- Higher CP.
- Fewer Power Ups required.

- Less Candy needed to reach higher levels.
Weather-boosted Pokémon provide a great head start if you’re planning to power up your Mewtwo.

Weather boosting also changes the CP range of the Mewtwo encounter.
| Encounter | CP Range |
|---|---|
| Normal Raid | 3377–3492 CP |
| Weather Boosted | 4222–4366 CP |
A weather-boosted hundo will have 4366 CP.
Is It Worth Waiting for a Weather Boost?
If you’re looking for the strongest possible Mewtwo, then yes.
Weather-boosted encounters save a significant amount of Stardust because the Pokémon starts at a higher level.
However, if your priority is simply collecting Mega Energy or hunting for a Shiny, it’s still worth raiding regardless of the weather.
Can Mega Mewtwo X Be Shiny When Weather Boosted?

Weather has no effect on whether your Mewtwo encounter is Shiny.
