july weather in South BC

It has been one of the coolest summer so far. Last year was bad as well.... looks like all the nice warm weather has been shipped up north and back east....... all the predictions have been wrong


I hope the predictions continue to be wrong in the right way!

South BC Summer Forcast

I just went to the weather network and read their summer weather prediction and it is so far off of what is actually happening its laughable. I come here and it seems to be almost spot on. So much for a network with billions of dollars of equipment being able to tell what's going on.

It's been cold for 2 years

Ever since the end if the last big fires Sept. 2018 its been cold and rainy/snowy here in southern bc. I pay attention to the weather and my memory is sharp. 1st July right now, probably 8 degrees and raining all day. It has not been usual weather for the area. It used to be sunny everyday around here this time of year for as long as I can remember.
Something switched that's for sure. We will take it instead of forest fires but what was the deal with those coming on so strong all of a sudden as well? Things are a foot and the earth don't seem to happy anymore, not good.

weather in West Kootenays

It is very cold. April 2 water froze overnight. March on time every spring run-off creek began to run on March 19 every year for the past 40 years. For the past two years, maple buds have frozen on trees thus not producing flowers or seeds. The same happened to mountain ash trees. Both are the major food supply for birds. deer eat mountain ash berries in winter. It is too cold. way too cold. Heavy snow in March in 2019. Snowstorm on March 24, 2020, at mid to north end of Kootenay Lake. This may be the new normal, we have lost one month Spring is much later now, even the migratory birds cannot adjust because it happened so fast. There is an ice-cold wind outside, when will it warm up? Time to move somewhere where it is warmer and the climate is milder

Planting reminders

I used to get planting reminders. I have recently viewed a number of areas on the website over the last couple of weeks. Now all I get are the store, ads and stuff I dont need. Why are the reminder plantings emails not coming anymore...I use it all year long as my only guide.

Long range forcast S. B.C.

Long range for cast has been pretty good. Seems out by 1-2wk.s, which is not too uncommon. The forcasted pattern is what I use, then I combine full moon cycle to fit the pattern. In my experiance I find that the wk of the full moon (moon full mid wk) is when I expect a greater weather change.
This I always consider along with TOFA. This has severed me well in planning.
Those who expect accurate daily predictions 3 months advance are not being sensible. I find the forcast pattern far more useful than any local 2wk. Forcast . Even local short range daily forcast can be fickle, but they too are still in my tool kit. Thank you TOFA


What the last guy said.

Jan 9-14 forecast

"Jan 9-14 Rainy periods, turning mild coast" Lol! Waaaay off base!! Hit with a huge blizzard in the Fraser valley, Chilliwack hit hard. Plus strong Arctic cold air mass settling in the valley and coast!! We're digging out of this snow, highways closed, accidents everywhere! How do you do your forecasts? On a dartboard??

Temperature and rainfall

For S.Smith, rheumatism pains due to wet weather. Montreal is dry but southern BC is wet.
I always check your long range forecast for long term planning. Hope next year and every year after that, BC
will be spared forest fires, so tragic.
