He's where you left him in the Weather Tower, in the top floor in the top left corner. He'll tell you that there's some strange drought on a certain route. Fly to the route he tells you and search in the grass there to find Groudon.
The weatherman is in Route 119. He is inside the weather institute west of the bridge in Route 119.
If there is a Drought in a Route on Pokemon Emerald it means Terra Cave has appeared in that Route. Terra Cave is a randomly spawning cave that contains the legendary Pokemon Groudon. Terra Cave only appears after defeating the Elite Four.
its on route 115 but you have to have kyogre,groudon and rayquaza
First become Pokemon champion then go to the weather institute which is placed southwest of fortee city go to the top and talk to the scientist he tells you of a drought or a heavy downpour on a certain route depending on the weather condition you can find a secret cave on the route he mentions which leads to kyogre and groudon.
Route 111 (Desert)
If you've beat the elite four talk to weatherman. rainy day = kyogre, sunny day = groudon
in the terra cave near route 115

Go to the weather institute and talk to the scientist. He will say there is a drought on a particular route. Go to that route sharpish and look for a cave. Groudon will be in there.
Talk to the weatherman. He'll tell you something about some route and on it you'll find a diving spot you've never seen before. Talk to him again or before and he'll say the same thing for groudon. Hope this helps! :)
first you beat the elite 4 then go to meteor falls on route 114, go to steven and battle him, groudon will apear if you beat him

there is no route 16 in Pokemon emerald
There is no cave in Pokemon Soulsivler called Emerald cave. If you are talking about the Embedded Tower which is where Kyogre, Groudon and Rayquaza can be caught than that is on route 47 west of Cianwood city. If that's not what you are looking for than tell me and i will tell you but there is no Emerald cave.
Go to the weather institute on route 119 and go to the very top and you ll find him.
You can get groudon in Pokemon soulsilver and kygore in Pokemon heartgold (both are found in the embedded tower on route 47).
