Canada is on track to have the warmest year on record - if La Nina doesn't blow it.
The record was set in 1998 when temperatures were almost 2.5 degrees higher than normal for the whole year.
Environment Canada's David Phillips says this year has been hotter than usual, and the trend will continue in early fall - at least in the eastern half of the country.
The senior climatologist says from January to July it's been 3.5 degrees warmer than normal.
Phillips says the stretch from Manitoba to Newfoundland, and most of the north, will be warmer than usual in September.
But in the West it will be either normal or cooler than what's usually seen in September, and cooler than usual into October and November because of La Nina.
The weather phenomenon, which developed in July as the waters of the central Pacific Ocean cooled, is expected to last through the winter.
