I'm beginning to think so.
It's now mid May and people are still in boots and coats.
Even if we were to get 3 months of sizzling sun in June July and August (and maybe 2 weeks Sept) that's only 14 weeks. And we all know June and July are often washouts.
This season I have bought 2 pairs summer trousers and 2 T-shirt type tops and not worn either yet.
