Well, Wailord from the outside seems to be one of those " Boosted STAB, Okay, that's nice. " kind of pokemon, but in the rain, his boosted STAB helps him become something that every whale wants to be..... Read on.
Special:
Wailord (M) @ Choice Scarf
Trait: Water Veil
EVs: 4 HP / 252 SAtk / 252 Spd
Timid Nature (+Spd, -Atk) or Modest Nature (+SAtk, -Atk)
- Water Spout
- Ice Beam
- Surf
- Hidden Power [Bug]
I believe Trachy has given a set very similar to this one, for standard use, and later said " Wailord can't play Kyogre ".
Well, in the rain, he can.
Water Spout is what you're going to use, the rest are fillers, that's it.
Crazy high power, STAB boost, Rain boost!!
And yeah, that's pretty much it. If you take a major blow, start using Surf, which can be replaced with Hydro Pump.
Ice Beam is for the chance of dragons coming along and screwing you.

Wailord (M) @ Chesto Berry
Trait: Water Veil
EVs: 252 HP / 252 SAtk / 4 SDef
Modest Nature (+SAtk, -Atk)
- Rest
- Ice Beam
- Surf
- Hidden Power [Bug]
This was just a filler set, the other one is way better.
Overall, Wailord can see some great use in his own tier, and maybe even UU, if you're lucky.
Rating for the rain - 6.5/10
