September can be cheaper and calmer, especially later in the month, but weather flexibility is essential.
September is a value-and-space month with real weather risk. It is still hot, humid and exposed to typhoon-season disruption, but demand can be softer before autumn returns and the city becomes more comfortable later in the month. It works best for flexible travellers who want lower pressure, better hotel leverage and a trip shaped around food, shopping, museums and clear-weather harbour moments.
