Nanjing has big temperature changes in early March—it starts warm at around 27°C, then drops sharply to 0°C, and there's rain even snow. Dress in layers: put on thermal underwear or a thin sweater as your base, add a fleece or thick cardigan, and finish with a windproof, water-resistant jacket. For rainy or snowy days, waterproof shoes are a must. Take a foldable umbrella and a scarf—you'll need them when temperatures suddenly drop, and the umbrella works for both rain and fog.
In mid-March, temperatures stabilize a little, roughly between 2°C and 21°C, and there's some rain and fog. Keep dressing in layers—the "onion-style" way: wear a long-sleeve shirt or light sweater inside, and pair it with a thin, useful jacket or windbreaker you can easily take off at noon. Jeans or casual pants work for your lower body. Bring waterproof sneakers if you plan to walk. For occasional showers, don't forget a small umbrella; if you're sensitive to pollen from early flowers, take a mask too.
Late March has warmer days (up to 33°C) but cool nights, along with showers near the end of the month and mild pollution. For daytime, wear light layers: put a short-sleeve or thin long-sleeve shirt under a breathable jacket. At night, add a thicker sweater or change into a warmer coat. Waterproof shoes are still useful for sudden rain. Take a foldable umbrella, a reusable mask for air quality, and a tote to hold the layers you take off when afternoons get warm.
Nanjing blooms with early spring scenery in March. Willow shoots sprout along Xuanwu Lake's banks, early cherry blossoms open gradually at Mochou Lake, and a walk on the Ming City Wall offers a full view of the "mountains, rivers, city and forests" landscape. The month sees frequent "spring marathons"—the "Rose Bridge" of Pukou Marathon has become a popular check-in spot, allowing runners to stop and enjoy the scenery along the way. Don't miss spring's seasonal foods: soft and fragrant qingtuan (glutinous rice cakes with green filling), savory scrambled eggs with Chinese toon, and warm duck blood vermicelli soup—hearty and authentic.
