Still smoky and warm on the

Still smoky and warm on the coast, we really need some rain to clear this out. Please, can somebody order some rain?!

Not accurate at all

We have smoke from the wildfires and while that has cooled it down here in the Lower Mainland not one isolated shower or generally cool, it's quite muggy and smoky at night not comfy at all. Guess we'll see if that changes

The temps are predicted high

The temps are predicted high but not nearly as warm due to cloud cover from smoke but it's definitely not hot

Very accurate so far for summer!!

So far the FA has been very accurate for summer 2018 in the region! Although I’m impressed with how accurate it’s been I’m hoping the predictions for the rest of the summer are wrong because I want warmer weather!


I’m with ya Amanda!! Was shocked how accurate it was but, also hoping wrong for August cause I have lots of camping in mind haha

Weather predictions for May on the South Coast

They predicted for May an average temperature 11°C and rainfall of 30 mm, 20mm below average. We've had 1.5 mm and temperatures not seen before all well above average in the mid to high 20's. It's been unprecedented hot, unusually humid summer weather and no rain in what use to be the wet and dismal month of May.

south central bc weather

this year holds the fourth place record for most snow fall recorded in the kamloops to williams lake bc region.
here's hoping the almanac is off for the spring and we get slightly warmer weather.


Extremely cold in the West Kootenays feels like -20 at times, in mid- to the third week of February

February weather in bc is not accurate for farmers almanac

Lots more snow and very cold in Southern BC for February

Not very accurate this year

Previously we were able to buy the regional forecast for SW BC for $4.95. I understand there is a new system. Even if it’s the same price I don’t need the entire book, and this year the forecast is not very accurate. Today is the week ending April 7 and we were supposed have sunny and cool weather. Instead in Vancouver it rained every day and only on Friday did the sun peek out for a few hours. Also February had more snow than December. Maybe modeling the weather for the late 1960’s, when the solar minimum was comparable to now, would be helpful.
