Seasonal Variation in Precipitation
Santa Cruz do Sul experiences distinct seasonal variations in precipitation, influenced by the city’s subtropical climate. During the austral summer (December to February), rainfall is abundant, with monthly averages exceeding 150mm. The heavy rains are associated with the South Atlantic Convergence Zone (SACZ), which brings moist air from the Amazon Basin. In contrast, the austral winter (June to August) is relatively dry, with monthly precipitation below 70mm. This dry season is influenced by the movement of the SACZ to the north, reducing the moisture available in the region.
Spatial Distribution of Precipitation
Within Santa Cruz do Sul, the distribution of precipitation varies due to local topographic features. The city is situated in a valley surrounded by hills, which act as barriers to air flow. As a result, the southern and eastern parts of the city receive slightly higher levels of rainfall than the northern and western areas. This variation is attributed to the orographic effect, where air forced to rise over the hills releases moisture as rain on the windward side. On an annual basis, the city receives an average of 1,600mm of precipitation, contributing to its humid subtropical environment.
