So far I've recorded a clear and cold -15C as the low temp here in my yard in S. Ajax Zone 6 yard. Normally these type of temps don't hit us until around Jan 10 or so. Having said that our long range is looking above normal with some drying up.

All my protected palms have had only supplemental heat to date for about 2 or 3 nights..

Merry Christmas everyone!!

Palmettoman Z6-Ajax, On

Edmonton city centre zone 3a. Temperature on Dec. 21/08 -31.1* C (NE Edmonton temperature was 2 or 3* colder).

Until winter 2007/2008 Edmonton city centre minimum temperature over the previous 10 years put our zone at a USDA zone 5a. Then we hit -36* C (officially) last winter. City centre ''official'' temps at the time were recorded as -39* C.

Zone 5b,coldest temps in 25 yrs,-5F,-11F,-17F,-18F,4 nights in a row,had already seen -2F,-2F and -4F in December.
What will February bring?

Zone6b, -1F(-18C) last Friday night. Last two winters we saw -2F and 0F so this was pretty normal for this area.

We hit -2f (-19C) in downtown Toronto, zone 6a.
My placenear Kingston (border of 4b and 5a) hit -20f (-29C) coldest in about 4 years, only once in the last 15 years have I recorded colder, -25f (-32C, I think) back in 2003!
So a 'zone' winter, but the real question is, will we get colder this year?

We have at least this winter was -8. What is Zone 9a 😆
