On March 14, TSR published their extended range forecast for the 2005 season, in which the anticipated that they would see tropical activity slightly below the average. They predicted that there would be a total of 25-26 tropical storms and 16 typhoons. The TSR, however, forecast that their number of intense typhoons would go slightly above the average, bringing their prediction of 10 intense typhoons. Their main reasons behind this is due to weaker trade force winds occurring in many parts of the basin, and there would be an enhanced cyclonic vorticity over the northwestern part of the Pacific. On April 27, the GCACIC made their first forecast for the season, expecting about 24 tropical storms developing, in which 15 of them would strengthen into typhoons. By May 5, TSR published their first forecast, still predicting a near average typhoon season. Around this time, 27-28 tropical storms, 17-18 typhoons and 9 intense typhoons were predicted, with the slight increase of the number of tropical storms were due to a slight increase in temperatures within the Niño 3.75 region.
