Season (game mechanic)

This article is about the game mechanic. For the division of dubbed episodes in the animated series, see season. For the Pokémon GO mechanic, see Season (GO).

Seasons (Japanese: 季節 season) are a mechanic from the fifth generation of the Pokémon games.

Seasons will not change in-game automatically; they will change only upon exiting a cave or building, or crossing between two outdoor maps at a transition that involves a loading zone (such as by moving between the various sections of Castelia City or Nimbasa City, or moving from Driftveil City to Driftveil Drawbridge). Unlike in the real world, where each season lasts for approximately three sequential months (in the astronomical model) or exactly three sequential months (in the meteorological model), the seasons in Unova will change each month, going through the full cycle of spring, summer, autumn, and winter three times per year.

Pokémon GO

Main article: Season (GO)

Seasons were introduced as a mechanic to Pokémon GO on December 1, 2020 as part of the GO Beyond update. Each season lasts for three months (starting and ending on the first day of a month), with the Northern and Southern Hemispheres experiencing opposite seasons, based on the real-world meteorological season for that hemisphere.

Trivia

• Because February is included among the months considered as summer in the games, summer is the shortest season on average. Whereas the other seasons each last a total of 92 days in a real-time year, summer lasts for a total of 89 days, or 90 days in case of a leap year. In the real world, this is true for astronomical summer in the southern hemisphere, as the Earth is near perihelion; astronomical summer lasts only approximately 89 days, while winter lasts closer to 94. The opposite is in effect for the Northern Hemisphere.
• When summer and winter start in the Northern Hemisphere of the real world, the same season is in effect in-game. This is not true for spring and autumn: it is spring in-game when autumn starts in real life and vice versa. The opposite is true for the Southern Hemisphere: real-world spring and autumn start in months with their respective in-game seasons, while summer and winter start in in-game winter and summer respectively.
• In the astronomical model of seasons (used in North America and parts of Europe), seasons start at solstices and equinoxes. In the game, seasons start at the start of the month, as is the case in the meteorological model of seasons (used by meteorologists and in countries such as Australia).
• Pokémon Black and White, the first games to introduce this feature, were released during autumn in Japan, and the in-game season was spring. The international releases were released during spring in the Northern Hemisphere, and the in-game season was autumn.
