If I had to group the summers over the last 10 years into tiers, then this is what I would choose.
The god tier
2018, 2022 (classic summers and the best ones since 1995)
The top tier
2013, 2014 (decent summers with plenty of warmth and sunshine)
The medium tier
2016, 2017, 2019 (nothing to write home about, but not particularly bad either)
The low tier
2020, 2021 (had their moments, but poor overall)
The best confined to the bin tier
2015 (apart from one hot day, it was a poor summer)
