Master Pokemon Go Weather Week with advanced strategies, optimal spawn locations, and Castform evolution tactics
Weather Week Event Overview
Prepare for an immersive weather-themed adventure during Pokemon Go’s Weather Week event, where atmospheric conditions directly influence your Pokemon encounters and rewards.
This comprehensive guide covers all Weather Week essentials including precise timing, weather-based spawn mechanics, raid strategies, and Collection Challenge tactics.
Niantic officially announced the Weather Week details on March 6, confirming a mid-March event focused on atmospheric Pokemon mechanics and transformations.
The event showcases Generation III’s Castform as the featured Pokemon, with its unique ability to change forms based on current weather conditions. Special weather-influenced spawns, exclusive Field Research tasks, and updated raid bosses create a dynamic gameplay experience.
Here’s your strategic overview to maximize rewards and complete all event challenges efficiently.
The Pokemon Go Weather Week event activates from March 14, 2024 at 10:00 AM local time through March 18, 2024 at 8:00 PM local time, providing four full days of weather-themed gameplay.
Advanced Spawn Strategies by Weather Condition
Castform naturally takes center stage as the event’s headline Pokemon. This metamorphic creature will spawn more frequently throughout the event, with its elemental type adapting to match current in-game weather patterns.
Weather conditions significantly influence spawn diversity during Weather Week. Each atmospheric state triggers different Pokemon appearances, encouraging players to explore various locations and times.
Beyond weather-dependent spawns, several Pokemon will appear more commonly in the wild regardless of atmospheric conditions, providing consistent hunting opportunities.
Dedicated trainers have increased chances to encounter these special Pokemon variants during their explorations.

Pro Tip: Monitor weather forecasts in your area and plan hunting sessions around predicted weather changes to maximize Castform form diversity. Sunny/Clear weather typically occurs midday, while Rainy weather often appears during actual precipitation periods.
Event Bonuses and Optimization
Weather Week delivers substantial bonuses designed to accelerate your Pokemon Go progress and resource accumulation.
Advanced Strategy: Combine Weather Boost catches with the 2× Stardust bonus for quadruple Stardust efficiency. Use Star Pieces during intensive catching sessions to further multiply your Stardust gains by 1.5×, creating optimal resource farming conditions.
Common Mistake to Avoid: Don’t waste Premium Battle Passes on non-event raids during Weather Week. Focus on event-exclusive raids that feature weather-themed Pokemon with potential shiny variants.
Field Research Rewards Strategy
Weather Week introduces exclusive Field Research tasks with valuable encounter rewards. Completing these research assignments (regardless of current weather) may yield these special Pokemon encounters.
Additionally, Pokemon Go participants might encounter the elusive Snowy Form Castform through Field Research completion.
Research Optimization: Visit high-density PokeStop areas to maximize task acquisition. Delete less rewarding tasks to refresh your research queue efficiently. Snowy Castform typically requires specific weather conditions or special tasks—focus on completing all available research during snowfall weather for best results.

Raid Strategy: Focus on tier-specific counters—use Rock, Electric, and Grass types against Flying/Water bosses. Coordinate with local raid groups to maximize Premier Ball rewards through team contribution bonuses. Remember that weather-boosted raid bosses have higher CP but provide better reward potential.
Showcases and Collection Challenges
Special PokeStop Showcases will feature event-appropriate Pokemon eligible for competition throughout Weather Week.
Additionally, Niantic will implement Collection Challenges specifically for Weather Week. Successful completion of these challenges rewards participants with Stardust and Incense items.
Showcase Tactics: Submit your largest or most rare weather-themed Pokemon to maximize showcase points. Collection Challenges typically require catching specific Pokemon—prioritize these during your hunting sessions to complete multiple challenges efficiently. Save Incense rewards for Community Days or future events with boosted spawn rates.
