PDX April precipitation total of 5.73" sets record for the wettest April all-time at PDX. Records at the location date back to 1941. The all-time April rainfall record at various Portland locations still stands at 7.88" back in 1883. Portland Weather Service records for precip date back to 1871.
You may recall that April 2021 holds the all time record for the driest April with .39" of total Precipitation. Last year's dry April was the driest at any Portland location dating back to the year of 1871.

Total snow for April of 1.9" sets the record for the most April snow all time at PDX. Also, the .3" of snow on April 12th sets the record for the latest measurable snowfall of the spring season. I believe (although not positive) that the 1.6" of snow on April 11th is the most on any date so late in the season at all Portland record locations dating back into the 1800s.
I was surprised that despite cooler then normal mean temperatures 22 of 30 days, the average high, low and mean temperatures for the month failed to make the top 5 list for coolest Aprils, in fact the numbers were not close. April 2022 at PDX saw an average high of 57.9 degrees, which is -4.1 degrees below normal.
