Starting later this week, 50 more Pokémon will be added to Pokémon GO. In addition, the game is going to have new weather features added. Players might see certain Pokémon more often based on what the real-world weather is.
The new Pokémon include Treeko, Torchic, Mudkip, and others that were originally discovered in the Hoenn region in the Pokémon Ruby and Pokémon Sapphire video games. Those three Pokémon will be the first to appear, and more from the Hoenn region will be added over the next several weeks.
The Pokémon GO map in-game will be updated with weather effects. This includes new visuals that change based on the weather where you are. For example, if it is raining outside where you are, the in-game map will show a dark, cloudy, sky and rain falling down.
Soon, the weather in the real-world where you are playing Pokémon GO will have an effect on the Pokémon that you see in Pokémon GO. Players odds of discovering Mudkip will greatly improve on rainy days. That’s just one example. Some other Pokémon will be more commonly found during various weather conditions. The real-world weather will also cause some Pokémon’s attacks to be more effective than usual.
