Weather events in Mine a Mountain are the fastest way to raise the value of your crystals. When one is active, crystals you mine and crystals already sitting on the map can roll a matching mutation, which is a positive multiplier on their sale price. There are six events in total, and knowing what each one does tells you which ones are worth dropping everything to play.
Quick answer: The six weather events are Rain, Blizzard, Acid Rain, Thunder, Starfall and Aurora. Each grants a matching crystal mutation that increases sale value, with Starfall and Aurora giving the most valuable mutations. As of July 11th, 2026, all weather events are temporarily disabled due to a bug, so you cannot trigger them right now.
The six weather events and what they do
Every weather event applies its own mutation to crystals. A mutation is a multiplier stacked onto a crystal’s base price, so mining during an active event lets you build up money far quicker than mining during clear weather. All six are useful, but they are not equal.
| Weather event | Value tier |
|---|---|
| Rain | Standard |
| Blizzard | Standard |
| Acid Rain | Standard |
| Thunder | Standard |
| Starfall | Highest value mutation |
| Aurora | Highest value mutation |
If you have a choice, prioritize Starfall and Aurora. Their crystal mutations sell for the most, so a mining session under either of these events pays out significantly more than the same session under Rain, Blizzard, Acid Rain or Thunder.
Tip: Some event mutations are meant to mirror the bomb mutations exactly. Thunder is supposed to grant the same 1.7x sale price and 1.5 crystal garden luck multipliers as the Thunder Bomb, and Acid Rain is supposed to give the 1.6x crystal sale value and 1.5 plot luck multipliers of the Poison Bomb.
When weather events happen
Weather events normally occur twice a day, plus during Admin Abuse moments. There is no published in-game schedule, and the player base does not know the exact times a day’s events will fire. That makes catching one a matter of timing rather than planning.
There are two reliable ways to know an event is live:
- Stay online in the game until one starts. This is awkward because of the 20-minute inactivity kick, so you have to keep moving.
- Watch the game’s official Discord server, which is by far the easier method for catching an event as it begins.
Why weather events are disabled right now
As of July 11th, 2026, weather events are turned off. The developers disabled them because of a mismatch between the crystal mutations granted by bombs and the mutations granted by weather, which were supposed to be identical. Because Thunder and Acid Rain were not matching their Thunder Bomb and Poison Bomb counterparts, the whole system was paused. The admins have acknowledged the problem on the official Discord and are working on a fix, but no return time is confirmed.
There is a second, related bug from the same date. Using Poison Bombs on crystals you already own that carry the Wet mutation completely cancels out the Wet mutation instead of combining with it. Combining mutations is meant to raise a crystal’s value, so this defeats the purpose. This one is recent, and there is no confirmed fix timeline for it yet.
Note: Because the events are off, you will not be able to trigger any weather while the fix is in progress. The quickest way to know when they come back is to keep an eye on the official Discord rather than waiting in-game.
Once the mutation mismatch is patched and events return, the play stays the same. Jump in the moment an event fires, mine as much as you can while it lasts, and aim for Starfall or Aurora windows when you want the biggest payout per crystal.
