Anyone else get one from wind alone, no sun, no cold, just wind?

Great question, and you are not alone with this. Catching the trigger early is where most of the difference comes from.

Reapplying after eating is my weak spot, working on it.

This is so me. You are definitely not alone with it.

Yes, every spring on the bike trail I get one after a windy ride even when it's overcast and mild, so you're definitely not imagining it. I've started keeping my lips covered on gusty days and it seems to help a bit, but honestly the wind still gets me sometimes.

Yes, absolutely, a windy bike ride on an overcast day is what set off my last one and I was so confused because I'd done everything else right. I think the wind just dries the lips out so fast that the skin cracks a little and that's all it takes for me, sadly.

Yes, absolutely, a windy day on the ridge with full cloud cover got me once and I was so confused because I thought I'd covered all my bases. I think the drying out is the real trigger for me, not the temperature.

Protecting my lips before skiing changed everything for me.
