It was a beautiful day to get out of the city, so gabriel_le and I took the bike up to the cottage today. Headed up around noon, spent the afternoon there, then back home for early evening, since she has more meals to prepare. The lake surprised me with how warm it was, considering I thought June had been chilly -- I dove in, without checking the temperature, and didn't scream when I surfaced. I swam around for a couple minutes, climbed out, stood for a couple minutes, then dove back in and swam for a few more minutes before getting out. It was, for me, decent swimming temperature -- 5-15 minutes in water ok -- but not warm enough for lounging (30-90 minutes). Of course, the more water-loving would probably fine it nicer.
