May weather forecast
Taiwan

May in Taiwan marks the commencement of the summer monsoon season, leading to significant changes in weather conditions. Northern Taiwan, including Taipei, sees temperatures ranging from 22°C (71.6°F) to 30°C (86°F). Rainfall increases substantially due to the onset of the monsoon, with an average monthly precipitation of about 235mm (9.25"). The weather during May is a mix of intermittent sunshine and heavy showers.

In central and southern parts of the island, temperatures typically fluctuate between 25°C (77°F) and 33°C (91.4°F). Cities such as Kaohsiung and Tainan may experience temperatures exceeding 33°C (91.4°F) on particularly hot days. The commencement of the monsoon season leads to an increase in rainfall in these regions as well, although it is still less than that experienced in the north.

Comparatively, May experiences higher temperatures and significantly more rainfall than the preceding month, April. Transitioning to the following month, June, May serves as a precursor to the height of the summer monsoon season. June is typically hotter and sees a further increase in rainfall, especially in the southern regions of Taiwan.
