April is the month where changes in
Taichung's weather become more prominent. The city experiences its first major spike in rainfall, with a monthly rainfall increasing to 135mm (5.31") from 94mm (3.7") in
March. The city's temperature, too, follows this upward trend. The change in the city's weather suggests that Taichung is transitioning from its milder weather to the hotter, summer conditions.

Temperature
In Taichung, stepping into April brings a gentle temperature nudge, moving slightly up from March's warm 24.6°C (76.3°F) to a still moderately hot 27.6°C (81.7°F). An average low-temperature of 19.6°C (67.3°F) is observed during April nights.
Heat index
Throughout April, the heat index is calculated to be a hot 31°C (87.8°F). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
