Jun 1878 - Missing data on the 23rd and 30th. St Andrews was used to fill the voids on these dates. It was chosen over Stony Mountain because it appeared to follow more closely to the obs at St John's College. This lowered the average high for the month from 26.2°C to 26.1°C.
Jun 1972 - For some reason, overnight temperatures were ignored in the ECCC Archives on the 19th. The 13.9°C high shown was actually in the afternoon, but higher temperatures occurred overnight. I have used the maximum hourly value of 16.1°C at midnight as an estimate for the daily high, given falling temperatures through the night. This raised the average high for the month from 25.2°C to 25.3°C.
Jun 1988 - Note that in the ECCC Archives, they show 22.0°C for mean temperature in the monthlies but 22.1°C in the dailies. The dailies value is the correct one.
Jun 1991 - Unsure where the original low of 11.7°C on the 6th came from in the ECCC Archives. The minimum hourly value was only 15.9°C. Synops show a low of 15.7°C for the day which makes more sense. Maybe a data entry issue? I have updated the low to what the synops shows, raising the monthly average low by 0.1°.
Jun 1996 - Bizarre issue on the 9th where the high and low entered in the ECCC Archives were actually only for the 6pm to midnight period. The high on the 10th appears to also be incorrect. The true values for these two dates were found in a publication at ECCC (32.5°C and 32.8°C highs, low of 16.2°C on the 9th). These changes raised the average high from 25.1°C to 25.2°C and dropped the average low from 11.9°C to 11.7°C.
