For a glove to breathe, there needs to be more vapor pressure on the side with your skin. If it's cold and dry outside, the pressure is high so the sweat gets right through the membrane. If it's cold and wet, there's still pressure so the sweat moves through (though your hands probably won't sweat much to begin with). For warmer weather where the temperature differential between the inside and outside of the gloves is not so great, there's not much vapor pressure to move the sweat through -- don't forget that wet on the outside means 100% relative humidity.

You might try a lightweight noninsulated glove designed for spring/summer skiing. But I still think your hands will be wet from sweat. I'm a Gore-Tex product tester and I get to work with stuff (including gloves) that is often nicer than anything you can buy. But without enough vapor pressure, you'll eventually overwhelm any membrane -- even bare skin if it's warm enough.

I'd be more inclined to go light and water resistant for your application.
