Early July in Nanjing is hot and humid—night temps usually hit 27°C (81°F), and day temps can reach 38°C (100°F). You need lightweight, breathable clothes: cotton T-shirts, shorts, summer dresses. The sun is strong, so bring a wide-brimmed hat, sunglasses and high-SPF sunscreen. It rains less early in the month, but sudden showers happen—carry a small umbrella or light rain jacket. For city exploring, wear comfy walking sandals or breathable sneakers. Humidity makes it feel hotter, so drink enough water and electrolyte drinks to stay hydrated.
Mid-July sees slightly cooler temperatures, with highs between 31°C and 36°C and lows around 25°C to 28°C, plus more cloudy days and occasional thunderstorms, with northeast or southwest winds. Wear light-colored, loose-fitting clothes such as skirts or short-sleeved tops to stay cool amid 81% humidity. Pack an umbrella for rain, and keep sunscreen handy as the sun can still be intense. Also, bring insect repellent to avoid mosquito bites, and a small first-aid kit with basic meds like pain relievers, just in case.
Nanjing cools down in late July: max temp drops to 26°C–34°C, and min temp stays between 23°C–27°C. More rainy days occur, sometimes with moderate rain or even heavy downpours, and winds are mostly from the northeast or east. Wear light layers—like a thin long-sleeve over a tank top—so you can adjust easily if it gets cooler after rain. You need a strong umbrella and rain boots for frequent rains, to avoid wading through water when going out. Take a small towel to wipe sweat and a reusable water bottle to add water in time; this helps you stay dry and keep hydrated.
In July, you can visit the Confucius Temple - Qinhuai Scenic Belt in Nanjing, watch the stage play Nanjing: Capital of Ten Dynasties, and enjoy the night tour to admire the reflections of lanterns. Don't miss the Huanhu "Super" Fragrant Carnival in Suojincun Village, where it's lively with crayfish, beer and live music. For food, salted duck and iced fermented glutinous rice wine are recommended to relieve summer heat; you can also try duck oil crisp sesame cakes and plum cakes to experience the traditional flavor of old Nanjing.
