I’m going to get my ‘summer haircut’ soon. I’ll also have a ‘summer beard’ too.
It just means that both will be shorter and a bit easier to manage. It’s partly to remove any extra and unnecessary resistance I create in the water with all that extra hair getting in the way. But to be honest it’s mainly just about making it easier to manage if I’m in and out of pools and lakes more regularly.
Here’s as an example as to why it’s necessary.
This morning’s hair – mad professor!
I went for a swim late last night, so went to bed before it had fully dried, then when I got up this morning to swim again it looked like that!
Office hair – a bit more normal
I didn’t actually do anything with it, just went to the pool and swam it into normality. I did spend a little bit of time after the swim trying to look less Yeti like for the office though!
Anyway, there will soon be less of it and I will hardly have to spend any time worrying about it.

I would love to have enough hair to create some sort of resistance…
