| Leaves more or less dry. Any moisture present dilutes the glyphosate more. If there are effects on the leaf uptake of glyphosate from rain history, I've not heard of it, but there might be depending on how much rain. My guess is that light rain might make the leaf take in glyphosate quicker while really soaked leaves might not take up glyphosate at all. But I don't know, haven't experimented after a rain, the ground has been too wet for the spraying equipment. It wrecks too much crop loss getting the spray tractor dug out of the swamps.
