When planning a trip to Santa Cruz de la Sierra, opt for light and breathable clothing made from natural fabrics, such as cotton or linen, as warm weather reigns here year-round. Comfortable walking shoes will be your best companion for exploring the city and its surroundings. Do not forget to bring sunscreen with high SPF, headwear (a hat or a cap), and quality sunglasses, as the sun in this region of Bolivia can be very active even on cloudy days. The principle of layering in clothing will also be very handy, allowing you to easily adapt to temperature changes during the day and between different seasons.

Although the climate in Santa Cruz de la Sierra is generally consistently warm, there are some seasonal nuances worth considering when packing your suitcase. During the wet season, which usually lasts from November to March, the number of days with precipitation increases. Despite the fact that the total monthly rainfall in millimetres is small (usually 3-5 mm), rains can be frequent, so a light raincoat or a compact umbrella will be very useful. In the drier and relatively cooler months, especially from May to August, when nighttime and morning temperatures can drop to 17-18°C, it is worth taking a light jacket, a fleece jumper, or a cardigan. This will ensure comfort during evening walks or early morning excursions when the air can be fresher.
