sometimes you take what is said here way to literally. Like, "back broken" is not a metrological term, I am pretty sure everyone here is aware of that. and I am pretty sure that 99% of the posters here understand that since it is mid-August, there are likely to be some hot days before the end of the year.
now my interpretation of back broken means that MOST of the HHH days are behind us, with some cooler (no DIT, I am not forecasting 30's) days and nights. and that interpretation also means that YES, I expect some hot days too.
Like you said, it is all very subjective
