Weather Stations In BC (Photos)

The interesting thing about Peachland is that it has the warmest winters anywhere in the Okanagan valley, even warmer than Osoyoos. This is likely due to the moderate effect of Okanagan Lake.

Considering the average Tmin, the Peachland weather station must be at the top of a hill.

Average Tmin for this month so far:

Kelowna Aiport: 11.0C
Pencticton: 12.9C
Kelowna UBCO: 13.6C
Summerland: 15.2C
Peachland: 17.3C

I don't think the station is overheating because Tmax are consistent.

Wrong... it's in the valley bottom, but the constant wind off the lake keeps the overnight temperatures up.

The Yukon has been gutted of weather stations over the past 20 years or so such that the only ones left tend to be at airports. There are FEWER than 20 weather stations in the entire territory now, but at least they are all really well situated as far as I can tell.

Old Crow (fly-in community only, and the most northern community in the Yukon... also, no alcohol allowed)

Whitehorse (interesting how there's no fence around the station):

Watson Lake (not exactly sure the location here):

Burwash Landing:

Haines Junction doesn't have the station at the airport for some reason:

Teslin (this is just a guess on my part):

RIP Gold River (1966 to 2016)

Not a very good location anyway.

BC's south easternmost weather station... Baynes Lake Kootenay River...

Revelstoke, a good one.

Too much pavement behind it Sheriff.

The clearance around the station is very good and the concrete surfaces are relatively distant. This is a good station.

I agree that it's a good one, however, answer me this, Rocket Scientist: Why does Revelstoke have two stations at the airport (one by EC and one by Nav Canada) with the temperatures often being up to 5 degrees apart on hot days.

example 1: EC station = 34.6C on July 13th, 2018; Nav Canada = 31.8C

example 2: EC = 37.1C on July 8th, 2017; Nav Canada = 32.6!!!

EDIT: Interestingly enough, the hourly data for the EC station peaked at 32.9C, so maybe just a faulty thermometer by EC!

I've often noticed that Nav Canada stations seems to have a cold bias. I notice it a lot with nighttime temperatures, as well (actually, moreso than daytime).

Huh, EC's rules...

Let's have a look at the hourly data:

On July 8, 2017:

Time - Revelstoke A - Revelstoke Airport Auto (difference)

12:00: 20.7 - 26.4 (+5.7)
01:00: 19.5 - 27.6 (+8.1)
02:00: 23.5 - 28.9 (+5.4)
03:00: 23.9 - 29.1 (+5.2)
04:00: 24.0 - 31.7 (+7.7)
05:00: 31.2 - 32.9 (+0.7)
06:00: 31.6 - 32.6 (+1.0)
07:00: 28.4 - 29.5 (+1.1)
TMax: 32.6 - 37.1 (+4.5)

Since the 2 stations are supposed to be almost at the same place, the readings are totally inconsistent.
Furthermore, the Tmax of the 2nd station is 4.2C higher than the hourly Tmax, which is highly unlikely and suspicious.
And a 4.5C difference between the 2 Tmax is impossible.

On July 13, 2018:

Time - Revelstoke A - Revelstoke Airport Auto (difference)

12:00: 22.0 - 24.0 (+2.0)
01:00: 26.1 - 28.8 (+2.7)
02:00: 31.6 - 31.4 (-0.2)
03:00: 30.4 - 31.2 (+0.8)
04:00: 26.5 - 30.4 (+3.9)
05:00: 29.0 - 29.8 (+0.8)
06:00: 27.4 - 28.0 (+0.6)
07:00: 25.6 - 26.7 (+1.1)
Tmax: 31.8 - 34.6 (+2.8)

The readings are more close but still very different at certain hours (1:00, 4:00).
The Tmax of the 2nd station is 3.2C higher than the hourly Tmax, still too much...
A difference of 2.8C between the 2 Tmax is here again highly unlikely.


As Abby_wx said, there's a looooot of problems with some data, especially since 2013 or so (when NAVCAN replaced many EC stations).
I've noticed a lot of incoherences with YVR station when the sky is clear.
For example, I don't believe in the June record on June 30, 2013 (!). The hourly max was 26.1C and the Tmax was supposedly 31.2C!

In short, this is a real nightmare...

I've often noticed that Nav Canada stations seems to have a cold bias. I notice it a lot with nighttime temperatures, as well (actually, moreso than daytime).

You are so right. I just ran a quick run at 2019 data for 7 airports in BC that have both stations.

In 100% of them, the cold bias exists at night. The daytime is less so, but look at Kamloops! Dease lake has an interesting trend!
