Human-induced climate change led to a rise in the occurrence and severity of extreme events, including droughts, on a global scale. The assessment of drought conditions is important in understanding and mitigating drought risk in the future. This study used 26 General Circulation Models (GCMs) of high-resolution NASA Earth Exchange Global Daily Downscaled Projections (NEX-GDDP) Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets and the standardized precipitation index (SPI) to assess the future of droughts in Central Europe (Poland) under four Shared Socioeconomic Pathways (SSPs) scenarios (i.e., SSP1–2.6, SSP2–4.5, SSP3–7.0, and SSP5–8.5). For this purpose, precipitation in the near future (NF) (2031–2060) and far future (FF) (2071–2100) periods were projected, and then an assessment of droughts at time scales of SPI-01, SPI-06 and SPI-012 was carried out. The projection of spatial variability of precipitation in Poland revealed that it will increase slightly (10–30%) under SSP1–2.6 and SSP2–4.5 scenarios, while in the FF, it is projected to increase by 20–50% under SSP3–7.0 and SSP5–8.5 scenarios in the north/central and south of Poland, respectively. Assessment of the future of droughts demonstrated that in the NF, the frequency of droughts will decrease by approximately 20–60% in all SPI timescales (SPI-01, SPI-06, SPI-12) under all SSP scenarios. In the FF, drought frequency will increase significantly, particularly under SSP3–7.0 and SSP5–8.5 scenarios, with 50–100% increases for SPI-06 (agricultural drought) and SPI-12 (hydrological drought).
