If you have been following local news, you’ve no doubt heard about the unusual visitors that have made their way into our waters; a few “Man ‘o War” have been spotted at local beaches. Some experts believe this could be a result of the warmer than normal water temperatures. Anecdotally, the water does seem to be quite warm for early August, just ask local beachgoers.
Just outside the Halifax Harbour, the sea surface temperate is 18.8 degrees, while the normal August sea surface temperature is only 17.0 A two degree deviation from a normal temperature is significant!
Now, I decided to look elsewhere and my findings are interesting. Have a look:
NEW BRUNSWICK: August 10 2017 August Average Temp.
Campbellton 12.2 13.3
Saint John 12.8 13.3
Bathurst 13.3 14.7
Shediac 16.7 16.9
Digby 13.3 13.9
Parrsboro 17.2 17.0
Lunenburg 18.3 16.5
Halifax 18.8 17.0
Glace Bay 20.0 17.7
PRINCE EDWARD ISLAND
Summerside 18.9 18.1
Charlottetown 18.9 18.3
I was surprised to see how the sea surface temperatures around New Brunswick were all below average, while, with very few exceptions, the water temps around Nova Scotia and Prince Edward Island were above.
The greatest deviation was in the waters off Glace Bay NS with a difference of 2.3 degrees.
Warmer than normal water temperature have the potential to maintain the energy in approaching tropical waves. We’ll keep an eye on those as they develop.
