Super rod all over the place until you find a wailmer
If you are talking about Pokemon diamond you must go to the battle area and get a super rod from the fisherman standing next to the walkway. After you have that fish anywhere in the island and you are definitely gonna find a wailmer around lv 40. For Ruby, Sapphire, and Emerald, you can't catch a lv 40 wailmer, but you catch a wailmer at Mossdeep City using a super rod.
You must evolve wailmer/surf and find one on route 129. There are few there. Wailmer will evolve at level 40.
You can capture wailmer in ruby, sapphire and emerald on most routes where water is you can find either by using a rod or by using surf.
Wailmer evolves at Level 40.

You have to find it in the cave

easy, to find a wailmer in Pokemon ranger 2 you need to go back to the place where wailord was kept hostige. go to a place in the ocean where there are two rocks that need Pokemon with a level 4 crush. after you break the rocks, keep proceeding and you will find a wailmer!
the easiest place to catch it is on mossdeep city and use a super rod in the water, you will ALWAYS find a wailmer this way
