1870 - An unofficial 152.4 mm of rain, according to the Open Data Rescue Project.
1910 - 4.8 cm snowfall on May 28 was erroneous and eliminated, resulting in only 1.0 cm for the month. Observer notes from St John's College revealed that the rain amounts were mistakenly entered in the snow column for the date. Further evidenced by the fact that the snow amounts were entered when temperatures were 14-15c, far too warm for snow to fall. The observer, in their notes, also reported that rain was falling, not snow. The monthly summary from the observer showed no snow, and instead rain (4.8 mm) on the date. In addition, newspapers (note that this paper's 2.2 inches of rain is an error for 0.22 inches) had no mention of snowfall. They instead talked about rains that fell.
1938 - St John's College had 18.1 cm of snow.
2004 - Rainfall is considered estimated due to mixed precipitation on the 11th and 12th. Accuracy is within a few mm.
2012 - Decided to eliminate a spurious 0.5 mm on the 17th.
