What's the weather like in Suzhou by month?
Each month classified as peak (best balance of weather and value), shoulder (a step in either direction), or low season.
Why visit Suzhou during Apr–May, Oct–Nov?
The classical-garden season — wisteria blooms in March, peach and cherry blossoms in early April, peony in April-May, and the gardens are at their most photographic. April is ideal for weather and bloom; May begins to warm and the rainy season starts.
Shoulder season (Mar, Jun, Sep, Dec) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan–Feb, Jul–Aug) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
