There are four major weather events in Scale Slimy Fish: Aurora (increases spawn rate of mutated fish and spawns 5 weather fish), Rainy (increases server luck), Thunder (increases server luck and spawns 5 weather fish), and Meteor (increases server luck, increases spawn rate of mutated fish, and spawns 2 weather fish). Apart from these special weather conditions, two normal weather events don’t affect gameplay. See our full guide below for detailed information on each weather event of Scale Slimy Fish.
Scale Slimy Fish has a dynamic weather system that changes the weather conditions every few minutes. Certain weather conditions apply different buffs, including Luck Boost, increased mutation chances, and even spawning exclusive fish. This complete Scale Slimy Fish weather events guide will tell you everything you need to know about each Weather Event and how to make the best use of it. So, let’s get started.
What Are All The Weather Events in Scale Slimy Fish
There are six different weather events in Scale Slimy Fish. Four of these will directly affect the gameplay, while two only apply cosmetic changes to the weather box. The table below shows all the weather events and their effects, so you know exactly what to do when a certain weather event spawns:
| Mutation | Description | Duration |
|---|---|---|
| Sunny | No effect. | 12 minutes. |
| Night | Certain fish have a higher spawn chance. The exact fish are currently unknown. | 12 minutes. |
| Aurora | Increases the spawn rate of mutated fish by 2x. | 8 minutes. |
| Rainy | Increases server luck by 1.2x. | 7 minutes. |
| Thunder | Increases server luck by 1.5x. Also spawns 5 weather fish that you can catch and give to Thunder Siam. | 7 minutes. |
| Meteor | Increases server luck by 2x. Increases the spawn rate of mutated fish by 2x. Also spawns 2 weather fish that you can catch and give to Thunder Siam. | 6 minutes. |
Meteor weather is the best weather event in the game right now. It gives you extra luck, the chance to complete your mutation index, and the chance to catch the best weather fish (each weather fish from the Meteor weather will give you 1715 Starlights).

When it spawns, focus on fishing as much as possible to catch mutated fish, high-rarity fish, and the 2 weather fish. You can scale the fish once the event is over.
Scale Slimy Fish FAQs
To earn Starlights in Scale Slimy Fish, you need to give weather fish to the Thunder Siam NPC standing in the middle of the map. You can catch weather fish during Meteor (2 weather fish), Thunder (5 weather fish), and Aurora (5 weather fish) weather.
No, there’s no way for players to spawn weather events on their own. Weather events occur naturally and have a completely random spawn order.
You can see the current weather event in the bottom right corner of your screen. If you look towards the top of your screen, you can see the remaining time of the current weather event as well as the next weather event.
