When to go to Zhangjiagang: a seasonal guide

Spring: April and May are the sweet spots

March is still cool, with highs of 16°C, but it's a good month for walking. By April the air is mild and the city's parks feel fresh. May is warmer, with highs of 27°C, and it's still comfortable before the heavy rain starts.

Zhangjiagang is a Yangtze River port city, so spring is a good time to walk along the riverfront and visit Changjiang Lake. Qingming (tomb-sweeping day) falls in early April. It's a Chinese public holiday, so trains from Shanghai and Suzhou can fill up. The May Day holiday at the start of May is busier still, with domestic tourists heading to nearby water towns.

Summer: hot, sticky and wet

June brings the plum rains, the long grey, drizzly spell that hits the lower Yangtze region. It's rated Poor here, with rain on 13 days. July is the wettest month, with 233 mm over 17 days, and it's also hot and muggy, with lows of 25°C. August shares those 25°C nights and stays wet, though it gets a bit more sun.

If you must come in summer, plan museum, teahouse and mall time for the afternoons. Expect sudden downpours. School holidays run through July and August, so local families fill the parks and water spots. Hotels are still easy to find, since this isn't a big international tourist stop.

Autumn: the best all-round season

September is still humid and showery, so it's only Fair. Things turn around in October. You get 23°C highs, cool nights, and the most sun of the year at about 5 hours a day. November is crisper, with highs of 18°C, and it's still rated Excellent.

This is the time for a slow trip. Try river views, local Jiangnan food (the cooking of the lower Yangtze, often a little sweet) and day trips to Suzhou. Watch for China's National Day holiday in the first week of October. Trains and attractions get crowded then, so aim for mid-October or November.

Winter: quiet and damp

December is the driest month, with 31 mm of rain, and it's rated Good. January and February are colder, with lows of -1°C and 0°C. Skies stay grey and the damp makes it feel colder than the numbers say. Indoor heating can be patchy in this part of China, so ask about it when you book.

It's the quietest time for visitors, apart from Chinese New Year in late January or February. Many people travel then, and some local shops close for a few days. If you like empty streets and hot noodle soup, winter can work well.
