July continues the trend set by
June, with heavy rainfall, high humidity, and high temperatures being the defining characteristics.
Tainan's weather during this period clearly embodies the traits of a tropical rainforest climate. A high rainfall is an integral part of July's weather profile, with the city receiving on average 358mm (14.09") of rain. Days are long, allowing for considerable exposure to sunlight despite the frequent showers. Therefore, July represents the heart of the wet season in Tainan.
Temperature
In Tainan, July is identified by the highest average temperatures, reaching a peak of 32.9°C (91.2°F) and a low of 26.4°C (79.5°F).
Heat index
Throughout July, the heat index is computed to be a burning hot 47°C (116.6°F).
Observe: Heat exhaustion and heat cramps are probable. Heatstroke is on the horizon with prolonged exertion.
Note that heat index values are valued for light wind and location in the shade. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. 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 particularly meaningful for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Note: The UV index of 12 during July translates into the following guidance:
Adopt all important safety measures, unprotected skin may burn rapidly. Remember that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. Make an effort to avoid direct sun exposure during these hours. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly. Sunscreen with an SPF of 30 or higher should be applied generously and frequently reapplied even on cloudy days, especially after each swim or outdoor workout. Be cautious! Sand and water surfaces make the Sun's UV rays more potent.
