Swarm occasionally, in front of Fuego Ironworks.
During a swarm in Lake Valor. Swarms change daily and you can look up what the current Swarm Pokemon is at Dawn's or Lucas's sister in Sandgem Town (depending on which gender you chose).
JesseTheEternal- No, there is a big list of Pokemon that can appear however. I don't have it currently.
Everyday there will be a random swarm of Pokemon in a certain route. To find out about this swarm, talk to Lucas'/Dawn's sister in Sandgem Town in one of the houses. She'll notify you which swarm of Pokemon is there today and where to go to find them. If she tells you there's a swarm of Absol in Route 213, travel to that route and walk around. The chances of finding an Absol is 40% when there is a swarm.
Nosepass is a swarm Pokemon on Pokemon diamond
Have you talked to the gir every day? The swarm should change. :)
Swarm in Fuego Ironworks

A swarm, in Pokemon terminology, is a group of unobtainable, or rare Pokemon in a certain area, in bulk. These groups of Pokemon appear randomly every day. In Pokemon Diamond you can determine the swarm of the day by going to the house south of Rowan's lab in Sandgem town, the girl in there will tell you where the swarm is, and what Pokemon it is consisted of. For Swarms to appear you must already have the National Dex, which is given to you after you have seen every Pokemon in the region, and talk to the Professor.
In Pokemon Diamond and Pearl, Phanpy swarms on Route 207.
