A quick guide to times & catching
Encounter chance is the chance of meeting that Pokémon under the listed conditions. More filled bars mean a harder catch. Tap the difficulty label for the Pokémon’s base catch value and what it means. Your chance per throw depends on remaining HP, status conditions and the ball you use.
Morning: 04:00–09:59 · Day: 10:00–19:59 · Night: 20:00–03:59, using the game’s clock. Evolution time windows are shown separately for each method.
Radio, swarm and night-fishing rates cover replacement slots. Headbutt rates apply to the listed tree type; common and rare trees depend on your Trainer ID. Safari candidates depend on the area, objects and their development. Contest weights are not percentages. Calendar events can replace a land encounter slot.
