High (rounded down): # of days
That's 122 (66%) days where we got to at least 15 degrees, and that's including nearly 2 months of spring and over a month of fall.
Even March and April were damn fine for spring. You really have to go back to January/early February to find actual "cold" weather. Other than a single aberrant -0.5 high, we have not seen a high below freezing since February 22nd. That's over 8 months of above-freezing days, and it just keeps going. We could conceivably make it through much of November on the plus side.
An amazing year for a supposedly cold city. Mind you, it only got above 30 once this year, for all you ectotherms out there.
I'll bite the bait, hehe. I do see what you are saying, but the term "cold" is very relative, and comparing Calgary's weather to San Diego is a huge stretch, a much better comparison with our southern neighbor to Calgary would be Denver. While Denver is much warmer in the summer than Calgary (on average) it experiences similar weather trends, quick drops and rises in temperature, late and early snows / cold snaps, warm down sloping winds breaking apart the winter, and a large diurnal gap in overnight / afternoon temperatures.
Compared to Calgary, Vancouver would be a far better Canadian comparison to San Diego from May 1st to Oct 31st. (Again, even I think this is still a big stretch)
Here is the data for Vancouver in relation to the stats you have for Calgary Above:
So Vancouver has 152 days above 15 during this stretch, giving 82.6%. Much higher than Calgary. Also, I personally find having 28 days that do not reach 10 degrees between May and October to be very cool (especially when compared to Vancouver's 1).
Then one one compares low temps during this 6 month trend, Vancouver is far more mild than Calgary.
Calgary Lows (again, grouped in 5 degree intervals going up from the temperature shown):
So while Vancouver had 0 nights below freezing during this 6 months Calgary had 25 nights below freezing (far more like Denver) and while Vancouver had 132 nights stay above 10, Calgary only had 40 nights do so.
Then, when compared to Kamloops over this period, one would definetely find Calgary "Cool" on average in the summer
That is 88.5% of the days above 15, and 120 days above 20, with 37 of those days above 30.
Now, here are the 3 cities listed above highs, lows, precip & snow averaged throughout that 6 months period for this year:
Calgary, H 17.2
, L 5.8,
P 354.4mm, Snow 28.2cm
Vancouver, H 18.7
, L 11.3,
P 412.9mm, Snow 0
Kamloops, H 23.4
, L 9.9,
P 180.5mm, Snow 0
So for me, personally, I find Kamloops to be the most comfortable city out of those three, it by far has the warmest average high and the lowest precipitation. Both Vancouver and Kamloops recorded no snow during this time, and Vancouver had the warmest low with no frost / freezes.
Hence I would find Vancouver's climate far more like San Diego than Calgary's.
Again, I don't want to dump on Calgary, but please don't compare yourself to San Diego, Denver is far more fitting for a comparison. Also, when one brings up such weather stats I just cant help but compare it with the area I live in, again, we are all weather nuts on this thread!
And, just for fun, here is Abbotsford's highs for this 6 month period, being that it is the closest weather station to where I live.
So that is no days not reaching 10 during this 6 months, and 93 days above 20 with a decent 10 above 30.
