So only 12.2 is needed for the last 2 days (including today).
July CET days that low or lower have only occurred 9 times since 1980, mostly in clusters in just 4 years, the lowest being 2 x 11.1°C days in 1993. The last was in 1997.
Regardless of the rarity of such low July temperatures, I suspect we are looking some 5 degrees higher for the last two days, heading towards a finish of about 18.3
A 15.7 August would be adequate for a 17 summer mean.
