Use this month to capitalize on off-peak fares and smaller crowds at attractions in Taipei and Honolulu.

September travel between Daniel K. Inouye International Airport (HNL) and Taipei Songshan Airport (TSA) requires both sun-ready clothing for Honolulu and rain-ready gear for Taipei. Expect warm temperatures in both locations; however, Taiwan's late-summer typhoon season may cause delays.

Purchase travel insurance that includes weather-related trip interruption and medical coverage, and monitor typhoon alerts issued by the Taiwan Central Weather Bureau during your stay.

Inouye International Airport (HNL) and Taipei Songshan Airport (TSA) are uncommon; most itineraries include a single connection through East Asian hubs such as Tokyo Haneda (HND), Tokyo Narita (NRT), or Taipei Taoyuan (TPE).
