Weather Boost Pokémon GO is one of the most important mechanics in the game, directly affecting spawns, IVs, and battle performance in ways many players overlook.
If you’ve ever opened Pokémon GO and noticed the in-game weather matches what’s happening outside, that’s not just for show. Weather actually affects how the game plays, and that’s where Weather Boost comes in.
Weather Boost can make Pokémon stronger, increase CP, and even affect which Pokémon appear. It’s one of those mechanics that quietly influences your gameplay without you always realising it.
So let’s break down what Weather Boost is, how it works, and why it matters more than you might think.
What Is Weather Boost Pokémon GO?
Weather Boost is a system that enhances certain Pokémon types based on real-world weather conditions.
When specific weather is active in-game, Pokémon of matching types:
- Appear more frequently
- Are caught at a higher level
- Have higher CP when caught
- Gain boosted damage for their moves
In short, the weather can make Pokémon stronger and easier to build.
How Weather Boost Pokémon GO Works
Pokémon GO uses real-world weather data and translates it into in-game conditions such as:
- Sunny
- Rainy
- Cloudy
- Windy
- Snowy
- Foggy
Each weather type boosts specific Pokémon types. When the weather icon appears in the top-right of your screen, that’s your clue that certain Pokémon are currently boosted.
What Weather Boost Does in Pokémon GO
Weather Boost impacts several parts of the game at once:
Higher CP Pokémon
Weather-boosted Pokémon are caught at a higher level, which usually means higher CP. This makes them immediately more useful without needing as many power-ups.
Stronger Attacks
Moves that match the boosted weather deal extra damage, which is especially noticeable in raids and gym battles.
Increased Spawn Rates
Pokémon that match the active weather appear more often, making it easier to hunt specific types.
Better Stardust Efficiency
Because boosted Pokémon start stronger, you’ll often spend less Stardust powering them up.
Weather Boost Pokémon GO Spawn Changes Explained
Here’s a simplified breakdown:
- Sunny / Clear → Grass, Fire, Ground
- Rainy → Water, Electric, Bug
- Partly Cloudy → Normal, Rock
- Cloudy → Fairy, Fighting, Poison
- Windy → Dragon, Flying, Psychic
- Snow → Ice, Steel
- Fog → Dark, Ghost
This is why some Pokémon seem to appear “out of nowhere” during certain weather conditions.
Weather Boost Pokémon GO IV and CP Bonuses
Weather Boost is especially helpful if you:
- Want higher CP catches
- Are building raid teams
- Are low on Stardust
- Are hunting specific Pokémon types
- Want better raid performance
Catching weather-boosted Pokémon is one of the easiest ways to build stronger teams without heavy investment.
Does Weather Boost Affect IVs?
No, and this is an important point.
Weather Boost does not improve IVs. It only affects the Pokémon’s level and CP when caught. You can still catch a weather-boosted Pokémon with poor IVs, just as you can catch a non-boosted Pokémon with excellent IVs.
Higher CP does not always mean better long-term potential.

Is Weather Boost Important for Raids?
Yes, very much so.
In raids:
- Weather-boosted Pokémon deal more damage
- Certain raid counters perform much better
- Raids can feel easier during favourable weather
This is why experienced players often plan raids around weather conditions when possible.
Are There Downsides to Weather Boost?
There are a couple of things to keep in mind:
- Boosted Pokémon may be harder to catch
- Weather can change unexpectedly
- The boosted types may not be what you need
- Bad weather in real life can make playing unsafe
Pokémon GO will also disable Weather Boost if conditions are considered dangerous, prioritising safety.
Common Weather Boost Mistakes Players Make
- Assuming boosted Pokémon have better IVs
- Powering up everything just because it’s boosted
- Ignoring type advantages
- Forgetting weather affects raid damage
- Not checking the weather icon at all
Weather Boost is powerful, but only if you use it intentionally.
