Various weather conditions happen in the Inner City, changing the ambience as providing gameplay modifiers that can help or harm survivors.
Weather conditions are divided into 2 types. Only 1 of each condition type may be present at the same time:
Weather: Provides buffs/debuffs that may affect survivors or zombies, such as movement speed reduction or knockback resistance/vulnerability. May have different effects indoors.
Weather changes every 27-30 minutes. There is a small chance for a Weather condition to not appear at all (i.e. "calm weather").
Time of Day: Represented by a change in sunlight/moonlight. Affects the spawn rate of zombies and chance of hordes.
Time of Day rotates every 45-60 minutes, equivalent to 2 Weather change intervals. Time of Day follows the cycle of Morning -> Afternoon -> Evening -> Night.
Each of these conditions uses a sets of background music, which are played alternately. Furthermore, each set of music will differ in intensity, depending on current Aggro.
Low temperature and high moisture may lead to large amounts of vapor condensing near the ground, obscuring the vision of survivors and zombies alike. It's this blinding effect that has earned fog the title of "#1 Most Hated Weather Effect", according to surveys done by the Fairview CB Association.
Effect:
Decreases infected sight range by -25%.
Cover minimap in a layer of fog.
Indoors: No effect.
Frenzy
Frenzy
The Red Fog from the SEZ seeps, driving zombies to a frenzy and strengthening their abilities. No quarter will be given, and no savior will come.
Effect:
Increases infected sight range by +25%.
Increases infected hearing range by +25%.
Increases Horde rates by +25%.
Decreases knockback effects on infected by -25%.
Heatwaves
Heatwaves
Bouts of extreme heat and sunlight have various negative effects on living beings, such as heat cramps, heat rashs, and worst of all, heat syncope. Survivors are advised to wear head covering alongside light, breathable clothings, seek shades whenever possible, and rehydrate often.
Effect:
Increases hunger levels for survivors by -25%.
Rain
Rain
A light drizzle is the perfect chance to laze around in your room or share an umbrella with your crush, but survivors rarely get the chance to do so. Regardless, rain is usually seen as a positive thing: It gives survivor clean water for drinking and planting, and the sound of raindrops can confuse zombies, mask the sound of gunfire, and make sneaking around much easier.
Effect:
Decreases infected hearing range by -25%.
Indoors: Decreases infected hearing range by -15%.
Thunderstorm
Thunderstorm
Great rain comes with great thunder, which conveniently serves as an excellent zombie distractor. Thus, thunderstorms are unusually sacred in the minds of Fairview residents - a common children's story depicts Zeus as a benevolent god, who will help good people by smiting zombies from above with his lightning spears.
Effect:
Decreases infected hearing range by -30%.
Indoors: Decreases infected hearing range by -20%.
Snow
Snow
Fairview is infamous for its snowsqualls, which may hit the city at any moment and cripples movement of humans and vehicles that are not normally equipped with winter gears. When facing this, consider building a snowman, start a campfire, or just enjoy the snow magic fantasy indoors.
Effect:
Decreases movement speed of survivors by -10%.
Indoors: No effect.
Wind
Wind
Zombies have a poor sense of balance due to their decaying vestibular system, making them prone to moving erratically, falling over or getting blown away in strong winds. It's debatable if this is a good thing however, as many veterans have attested to almost losing their lives from such an unpredictable shift in zombie movement.
Effect:
Increases knockback effects on infected by +25%.
Infected have swaying movement due to gusts of wind.
