Abstract Phytoplankton, the main contributor to ocean carbon and nitrogen fixation, responds rapidly physicochemical changes caused by hydrodynamics. To understand response of phytoplankton community succession monsoon‐driven hydrographic changes, we analyzed environmental data four cruises in southern South China Sea (SSCS) during different monsoon periods. The results revealed that communities interval (MI) period significantly differed from those Specifically, exhibited highest diversity owing pronounced heterogeneity sampling time MI. However, total abundance (4.2 ± 4.0 × 10 3 cells/L) was northeast (NEM) due nutrient‐rich conditions strong vertical mixing possibly induced western boundary current. Notably, diazotrophic cyanobacteria Trichodesmium (0.9–21.3 high abundances at edge anticyclonic eddy southwest (SWM) period. Moreover, (0.6–18.0 remained abundant primarily nitrogen‐limited areas with sufficient phosphate periods pre‐NEM NEM. Our study provides new insights into importance supplying monsoon‐influenced seas role variability shaping succession.
