Shanghai in March is a changeable spring month: mornings and evenings can feel cool, afternoons may be mild, and rain or wind can quickly change outdoor comfort. Use the forecast for your exact dates, pack flexible layers and keep an indoor backup for long walking days rather than planning around one fixed temperature.
March conditions can change during the day, so build a flexible clothing and sightseeing plan around the forecast for your actual dates instead of an old temperature table.
Look at the current temperature trend, rain, wind and air-quality notice before leaving. A Bund walk, old-street route or park visit may feel very different in wet or windy conditions.
A light base layer, a warm mid-layer and a rain shell are easier to adjust than one heavy coat. Comfortable shoes matter because metro exits and historic streets can add more walking than expected.
Schedule the most weather-sensitive walking or riverside views for the clearest window, then use museums, cafés or shopping areas as a practical backup. Conditions and attraction notices can change after you leave the hotel.
