What kind of winter can we expect?

The best outlook indicator is the El Nio Southern Oscillation

Every year climatologists look for 'clues' in the atmosphere about what kind of winter weather Canadians might expect.

The best indicator for early outlooks is the presence of the El Nio Southern Oscillation, which is warmer-than-normal waters in the southern Pacific Ocean that change weather patterns all over the world.

If El Nio is there, the winter here should be milder.

The reverse of this pattern is the La Nia, which can often translate to colder and snowier winters for the West Coast of Canada.

So which is it this year?

It's actually neutral. No pattern one way or the other has been detected, so winter could go one way or the other for us in B.C.
