How often is July the coldest summer month where you live (January for you southerners)? (warmest, records)

[Glacierx]

Given the fact that July was the coldest month this summer in may places including Windsor, Ontario, I got to wondering how often this occurs. I'm talking in terms of the mean temperature.

Here is a summary of a few places with long term records:

Toronto (records began in 1840):

88% for June
2.3% for July (4 times in 173 years with the last occurrence in 1976)
9.3% for August

Calgary (records back to 1885)
83% for June
3.2% for July (4 times in 126 years with the last occurrence in 1986)
13.5% for August

Vancouver (records back to 1896)
97% for June
0.85% for July (1 time in 117 years with that one occurrence happening in 1897)
13.5% for August

Tatlayoko Lake, BC (records back to 1930)
90% for June
0% for July (Has never happened in 81 years of records)
10% for August

Agassiz, BC (records back to 1893)
92% for June
3.4% for July (4 times in 118 years with the last occurrence in 1986... sounds similar to Calgary even though this place is close to Vancouver)
5.1% for August

Kamloops, BC (records back to 1891)
81% for June
3.3% for July (4 times in 120 years with the last occurrence in 1986. There is that 1986 again.)
14.9% for August

I don't have any stats, but July 2012 was cold for the UK!

July has been the coldest month of the summer 15 times in the past 350 years in England, but only four times in the past 100 years and not at all since 1965. In 1802 June, August and September were all warmer than July, making it only the fourth-warmest month for the only time.

Re. July 2012, it was 2C warmer than June the same year, though 1.1C cooler than the August.

In Southern California:

Temperatures don't peak until late August or early September.

Early July feels more like early October here.

And June temperatures are comparable to late October or early November.

I'd say it's pretty often.

Twice in the last 18 years

It occasionally happens that August is hotter than July (including this year). But June warmer than July is unusual — the first half of June averages well below typical "summer weather". Happened in 1976, with the warmest June on record and a slightly below average July. But August was still slightly cooler than July; you'd need two unlikely events to occur at once, with one of them much more unlikely.

In Amherst, only summer I found that it happened was 1895, that July was the coldest on record and June 2°F above normal. Must have felt strange, felt like the start of a warm summer... then reversed.

[dunno what to put here]

August warmer than July isn't uncommon, but June being warmer than both is rather rare.

[Donar]

July as the coldest summer month is supringsingly common here. Happened six times in the last 20 years: 2011, 2003, 2002, 2000, 1998 and 1996

[Jakobsli]

Extremely rare here.
It happened in 1969 (June mean 15c, July mean 14.2c and Aug mean 17.1c)

August warmer than July is not unusual (as this year), but June is usually the coldest summer month here.

Can't find any years with December as warmest. February is nearly always the warmest, other than Occasional years where March is warmest.
