Three types of weather conditions affect the catch and spawn rates of fish and axolotls:

Rainy Weather
Nuclear Weather
No Weather (includes clear skies or any weather that isn’t rainy or inside a nuke zone)

Rainy Weather Conditions

Counts as Rainy Weather when any of the following are happening:

It’s misty and rainy
It’s raining
It’s heavy rain with low visibility
A Thunderstorm Weather Station is active within the area you’re fishing
A Snow Weather Station is active within the area you’re fishing
A Snow Aurora Weather Station is active within the area you’re fishing

Nuke Weather Conditions

Counts as Nuke Weather when any of the following are happening:

There’s a radiation storm
There’s a Nuke Zone
A Mothman Weather Station is active within the area you're fishing
A Radstorm Weather Station is active within the area you’re fishing
A Nuke Zone Weather Station is active within the area you’re fishing
A Skyline Valley Weather Station is active within the area you’re fishing

Your CAMP’s active weather machine takes priority and overrides all other weather conditions, including Nuke Zones and Natural Weather — only one weather effect applies to the spawn rates at a time. You’ll also receive the full benefit from someone else’s CAMP weather if you’re fishing there, even if you don’t own the weather machine yourself.

Spawn Rates

When you cast your line, the game checks for the rarest fish first—like Local Legends or Axolotls. But those only have a chance to appear if you’re in the right spot, during the right month, or standing at a marked Local Legend location.

If those checks fail or don’t apply, it moves on to look for Glowing or uncommon fish, depending on the bait and weather.

If none of those roll successfully, the game falls back to regular fish from the region or even junk items. This fallback system guarantees that every cast gives you something, even if it’s not the fish you were hoping for.

Note from Duchess:

Rainy Weather and Improved Bait are all you need to catch nearly every fish — especially once you start upgrading your fishing rod with hook and reel mods.
