Spring and autumn layers
March–May and September–November can bring large temperature differences between mornings and afternoons. Pack a light jacket, breathable layers and rain protection; northern evenings may cool much earlier than southern ones.
Summer heat and rain
June–August is often hot and humid in eastern and southern cities. Choose breathable clothing, a hat, sun protection and a compact rain layer. Carry a light layer for air-conditioned trains and buildings; storms may change outdoor plans.
Winter varies widely
Northern and northeastern winters can be very cold; insulated outerwear, gloves and grippy shoes matter. Southern winters may feel damp indoors as well as outdoors. Hainan is milder, but a beach itinerary does not remove the need to check wind and rain.
Mountains and active days
Conditions at a summit may differ greatly from the arrival city. Bring walking shoes, a waterproof layer, sun protection and a small daypack. Discuss altitude and physical demands before choosing a route; rental safety equipment should be confirmed with the operator.
Business and cultural visits
Pack one neat business outfit and comfortable closed shoes. Temple visits call for modest clothing; factory visits may require long trousers, closed shoes and site-provided protective equipment. Check the destination forecast shortly before departure.
