Weather is a dynamically shifting gameplay mechanic within each match of Battle Royale. Weather is split two types:
Weather Events are localised and randomised events which can happen multiple times a match, but only in one location at a time. Currently there are only two weather events, these being Tornados and Lightning Storms.
Visual Weather is a type of weather in which the only change is the aesthetic of the map, with restrictions to visibility. These will occur across the entire map at once, and will either appear during specific in game events, or periodically in normal matches.
Tornadoes take twenty-five seconds to form and will last roughly eight minutes. Tornadoes will suck up and throw props around the environment, similar to how they can be moved with a Grab-itron or Saucer, and will pull nearby players into it and upwards, allowing for Glider Redeploy. Tornadoes are localized and will slowly move across the map.
Lightning Storms take eight seconds to form and will last roughly three minutes. Webs of lightnings will occasionally appear on the ground shortly before a lightning strikes from the stormy clouds. Players will take 10 damage if they are struck by a lightning, but gain a movement speed boost when hit. It can strike 2-3 players at once. Players are more likely to get struck by a lighting when on a high area or when swimming. Lightning Storms will also create fire.
Fog was first seen in Chapter 2: Season 8, as a periodic weather change which affected the whole island at once. Fog makes visibility difficult, but does not change any gameplay mechanics. It will dissipate after a short time.
Blizzards have only appeared during the 2019 iteration of Winterfest. They functioned very similar to fog, appearing across the entire island at once and dissipating after a short time.
Permanent Fogs have appeared several times in different Fortnite events. Fortnitemares 2020, for example, had a thick purple Fog across the entire island for the entirety of the event, but only during night time.
- Update v6.00: The entire Island is covered in a mist during Season 6 and made it slightly more difficult to see.
- Update v6.20: The mist got thicker and turned into a fog for the start of Fortnitemares, making it significantly harder to see.
- Post-Butterfly Event: Fog has dissipated.
- Ice Storm: Fog returns for the period of the event.
- Update v11.30 (Winterfest 2019): Introduced Blizzards. They will appear at random and get more intense as the days pass, they'll apply to the entire island at once. They will also dissipate at random.
- End of Winterfest: Removed Blizzards.
- Fortnitemares 2020: Midas' Revenge: Fog returns with a dark purple color. It only appears at night.
- Update v18.00: Fog returns, with it being dynamic and randomly appearing and dissipating throughout the match.
- Update v19.00: Fog slightly altered, changing its color from white to more blue.
- Content Update v19.01 #2: Tornadoes and Lightning Storms are introduced, after being teased in the season trailer.
- 13th January 2022: Changes to weather:
- The maximum amount of vehicles that can be present in a tornado has been increased from 1 to 2.
- The maximum amount of physics objects in a tornado have been increased from 50 to 75.
- 14th January 2022: Changes to weather:
- Tornado chance increased from 80% to 100%, meaning each game will have at least one tornado.
- Tornadoes can now spawn in first 6 storms circles, previously 5.
- Delays between a new Tornado reduced from 3 minutes to 2 minutes.
- Delays between a new Lightning storm reduced from 3 minutes to 2 minutes.
- 17th January 2022: Tornadoes spawn less frequently.
- 13th January 2022: Changes to weather:
- Update v20.00: Removed Tornadoes and Lightning Storms.
- Update v21.00: Re-added Tornadoes. Tornados are now marked on the map with a small icon.
- Some locations such as Misty Meadows had visible mist in the area. This was not as thick as a fog, but noticeable as the mist was localised to that area only.
- Tornadoes were likely removed in Chapter 3: Season 2 due to the IO Airships across the map. If a Tornado were to interact with these floating landmarks, they would likely cause issues as many parts of the structure would ignore the Tornado.
