An average maximum of 23C means that the cooler days can often be around 18-19C and even 16C exceptionally.
An average maximum of 27C means that the cooler days are around 22-23C and days with highs below 20C are very rare.
I have been watching weather forecasts intently in Toronto from about 1995 until 2010.
Except our hottest summers,
we ALWAYS get at least one 17 C/63 F afternoon occuring mid-summer (late-Jun to mid-Aug)
usually very windy and/or very cloudy too.
My best guess is we average 3-5 mid-summer afternoons with highs under 20 C/68 F.
I think Toronto's summer temperatures are more unstable than London's;
longer spells of consistently warm-to-hot weather as well as long cool (< 24 C) spells.
*I hate cool summer days, so it's always easy for me to remember when it happens.

Usually just in June, much rarer to see them in July and August, the past 2 years atleast.

Hows summer in Newcastle?
I think most people don't mind if one or two days that aren't warm.
I hated the weather so much, summer was my "compensation" for the rest of the year and every day mattered.
Summers in Newcastle, Australia are generally superb.
Since mid-December...
Mornings below 16 C/60 F are uncommon; typical sunrise is 18-20 C (65-69 F)
Afternoons below 24 C/75 F are also uncommon; typical afternoon is 26-31 C (78-88 F)
Newcastle summer is like consistently getting the better 2/3rds of Toronto summer weather...
except intermittent, rare hotter days are a lot hotter and dryer; "scorching" is a fitting term.

I agree, most summer days in Toronto are plently warm enough,
same goes for Ottawa and Montreal too.
Isn't Newcastle's climate very similar to Sydney?, just a degree or two warmer,
or am I wrong?
The point was to compare years with our cooler summer weather seasons with London's normal summer weather seasons.
About 1-in-5 years we have what Toronto residents call "A Year Without Summer"
I want to know if patterns like this is normal in London: (or is this still cooler than London's typical summer?)
- 2 to 3 weeks with highs below 21 C/70 F with the bulk of days between 17-19 C and a few 15 C days in the middle of summer
interupted only by 1-4 days with highs between 22-26 C... then back to the dominant 17-19 C daytime high pattern
The lowest average July high at Pearson Airport (on record) was in 1992 - 22.9°c. Everyday was above 20°c except for four days (15.4°c, 19°c, 19.3°c, 19.5°c).
that same month in my town was still a little a bit above London's average.
This station (Toronto City Center Airport) is on an island that tends to be 1-3°c cooler/more humid than the rest of Toronto because of the great lakes cooling effect. Inland stations are usually warmer:

For myself, most sunsets in Toronto summer felt cool and this annoyed me.
Then our cooler days felt like sunset or nighttime all day long.
Toronto heatwaves accounted for three-quarters of my "very happy days" in summer
and the rest was a small portion of just above-seasonal days. (28-29 C days and/or 19+ C lows)
So roughly 10 to 60 days in summer were "very happy days" in Toronto.
It's not always warmer, but generally yes.
I think Newcastle also gets fewer hours of overcast than Sydney.
This year we are in a drier pattern (El Nino?)
and sunshine & rain patterns feels similar to when I lived in Western Australia.

Sun must feel good though eh, compared to Canada.
I just feel more energized and warmer if the UV is higher, love it.
For me I didn't really feel much of a difference between uv index of 9 compared to 11 closer to the equator.
But I assume if it is at 14 like where you are then it really makes a difference from 9.
That is one of the big things I hate about winter, sun is much too weak and I don't have much energy. Not to mention also have to take vitamin D pills.
