Xi'an in February

April, May, September, and October give you the sweet spot — mild temperatures and clear skies perfect for outdoor sights. Spring brings blooming trees around the Big Wild Goose Pagoda, while autumn paints the City Wall parks in gold. Summer hits 35°C with sticky humidity that makes walking the Terracotta Army site miserable. Winter drops to -5°C, but crowds disappear and hotel prices plummet. The Chinese New Year period (late January/early February) brings massive crowds and closed attractions. Look, if you're coming for the warriors, avoid weekends year-round. Tuesday mornings at 8am when they open? You'll have the pits practically to yourself.
