June weather forecast
Tainan, Taiwan

June welcomes the peak of the wet season in Tainan, with heavy showers and overcast days being the norm. The weather parameters clearly communicate the onset of this season, which the city adapts to with remarkable resilience. Notably, June experiences an impressive increase in rainfall, reaching a high point of 372mm (14.65") for the year. This surge in precipitation, coupled with a rise in temperatures and humidity levels, signals an intensification of the monsoon conditions.

Temperature

June's onset sees an average high-temperature of a still tropical 32.1°C (89.8°F), exhibiting a slight fluctuation from the previous month. Tainan's nighttime temperature in June drops to an average of 25.7°C (78.3°F).

Heat index

The heat index for June is computed to be a blistering 44°C (111.2°F). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Implement every essential safety step. Individuals with fair skin might receive burns in less than 5 minutes. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage. Even on overcast days, ensure the application and frequent reapplication of sunscreen with at least an SPF 30, especially post swim or outdoor exercise. Be wary! Reflections from sand and water make UV radiation more intense.
