Having done a decent amount of diving in the puget sound, no way the water is 68.
Mid 50s is tops, it can get down in the 40s as well.
Well, most of the triathlons are done in the lakes. The
Kirkland triathlon states "mid 70's". Not sure how accurate that is. Hopefully, we'll get a heat wave that week.
If you're diving into water in the 40's.... brrrr!!
