Trout Fishing In The Rain – Is It Better?

When I’m guiding, I can’t just pack up and go home when it starts to rain, I have to stay and make the best of it for my clients, and this has taught me that trout fishing in the rain can be a great time to fish. Trout fishing in the rain can be like someone ringing the dinner bell for trout and they can almost instantly go on the feed when it rains.

Trout fishing in the rain can be uncomfortable and difficult but the trout will often feed more during the rain. For anglers that know how to fish for trout in the rain, it can be the best time to catch the biggest trout and even the most trout. Trout fishing in the rain requires some new tactics.

It’s important to understand why trout fishing in the rain can be so good and why trout often feed more when it rains. Knowing this will help you pick the right tactic and the right baits for more fish.

Do Trout Bite In The Rain?

The answer is yes, my funny answer that I tell my clients is that the trout are already wet, so why do they care if it’s raining. There are reasons why trout will actually feed more in the rain than at other times.

I was guiding five anglers one day and I had my buddy come out and help. We had five anglers out for 7 hours and almost no trout were hooked. It was a bright sunny calm day and the trout were totally off.

After the guided trip was over, my buddy and I went up the river about 10 km and fished for about an hour in one of my favorite spots. With two very skilled trout anglers in a pool full of fish, you would think we would catch some but after an hour we only landed one 8 inch trout. The fishing just sucked!

Then a short rain shower started with some thunder in the distance and within minutes we started hooking trout as fast as we could get our flies in the water.

The same flies that the trout were ignoring the whole time were now hot and within an hour we had landed 23 trout with a couple over 20 inches. The fishing went from horrible to fantastic as soon as the rains started. But Why? I have experienced this many times and there is few reasons that I will discuss below.

Let me just say now, that with the thunder that day, we should have actually stopped fishing and took cover, and I would highly recommend you never fish in thunderstorms.

Why Is Trout Fishing In The Rain Good?

Trout fishing in the rain can be great for big rainbow trout that will feed heavily on all the food being washed into the river.

There are 5 reasons why trout fishing in the rain can be very good.

  1. Raindrops can knock insects out of the air and into the water. The rain can also knock the insects off the vegetation, off the leaves and grasses along the riverbank, and into the river. This influx of food can trigger a feeding frenzy.
  2. The rain washes in nutrients and small particles, small insects, and all kinds of debris that the small baitfish will start to feed on. This triggers a chain reaction, since the baitfish are feeding and losing some of their cautiousness to feed on all the new food, the bigger predator trout will start to get active and start feeding on the baitfish and anything else that they can eat.
  3. The water becomes less clear and that allows the trout to become less cautious and feed more which makes it easier to catch them. Big trout may move out from their hiding spots around log jams and into the open.
  4. Low light is one of the best times to fish for trout, and when it rains it often becomes darker and this can get the trout feeding.
  5. Another possible reason that trout fishing in the rain is better is that the trout may feed more with less pressure on them since most anglers will head for their vehicles before or when the rain starts.

Knowing how to fish for the trout in the rain is important and some baits and tactics will work better than others.

Best Tactics For Trout Fishing In The Rain

If it’s a light rain most trout fishing tactics will probably still work but as the rain gets heavier and the river clarity starts to drop some tactics might work better than others.

Fly Fishing In Rain

Trout fishing in the rain can be good

My buddies and I try our best to hit the river on rainy days and just after the rain simply because we know that the big trout come out to hunt under these conditions.

When it’s raining and the rain knocks in a lot of insects fly anglers can start catching a lot of trout. The rain will wash in beetles, ants, mayflies, moths, and a whole lot of other insects, and that means that almost any fly could work.

When there is a huge variety of bugs in the water, I like to nymph fish and I like to go with bigger and often brighter flies. The rain will often sink flies on the surface so fishing below the surface is often best.

When nymphing in the rain, I like attractor patterns that will stand out amongst all that food and debris being washed down the river.

Prince nymphs, rainbow warriors, bead head nymphs, and leggy nymphs are all good choices for trout fishing in the rain.

The woolly bugger fly is a great fly for fishing in the rain because it is big and it stands out. Even bright woolly buggers in white and yellow can be hot in the rain.

