Santa Cruz de la Sierra's Climate
Santa Cruz de la Sierra spreads across the low eastern plains of Bolivia on the edge of the Amazon basin, sitting at only about 400 m, so it stays hot and humid year-round under a tropical savanna climate (Aw). The wet season from November to March is hot and sticky with heavy showers and thunderstorms and temperatures around 30–35°C, while the dry season from May to September is milder, clearer and pleasant with warm days and cooler nights. Its signature feature is the surazo, a cold southern air surge that sweeps in during winter and can drop temperatures to 10–15°C within hours.
