It doesn't seem to make any difference. Water just won't
mix with the cement and a reasonably fresh glue layer is
plenty sticky in spite of a little water.
I've only changed a flat in the rain once, on a club ride.
No more or less miserable than any other flat in the rain.
Riding to any available shelter is a big difference from
just standing in the rain.
Today for example I finished errands and rode another mile
or so before returning to the shop to change indoors out of
the sleet. I'd rather ride a flat tubular (leaning back,
taking some pressure off the front wheel) a while than deal
with it by the side of the road.
Rainy days sure do disturb the normally compacted crud in
the pavement. Every piece it seems washes sharp side up. . .
