Have you ever wondered which place in the province is your city's doppelganger? Let's just look at daily low temperatures and see which other place or places in the province have 50/50 odds of being hotter or colder than your city.

Example #1: Pitt Meadows has a 99.8% chance of being warmer than Yoho National Park, so clearly Pitt Medows is the warmer place. At the other extreme end, Pitt Meadows only has a 12% chance of being warmer than White Rock, so clearly White Rock is warmer (in the mornings anyway).

BUT, compared to Malahat, the odds are almost 50/50 with Malahat being warmer 49.6% of the time and Pitt Meadows being warmer 50.4% of the time (ignoring tied days). Therefore, Pitt Meadow's doppelganger is Malahat.The reverse is also true for Malahat, but this is not always the case.

Some other interesting ones: Nanaimo's doppelganger is Lytton, but Lytton's doppelganger is Sandspit. This happens because Lytton and Nanaimo are about 1% off verses a 0.5% difference between Lytton and Sandspit.

Victoria's doppelganger is also Sandspit.

Osoyoos => Port Hardy
Abbotsford <=> Hope
Cranbrook <=> Princeton
Duncan => Masset
Williams Lake => Smithers,
Puntzi Mountain <=> Dease Lake
Lillooet => Powell River
etc.

Some places have no doppelganger because they do not have anyone who is at least 48/52% against.

One is Saturna Island which is warmer than the 2nd warmest spot (White Rock) 65% of the time.

Another is Clearwater, where its closest comparison is Merritt, and even then it's Merritt 60% and Clearwater 40%. Against all other places in BC against Clearwater, he place is far more warmer than Clearwater or far colder.

The last place with no doppelganger is Vancouver (YVR) with its nearest comparison being West Van (Vancouver is warmer 56% of the time verses 44%.

West Van's doppelganger is Estevan Point.

How many heat warnings would there be across Canada if the entire nation used the same heat warning threshold as Vancouver or Abbotsford?

Interesting analysis Glace l just noticed this today, appers to be some rather suspicious towns or cities in that list.
Perhaps some fudging of the numbers maybe involved. my thoughts for Chilliwack is a 100% chance of being nobody's uncle Glace.

On January 15th, 2020 at 8 am the conditions at the Puntzi airport were calm with a temperature of -48.5C. The relative humidity was 51% and the dewpoint was -54.3C.

I had known this before, I just noticed that the forestry station at Nazko was even colder that day. An hour earlier at 7 am in Nazko, west of Quesnel, the temperature was -49.0C with a relative humidity of 43%. That equates to a dewpoint of -56.0C. I "dew" believe that this is the lowest dewpoint ever recorded in BC (although, forestry stations didn't record this until the past 20 years).

Wow, I hadn't noticed that. By my count, these are the hottest months ever recorded in BC (and probably Canada)...

Thanks for the info.

Is July 1906 the warmest month ever recorded for the Lower Mainland? I see Agassiz had an average high of 30.5c that month!

Scratch that post from a few days ago! August 1898 may have been the hottest month ever recorded in Canada -- with an average high of 36.5c in Spences Bridge. 8 days were missing from the monthly data though.

August 1898 was also documented to have been a scorcher in interior Oregon.
https://portland.daveknows.org/2011/08/ ... in-oregon/

A heat wave hit the Northwest’s Inland Empire and Northeastern Oregon during the summer of 1898. The all-time record high was surpassed by 5 degrees in Walla Walla, Washington, when the thermometer reached 113. But the hottest spot on August 10, 1898 was Pendleton, Oregon, where the thermometer topped out at 119 degrees Fahrenheit (Morning Oregonian, 11-August-1898).

"PENDLETON, Or., Aug. 10. – Today was the hottest in the history of Pendleton. At 11 o’clock the thermometer stood at 111 degrees. In the afternoon it reached 119 degrees at the the voluntary observer’s office. Other thermometers about town read from 114 to 123 degrees. Some attribute 2 or 3 degrees of the heat to the fires in the wheat fields four miles east of the city.

Business was quiet and people haunted cool places.

The woolen mills shut down in the middle of the afternoon on account of the heat. There were no prostrations in the city, but a number of horses and men were overcome in the wheat fields."

Scratch this also.

Agassiz had an average high of 30.7c in August 1897, and an average high of 31.3c in August 1898.

Perhaps August 1898 in Agassiz was the warmest month ever recorded for any station in the Lower Mainland.

Almost certainly wrong. The Agassiz data from the 1800s is highly suspicious. The high in Chilliwack on Aug 1898 was just 25.3C. The warmest month there was July 1958 (same as Lillooet) with an average high of 28.8. July 1906 averaged 27.3C, good for 4th hottest on record.

How about August 1898 in Spence's bridge? Good enough for warmest month record in Canada?

The reports from Oregon (east of the Cascades) that month certainly lend credence to the observed temps.

I think this is using the Nav Canada station for Lytton... I'll have to change this later because the 3 to 5 pm records would be higher than shown here..
