Only six days the entire month were within one standard deviation of normal. On to the highlights:
In the Weather Bureau/NWS era (starting 1930)
- 10th coldest May
- Latest date (May 18th) of record with a daily high temperature below 40ºF and daily mean below freezing
- Three daily record low temperatures and two record low max temperatures
- Winter snowpack melt-out of May 11 is the second latest of record
- 18 days with daily low temperatures of ≤32ºF is most in May since 1964
- Green-up of West Chena Ridge as seen from UAF on May 26th is latest since observations began in 1974 and probably latest since 1964
- The 47 consecutive days with daily mean temperature below normal appears to be a record for such a streak, though it is not a record for consecutive days with departure of the same sign (53 days in a row in autumn 2002 above normal)
- Lowest April-May of record (mean temperature 31.3ºF)
- Fourth lowest March-April-May of record (mean temperature 23.2ºF)
- Daily record high of 84ºF tied on the 30th
- Five days with highs in the 80s ties for second greatest such days in May (record is seven days in 2011)
- First time ever in May with five straight days of highs 82ºF or higher (thanks to reader Brian for this one)
