Sunny / Clear weather boost
Sunny / Clear weather boosts Grass, Fire, Ground types — +25% raid damage, a higher catch level, and more spawns. Here's exactly what to chase when the forecast shows sunny / clear.
- +25% damage: boosted-type fast and charged moves hit 25% harder in raids, gyms, and Rocket battles. Stack a Grass attacker into a sunny / clear window for noticeably faster clears.
- Higher catch level: the wild encounter floor rises from level 20 to level 25. A weather- boosted catch can roll up to ~10% more CP and needs less power-up to reach its cap.
- More spawns: boosted types appear more often nearby — the best time to shiny-hunt a Grass or Fire type.
- Hourly updates: in-game weather refreshes every hour from a real-world provider and can lag the actual sky. Trust the in-game icon.
Weather boost mechanics in-game
Weather is the single biggest IV-quality lever in the game that costs you nothing extra. The right weather turns trash spawns into raid-ready stats and gives your counters a free 1.2× damage multiplier. This page lists which weather boosts which type, what changes when boosted, and how to plan around it.
The seven weather conditions
Pokémon GO recognises seven weather states — Clear / Sunny, Cloudy, Rainy, Snow, Fog, Windy, Partly Cloudy. Each boosts 1-3 specific types. The mapping is fixed across all regions and time zones; only your real-world weather data drives it.
What changes when a mons is weather-boosted
Wild encounters: level 25-35 (vs 1-30 normally) and IV floor 4 / 4 / 4. Raid catches: CP range is bumped to the boosted tier. Eggs hatch at level 22 instead of 20 (small but compounding). In battle, your attacker deals 1.2× damage on STAB attacks of the boosted type AND is treated as +5 effective levels.
Tactical timing
Stack weather with your priorities: walk-to-hatch on Cloudy days for Rock/Fighting eggs, time raids for matching weather to boost your top counters, do Community Day in matching weather to maximise hundo-hunt yield. See current weather conditions in-game; pair with the raid counter tool to plan which day to attempt which boss, and the type chart for the underlying multiplier table.
FAQ
How does weather boost work in-game?
When in-game weather matches a mons type, three things happen: that type spawns more often, CP at capture is boosted (+5 levels equivalent), and IV floor jumps to 4 / 4 / 4. Boosted attacks deal 1.2× damage in battle. Cloudy boosts Fighting + Rock; Sunny boosts Fire + Grass + Ground; Rain boosts Water + Electric + Bug; Snow boosts Ice + Steel; Windy boosts Dragon + Flying + Psychic; Fog boosts Dark + Ghost; Partly Cloudy boosts Normal + Rock.
What CP and level do weather-boosted catches arrive at?
Boosted wild encounters spawn at levels 25-35 (vs 1-30 normally), and the IV floor lifts from 0 / 0 / 0 to 4 / 4 / 4. Higher level + higher floor means weather-boosted catches average roughly 90 % IV floor + are immediately raid-ready at level 30. Save Pinap Berries for these.
Does weather boost stack in raids?
Yes — for the attacker. If your attacker's primary type is boosted by current weather, you deal 1.2× damage and your attacker is treated as +5 levels (CP up ~10%, HP up ~5%). Stack a Fire attacker on a Sunny day against an Ice raid boss for 1.6 (SE) × 1.2 (boost) = 1.92× damage.
Are raid bosses also weather-boosted?
Yes — and it's a double-edged sword. A weather-boosted boss has higher CP at capture (potentially great IVs once caught) but hits harder in the fight. Plan around it: Cloudy + a Fighting boss means it hits your Psychic counters extra hard. The /raids page flags weather-boost status for current bosses.
Can weather change mid-trade or mid-raid?
Weather updates roughly hourly based on real-world conditions in your area. Mid-raid weather is locked at the moment you start the fight. For trade-time CP, only the moment of receipt matters — receive at noon on Cloudy and your trade arrives weather-boosted even if Sunny by the time you check.
