Dunno why but I don't think Rinse Off should be weak in the sun. I imagine in immense heat, getting a refreshing water splash would feel amazing.
Hear me out:
No Weather: 50%
In Rain: 66%
In Sun: 66%, strips water type or fire (if it has) for turn and becomes normal akin to roost.
In Sand: 33%, changes water type to rock or ground with 50% chance of each
In Hail: 25%, freezes user. Ice types using this get 66% healing.
This would be a bit extreme, but Hail would be a way to discourage extreme bulky water spam. Plus it gives Hail a niche.
Of course, this is likely too extreme, but it could mean Sun teams could benefit from defensive water types being present.
