Pools are abundant and offer relief to warm and weary folks. I have not been swimming yet but I have been using my sunblock and staying in every bit of shade I can find.
The challenge of putting on the sunblock for me though is always having streaks of it that I have missed and not rubbed in enough on my face. I tend to realize it when a stranger gives me a second glance. Thus it is helpful to have a small mirror in my bag to address the issue. I have a few extras for others.
