It is unknown how much rain the Portland area may have had, but since records of rainfall amounts have been kept, in October of 2014, 1.56 inches of rain fell, breaking the old record of 1.31 inches set in 1951. By the time the rain storm was done, 1.83 inches of rain had fallen on Portland, but that was for more than a day's time.
It would be better to ask when doesn't it rain in Oregon.
Oregon gets a lot of rain, but Florida gets a lot of Tropical storms. Oregon has average temperatures, Florida is warmer and more humid.
