Thank you both for your replies. I guess if it was a hot day out, 70s would be a decent temp. Tri Girl, thanks for sharing your experience because it brings up a good point - it really depends on the winter we had and so far it's still winter here. I had ice on my windshield yesterday, so it's hard to imagine the lakes being very warm any time soon. Maybe I'll check out the sales and get a wet suit just in case. At least I could use it for training while we wait for summer.

Thanks again, I appreciate both of your replies - makes me feel better if I have some idea of what to expect.