Fishing Flies With Spinning Rods

Even if you don’t fly fish, you can still take advantage of flies and you can fish flies with spinning reels. I drift flies below a float or use my advanced bottom bouncing methods which can be extremely effective when fishing for trout.

Dry Fly Fishing Can Be Good In The Rain

It can be tough to dry fly fish in the rain because the small flies will get pushed under by the rain drops, but big bulky dry flies patterns like grasshoppers, crickets, and beetles patterns can be a great choice.

Streamer Fishing In The Rain

This big brown trout was caught on a 4-inch streamer pattern and it was the 3rd one of this size in 20 minutes. Most anglers are lucky to even catch 1 a year like this from this river.

Big trout feed on baitfish and big trout can feed more in the rain and after the rain so using streamers can be very effective. I love throwing big streamers in rain for big trout like the one in the picture.

Some of my favorite streamer flies are woolly buggers, bunny leeches, zoo cougars, zonkers, and muddler minnows.

I have caught big trout on streamers from one inch to 6 inches so it’s a good idea to have an assortment in your box.

Bigger streamer flies like the Articulated Monkey Fly, or the Granato’s Sasquatch Fly, the CF Chuck-N-Duck Fly, and the CF Whistler are all good choices.

Spin Fishing For Trout In The Rain

Spin fishing can be excellent at any time but when it rains anglers can spin fish for trout using lures or by drifting baits under a float, or by bottom bouncing their flies and baits.

If it’s done right, bottom bouncing can be very effective, especially in pocket water or shallow rivers that are not great for float fishing or for lure fishing. If you aren’t sure what bottom bouncing is, check out my page Bottom Bouncing – 5 Proven Guide Tips For More Fish

Float fishing is an excellent way to present baits in bigger deeper rivers. You could drift flies under a float and you can also use worms, spawn bags, and beads.

One of my best baits when fishing for trout in the rain and after the rain is the pink worm from Berkley and the Mad river worms. The red worm color has been one of my most productive colors when the river starts to get murky.

Lure Fishing For Trout In The Rain

Fishing Dirty Water

An angler fishing for trout in dirty water. This river is usually gin clear but it just finished raining and my clients were faced with dirty water conditions. A quick switch to bigger brighter flies kept them on the trout.

It sometimes doesn’t take long for some rivers to start getting dirty especially if it’s a hard downpour. If the water clarity get to bad you may need to pack it up and go home, but, there are some things that you could try to up your chances.

I use lures that are bright colored and make a lot of noise like the Blue Fox Vibrax spinner or a crankbait with a rattle. Lures like a spoon just won’t do so well in dirty water. The noisy lures will get the trout’s attention and the can home-in on the lure with just their lateral line.

Bigger lures are also a good choice since it gives them a bigger target and bigger lures make more noise.

If I am bait fishing, I will use larger and brighter baits like big spawn bags or even big flies like a chartreuse woolly bugger. If you only have small spawn bags on you just thread two or three of them on the hook at the same time.

Bait fishing can also be a good choice because it’s slow moving and allows the fish to find the bait.

Guide Tip: When the water is really muddy the trout will still feed but the problem is that the trout can’t see your bait so you literally have to bump them in the face with it.

I will often seek out smaller clear water creeks that enter the main river and I will fish where they enter. These creeks will often stay clear or will clear up faster and the water just below where the creek enters will often hold some fish and be clear enough to catch them. You could also try fishing up into the clear creeks.

Gear Up For The Rain

If you are wearing waders you won’t need to worry about your legs getting wet. However if you don’t have a rain jacket or wading jacket to keep your upper body from getting wet, you can’t prevent the rain from dribbling down your body and into your waders.

I’ll often have a lightweight packable rain jacket in my vest during the summer and I will use my wading jacket in the spring, fall, and winter.

I use the Frogg Toggs Xtreme Lite Jacket as my packable jacket for summer fishing. It’s not the most durable or the best rain jacket but it’s a great emergency rain jacket that has saved my butt on many occasions. You can check the Frogg Toggs Jacket out at Bass Pro Shops.
