Based on data collected from miniature weather stations deployed in the experimental plots, the total rainfall during the apple growth period (March to October) was 540.8 mm in 2019 and 423.0 mm in 2020. This dataset contains rainfall information for the apple growth period in the experimental field of Qingshuigou Area, Zizhou, Northern Shaanxi during 2019–2020. In 2019, there were 78 rainfall events. Specifically, rainfall from early April to late June totaled 162.4 mm, accounting for 30.0% of the total rainfall across the entire growth period. Rainfall was concentrated between late June and late August, reaching 238.8 mm, which made up 44.2% of the total growth-period rainfall. From late August to late October, rainfall decreased to 139.6 mm, accounting for 25.8% of the total. In 2020, there were 55 rainfall events. Rainfall from early April to late June was relatively low, at 49.4 mm, representing 11.7% of the total growth-period rainfall. Rainfall was abundant between late June and late August, with both the total rainfall amount and its proportion of the annual growth-period rainfall higher than those in 2019, reaching 307.6 mm and 72.7% respectively. From late August to late October, rainfall continued to decline, totaling 66.0 mm and accounting for 15.6% of the total growth-period rainfall.
