March 2014 was the 4th coldest on record in Portland, and the coldest March in 47 years. Only 1950, 1956 and 1967 had colder weather in March than this year. Contrast the first graph below with the second. March this year had only 2 days more than 5 degrees above normal and 16 days more than 5 degrees below normal. March of 2012 had 17 days more than 5 degrees above normal and only 3 days more than 5 degrees below normal. The third graph below shows monthly averages vs normal for the 39 months I've had a weather station. Those two Marches are the warmest and coldest months relative to normal during that period. Despite the cold winter we have been through, this March was only the 2nd month in the last 39 that was below the 1951-1980 normals. The final graph show daily temperatures for March.
