Any weather is swimming weather.

I like that our dog walker Mary Ann lets me go swimming when she takes me & Nestle out during the week, even if it’s chilly out.  There’s nothing weird about that.  Do they close the creek in the wintertime?  No.  And what if Michael Phelps’s parents told him he couldn’t go swimming when the temperature dropped below 75?  There’d be no Subway sandwich endorsement, that’s what.
