According to my weather book, 30C occurred on the 16th of April 1949 in
London.

29.4C at Camden Square according to Trevor Harley's excellent site:

The discrepancy is probably a difference in rounding when converting
from Fahrenheit (which I suspect the original reading was in) to
Celsius.

33C occurred on the 22nd May 1922, again in London.

The site above quotes 30.6, 32.8, 31.7, and 32.2 for the 21st-24th at
Camden.

The highest ever June temperature (and again for London) was 35.5C and
occurred on the 29th June 1957.

Camden Square again. The site above gives 35.6C, and says it is the
equal highest for June. The joint record holder is Mayflower Park in
Southampton on the 28 June, 1976.


The exact details of where in London these temperatures were recorded is not
stated.

See above, I would guess that Camden Square was a rather sheltered site
that would have benefited from its inner city location. I don't think
that recordings are still being made there, but I could be wrong.
