Extreme rainfall events are occasional, and understanding their intensity frequency is important for long-term planning public safety. The current study aims to investigate the stability of extreme precipitation in different regions Pakistan, independence uniformity occurrence. A analysis (RFA) was conducted based on information from 8 weather stations namely, distribution moments L annual maximum Pakistan were investigated; Using goodness-of-fit criteria, determined possible precipitation. Relatively Absolute Error (RAE) results most appropriate GUM distribution, revealed that Sialkot, Multan, Faisalabad DI Khan produce very low errors (0.266, 0.847, 0.075, 0.856, 1.671, 2.522, 3.659, 4.524). It found suitable LN Peshawar, Sibbi Karachi Stations. GEV also performs well with small various return periods 4.524), corresponding 2, 5, 25, 50, 100, 200, 500 1000 years. In contrast, P3 has advantage a period 10 years all stations, as they similar this particular period. research provides valuable insights into estimating at where data available
