shifts can be observed in the weather parameters towards the end of the month. With a rainfall of 395mm (15.55"), August ranks the wettest month of the year.

Temperature

The initiation of August in Tainan, Taiwan, records an average high-temperature of a still hot 32.5°C (90.5°F), displaying a near consistency with the previous month. Throughout the nights in August, an average low-temperature of 26°C (78.8°F) is noted in Tainan.

Heat index

For most parts of August, the heat index is computed to be a burning hot 46°C (114.8°F). Take heed: Heat exhaustion and heat cramps are anticipated. Heatstroke is a potential outcome of continuous activity.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Note: The maximum UV index of 12 during August translates into these guidelines:
Carry out every crucial safety measure. People with fair skin may sustain burns in fewer than 5 minutes. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes. Despite the clouds, sunscreen with an SPF of at least 30 should be used liberally and reapplied frequently, especially after a swim or outdoor workout. Stay aware! UV radiation is magnified when reflecting off sand and water.
