Hangzhou shows a fairly mild monthly swing: sample heat runs higher around Oct–Dec, softer around Jul–Sep (monthly sample means about 1.1–1.2). Spring Festival, National Day and bridged breaks often matter more than a leisure “season.” Index ≈ each hotel’s off-peak baseline—not a live city-wide rate.
