99 Nights in the Forest Biome Refresher: Start Time & Countdown

Updated August 19, 2026 By AllThingsHow Staff 1.8M playing now

The Biome Refresher is the next scheduled update for 99 Nights in the Forest, and it hasn’t started yet: the developer’s schedule sets it to open on August 22 and run for a full week. Rather than adding a headline gimmick, this one is a maintenance-and-balance pass aimed at the game’s weaker regions, with the goal of bringing every biome up to a more even standard of things to find and do. about 680,000 of players have already marked themselves as interested.

It arrives in one of Roblox’s busiest survival games. 99 Nights in the Forest, from Grandma’s Favourite Games, is holding around about 1,800,000 players in-game right now and has been favorited over nine million times, so a broad balance update lands in front of a very large audience. The exact start and end are on the card below.

What the Biome Refresher covers

This is a content and balance update rather than a new-map or holiday event. In the developer’s own listing it’s described as “some love for the biomes” — the plan is to strengthen the areas that currently feel thin and make sure the range of content and items is more consistent from one region to the next. In practice that means:

  • Improvements to the weaker biomes, so the parts of the map players tend to skip become worth exploring.
  • A more even spread of items and content across every biome, closing the gap between the richest regions and the emptiest ones.
  • A steadier overall experience, since no single area should be far ahead of or behind the rest after the pass.

There’s no limited-time collectible attached to it in the listing, so the value here is a better map to survive in rather than a reward to rush for.

When it runs and how to plan around it

The window runs from August 22 at 1:00 PM ET to August 29 at 2:00 PM ET — a full week. Because that’s an Eastern time, players elsewhere should shift it accordingly: the opening lands in the late evening across the UK and Europe, and in the small hours of August 23 through much of Asia and Australia. With seven days on the board there’s no need to be online at the exact opening; the changes are structural, so they’ll be in place for the whole run and beyond.

How it fits the game’s update rhythm

Grandma’s Favourite Games has kept 99 Nights in the Forest on a steady update cadence through the summer, with drops running anywhere from about a week to two weeks apart. The Biome Refresher picks up about a week after Kids have Jobs closed on August 15, which itself followed The Bee MINI Biome, The Dino Kid Update and The Aliens Revenge across a busy summer of updates. The pattern is telling: after a stretch of themed additions, this refresher reads as a consolidation beat — a pause to even out everything the earlier events layered on before the next themed drop. As of August 22 it’s the update on the calendar.
