May 2007
5.2ºC
St. John's UaDK
It was the coldest month of May on record. The temperature did not rise above 10ºC on 19 days during the month and eight days set new coldest daytime high records. The daily mean temperature was a chilly 5.2ºC, over a full degree colder than the average mean of 6.5ºC (set over seven years from 2000-2006).
20 May 2007
11.7ºC
St. John's UaDK
Finally, a warm record has been set. The overnight low only slipped to 11.7ºC, which was the warmest overnight low ever recorded in the month of May going back to 2000. The high of 20.4ºC was also a new warm record for May 20. However, despite this sudden warm weather, the month of May 2007 is still on track to be the coldest May on record, keeping in line with previous months so far this year.
April 2007
3.3ºC
St. John's UaDK
Another cold weather record. Thanks to a cold north-easterly flow, the month of April was the coldest April recorded at the weather station. Only averaging 3.3ºC this month, the temperature was a full 3.1ºC below the average daytime high for the month of 6.4ºC.
February 2007
-2.5ºC
St. John's UaDK
After a fairly mild January, February turned much colder. It was the coldest month of February on record, a full 2.1ºC below the normal February daytime average of -0.4ºC. The temperature did not rise above 0ºC for 283 consecutive hours between the 4th and 15th of the month.
August 2006
19.6ºC
St. John's UaDK
After an early start to summer, the weather station recorded it's coolest August ever. The previous coolest August was in 2005 when the daytime highs averaged 21.4ºC. This year, the daytime highs averaged a sad 19.6ºC over the whole month, almost two degrees colder than last year.
June 2006
19.0ºC
St. John's UaDK
It was the warmest month of June ever recorded at the weather station. The previous warmest June was in 2000 when the daytime highs averaged 17.7ºC. This year, the daytime highs averaged a wonderful 19.0ºC over the thirty days.
24 June 2006
16.9ºC
St. John's UaDK
A southwesterly flow did not allow the overnight low to drop below 16.9ºC which made it the warmest overnight low ever observed in June since records began in 2000. However, by 23:59 NDT, the temperature had fallen to 16.1ºC, and thus 16.9ºC was not the official low temperature for the day. It was 11ºC warmer than the average low temperature.
25 Feb. 2006
50-60cm
snow
St. John's
An intense low pressure system tracked further west than forecasted bringing intense snow and violent winds to much of eastern Newfoundland. Snowfall totals were close to 60cm and wind gusts were that of hurricane strength. The 57.9cm of snow that fell at St. John's UaDK was a record for a one-day snowfall. The 54.0cm that fell at the airport was 14cm shy of breaking the record set in April 1999.

16 Jan. 2006
10.4ºC
St. John's UaDK
The same cold front did not reach the Avalon peninsula until 23:30. This kept St. John's in the warm sector of the low and the strong south-westerly winds kept the the temperature above 10ºC overnight, only falling to 9ºC at after 09:00. The overnight low temperature was 20ºC above the normal low of -10ºC. By 23:59, the temperature had fallen to 5.1ºC and thus the 10.4ºC was not the official low temperature for the day.
15 Jan. 2006
15.0ºC
St. John's UaDK
This same weather system resulted in a high of 15.0ºC, making it the warmest January day since records began in 2000. The high temperature was 15ºC above the normal high of 0ºC.
15 Jan. 2006
15.7ºC
St. John's Airport (YYT)
Ahead of a sharp cold front, strong south-westerly winds helped to push a warm, tropical air mass ahead of the front. This resulted in a high of 15.7ºC, making it the warmest January day since records began in 1942, beating the old record of 15.2ºC set on 09 January 1979.
08 Oct. 2005
16.8ºC
St. John's UaDK
The overnight low dropped to 16.8ºC making it the warmest overnight low temperature for October since records began in 2000. However the temperature plummeted to 6.6ºC by 23:59 NDT and hence was not the official low for the day.
02 Sep. 2005
19.5ºC
St. John's UaDK
The overnight low dropped to 19.5ºC making it the warmest overnight low of 2005 and the second warmest low temperature since records began in 2000. However the temperature fell to 17.5ºC by 23:59 NDT and hence was not the official low for the day.
23-26 Aug. 2005
130.0mm rain
St. John's UaDK
After a very dry month of August where only 23.1mm of rain fell in the first 22 days of the month, four days of heavy rain resulted in a deluge of 130.0mm. August 24 saw 55.6mm fall which was a record for the day and month for a one day rainfall total.
