Local processes that modify surface water properties are described. Temperature and salinity data from Oregon coastal waters during 1961 and 1962 are examined to assess the effects of the various processes. The temperature‐salinity pairs are divided into sets; each set is considered as dominated by a single modifying process. The set is defined by a process sector on a T‐S field. The percentage of observations in each process sector is determined; these provide a basis for quantitative comparison of different samples of data. During winter, rainfall is the dominant process all along the Oregon coast. Rainfall effects were found in 72% of the winter observations. During summer, two other processes dominate: along the northern Oregon coast, mixing with Columbia River water occurred 23% of the time; near Cape Blanco, upwelling in conjunction with heating was found 42% of the time.
