Exactly. Of recent years, only 2014 and 2017 were what I would class as ‘bad’. Here at least August 2017 was even a very usable month, it just wasn’t summery apart from the odd day here and there and the BH hot spell. 2018 grew gradually worse as it went on. Last year had fine weather in the first and final third but had a garbage filler. 2016 was very decent here.
Ive always thought that August does its own thing when June and July are either great or terrible.
