Shubenacadie Sam sees his shadow, Shubenacadie, NS, 02 Feb 2020 (Twitter)
The first marmot in North America to make a weather prediction on Groundhog Day was Nova Scotia’s Shubenacadie Sam who saw his shadow early today which means another six weeks of winter.
However, Ontario’s Wiarton Willie and Pennsylvania’s Punxsutawney Phil didn’t see their respective shadows hence an early spring is expected.
So which groundhog do we believe?
The annual tradition originated in Germany and traces its roots to religion rather than science.
Environment Canada notes how data over the last 30 to 40 years shows that the groundhogs have only been correct about 37 percent of the time.
But admittedly, it’s a fun way to mark the midpoint of winter whether or not it wraps up early or drags on into spring.

- Minto area 31
- Greater Moncton Airport 25
- Fredericton area 16
- Saint John Airport 13
- Miramichi 10
- Bathurst 4

The remnants of Tropical Storm Olga were felt across Southern Ontario on the weekend with rainy and windy conditions.
Environment Canada says between 30 and 60 mm of rain fell across the region including the Greater Toronto Area.
Wind gusts were up to 80 km/h in some locations with a peak of 104 km/h recorded at Port Colborne on Lake Erie.
Olga formed in the Gulf of Mexico several days ago and made landfall in Louisiana before quickly churning northward toward the Great Lakes.
Forecasters are calling for more wet weather and cooler conditions by Halloween.
The view from Economy Point, NS, 03 July 2019 (Dearing)
After a cool and wet start to summer, a blast of heat is heading to the Maritime Provinces over the next few days.
Environment Canada has issued heat warnings for most of New Brunswick – excluding the Fundy coast – and western Nova Scotia while other areas under a special weather statement.
A warm, humid air mass is moving into the region today raising daytime temperatures to 30°C or more.
Humidex values near 40 are expected and overnight lows may not fall below 18°C providing little relief from the heat.
Near normal values will return late Saturday as a cold front arrives.
Heat warnings are also in place for parts of Ontario and Quebec where it climbed into the low 30s yesterday.
