If you only care about the short answer, here it is. My testing in several fishing sessions shows that mythical fish in Fisch are easier to catch during Rain and Fog. In clear weather you can still pull mythicals, but in Rain and Fog I consistently saw 15–30% more high-rarity catches over long sessions with the same rod, line, and enchants.
The rest of this guide breaks down how I tested this, how weather really interacts with “luck”, and how you can stack weather, enchants, and timing to squeeze every bit of value from your fishing runs.
How Luck Actually Works In Fisch (The Real Story)
When you first start playing Fisch it feels like pure RNG. Some days you hook three legendaries in ten minutes. Other days you stare at common fish for an hour and start thinking your account is cursed.
What I’ve learned after grinding Fisch for months is this. The game uses layered RNG. Your rod, enchants, bait, location and weather don’t magically guarantee a mythical, but they shift the odds just enough that, over a long session, the difference becomes obvious.
Weather is one of those levers that newer players completely ignore. Veterans quietly swap spots and rods the moment the sky changes.
Let’s talk about why.
Does Weather Affect Rarity In Fisch? (Tested Sessions)
I wanted real numbers, not just “my friend said Rain is OP”. So I ran a simple but long test across three days:
- Same account, same Destiny Rod build
- Same fishing spot rotation
- 45-minute sessions for each weather type
- Logged every rare+ catch (Epic / Legendary / Mythical)
Here’s a simplified version of the data from one of those test rounds.
| Weather | Session Length | Total Catches | Epic+ | Legendary | Mythical |
|---|---|---|---|---|---|
| Clear | 45 minutes | 92 | 19 | 5 | 1 |
| Rain | 45 minutes | 95 | 27 | 8 | 3 |
| Fog | 45 minutes | 89 | 25 | 7 | 3 |
Is this a perfect lab experiment? Of course not. RNG can spike either way in short windows. But when you repeat sessions like this over several days, a pattern shows up.
What I consistently see:
- Rain increases the rate of Epic and Legendary drops and gives a small but important bump to Mythicals.
- Fog behaves very similar to Rain, sometimes slightly better for Mythicals in my logs.
- Clear weather is fine for farming bulk fish or completing quests, but if you’re hunting that one big mythical, it’s the worst time to sweat for it.
The key takeaway. Weather doesn’t turn Fisch into a mythical-printing machine, but if you’re grinding high-value fish, treating Rain and Fog as “event windows” is one of the easiest upgrades to your strategy.
Why Rain And Fog Feel “Luckier” For Mythicals
So what’s going on under the hood? Fisch’s developers haven’t released full drop tables, but there are a few patterns I’ve noticed across my runs and from watching other high-level players stream their sessions.
Weather seems to modify rarity weights, not just bite rate. In clear conditions you get more commons and uncommons. In Rain and Fog, the commons drop slightly while the odds for Epic+ climb.
Certain mythical species appear almost tied to bad weather. A few mythicals in my logbook show up disproportionately during Fog sessions. When I tried to target them in clear skies with the same setup, the catches slowed to a crawl.
Weather synergies with enchants and location. Luck-focused Destiny Rod builds feel much stronger when the sky isn’t clear. It’s like stacking small buffs that add up.
None of this proves exact percentages, but from a player’s perspective the rule is simple. If the weather turns rainy or foggy and you’re not busy, you fish. Using totem locations or the weather machine can help you control conditions for optimal fishing.
Practical Weather Strategy For Higher Rarity
Let’s turn this into something you can actually use during a normal play session.
1. Treat Rain and Fog as limited-time events
When the sky changes, drop whatever low-priority task you’re doing. Swap to your best Destiny Rod setup and head to your strongest mythical spot. Think of it as an unscheduled mini-event.
2. Use clear weather for setup and utility
During clear conditions I usually:
- Craft or upgrade gear
- Experiment with new locations
- Farm quests and lower-rarity collections
That way, when Rain or Fog hits, I’m not running around unprepared.
3. Track a few sessions yourself
You don’t need a giant spreadsheet. Just note down:
- Weather type
- Session length
- Legendary and Mythical catches
After three or four sessions you’ll see why serious players swear by bad weather runs.
Weather vs Other Luck Factors: What Matters Most?
Weather is important, but it’s not the only thing shifting your odds. Here’s how it stacks up against other key factors based on my experience.
| Factor | Impact On Rarity (My View) | Notes |
|---|---|---|
| Rod type/build | Very high | Destiny Rod with right enchants is the baseline. |
| Enchants & line | Very high | Luck and rarity-focused enchants matter a lot. |
| Weather (Rain/Fog) | High | Noticeable boost over long sessions. |
| Location/biome | High | Some mythicals are basically location-locked. |
| Time invested | Medium | RNG evens out over long grinds. |
| Player skill | Low–medium | Mostly about not wasting bites and moving smartly. |
You’ll get the best results when you don’t rely only on weather. Instead, use weather as the multiplier on top of a strong rod, smart enchants, and good spot knowledge.
How To Maximize Weather Luck In 5 Simple Steps
Here’s a repeatable system I use whenever I log into Fisch.
| Step | Action | Why It Works |
|---|---|---|
| 1 | Check the sky before you do anything else | If it’s already raining or foggy, skip your normal warm-up. Equip your main Destiny Rod build and move straight to your best high-rarity location. |
| 2 | Lock in your “weather build” | Use a setup that leans harder into rarity and luck when the weather is favorable. You can swap to a speed or utility build when conditions go back to clear. |
| 3 | Commit to full sessions | Don’t judge weather impact off ten casts. Aim for 30–45 minute blocks where you stay focused in one or two locations so your sample isn’t completely random. |
| 4 | Rotate smart, not random | If Rain or Fog lasts a while, rotate between two or three known mythical spots rather than teleporting constantly. This keeps your travel time low and casts high. |
| 5 | Review your own data once a week | Take one minute to glance at your notes. If you see Fog producing your best mythicals, start giving Fog sessions priority over everything else. |
Expert Tips From Long-Term Testing
Here are a few things I had to learn the hard way.
| Tip | What To Do | Why It Matters |
|---|---|---|
| Don’t chase every rumor | Just because someone on Discord claims “Storm equals guaranteed mythical” doesn’t make it true. Test with your own build first. | Avoid wasted time on unverified strategies |
| Avoid splitting your attention | If you’re farming mythicals, don’t open ten other tabs, half-watch YouTube, and then blame “bad luck”. Missed bites add up. | Focus maximizes catch efficiency |
| Use bad weather for targeted hunts | When a specific mythical keeps dodging you, plan two or three Rain/Fog sessions focused only on that fish’s biome. | Strategic planning beats random grinding |
| Know when to stop | If you had an insane Rain session and then things go dry, take a break. Chasing a “hot streak” can burn hours with nothing to show. | Prevents burnout and wasted sessions |
| Respect clear weather, just differently | Clear skies are great for experimenting with new spots or leveling alts. You don’t have to log off; you just change goals. | Every weather condition has value |
FAQ: Weather, Luck And Mythicals In Fisch
Does weather actually increase mythical chances in Fisch?
Is Rain better than Fog for rare fish?
Can I still catch mythicals in clear weather?
How long do I need to fish to feel a weather difference?
Do I need a specific rod for weather luck to work?
Does bait change how weather works?
If you start treating weather as a core part of your luck strategy instead of just a visual effect, your rare and mythical catch log in the bestiary will look very different a week from now. Track a few sessions, adjust your builds around Rain and Fog, and you’ll see why experienced Fisch players quietly love bad weather.
