ST. JOHN'S ON PACE FOR WARMEST YEAR ON RECORD?
November 1, 2012 3:23 PM
A record Spring, Summer & now into Fall, 2012 looks likely to finish among the warmest ever at YYT.
Welcome to November! As I mentioned in the last post, October was a warm
one right across the Province.

So how warm was October in NL?
October Monthly Average Mean Temps
Lab City: 2.7° warmer than normal.
HV-GB: 2.4° warmer than normal.
Deer Lake: 2.7° warmer than normal.
Gander: 2.5° warmer than normal.
St. John's: 2.4° warmer than normal.
With an average mean of 9.3°, this marks the 3rd warmest October on record
at YYT (since 1942) St. John's.
It's really been quite a run over the past 10 months here in St. John's.
-Warmest April ever recorded, all the way back to the 1870's.
-Warmest July/August combo in almost 30 years (1984)
-Warmest September ever at YYT.
-The most 20° degree days ever recorded in one year at YYT.
-The 2nd warmest April-September, second only to 1999.
-And now the 3rd warmest October at YYT.
Other than June, which was below normal and March which was average, the
past 8 of 10 months have all been well above normal in St. John's. In fact,
through 10 months of the year, we are currently running nearly 1.9° degrees warmer
than normal. With November & December both looking warmer than normal, could
we be looking at the warmest year on record at YYT?
WARMEST YEARS AT YYT (since 1942)
1999- Avg High: 10.9° & Avg Mean: 6.6°
2010- Avg High: 9.7° & Avg Mean: 6.5°
2006- Avg High: 10.0° & Avg Mean: 6.4°
1951- Avg High: 10.1° & Avg Mean: 6.1°
1981- Avg High: 9.6° & Avg Mean: 5.9°
2000- Avg High: 9.9° & Avg Mean: 5.8°
(1971-2000 Avg High: 8.7° & Avg Mean: 4.7°)
As you can see, there have only been 3 years with average high's over 10°
and 4 years with average mean's over 6° at YYT. This year easily could be
another. If November and December finish with just AVERAGE temperatures, 2012
would finish with an Average High of 10.2° and an Average Mean of 6.3°. With
November & December looking warm, it certainly looks like we'll be right
there in the top 5 warmest years on record. Stay tuned!
