Trout are cold-blooded fish that prefer to live & feed in colder H2O around 53°F which holds more dissolved oxygen but as H2O warms, oxygen begins to dissipate, and trout become less active and will move up & down in the water column or to a different location to find colder temperatures.
Trout temperature tolerances vary by species, but not by a lot with Rainbow and Brown being the hardiest they are the most stocked and the most taken on the First Day of Trout Season.
Introduction:
Understanding the intricacies of trout activity and water temperature can greatly improve the success of your fishing endeavors. One such intricacy is the correlation between water temperature and trout activity. In this article, we’ll take a look at the world of trout behavior, shedding light on the optimal water temperatures for these fascinating creatures. We will deep-dive into how temperature changes impact their feeding, spawning, and general activity levels. So, whether you’re a seasoned angler or a curious nature lover, you’re sure to find some valuable knowledge on the unique lifestyle of trout in varying water temperatures.
Understanding Trout Activity: Water Temperature
Many variables go into when Trout is the most active. The most obvious time is in warmer months when the temperatures are starting to climb then early in the morning when the air and water are cooler than the rest of the day. Then late in the day just before dark when the sun goes down for the same reason. When the sun comes up in much warmer temperatures look for signs of insects over a stream even in early spring when a few degrees can make all the difference.
Those slight rises in the warmth will stimulate life meaning smaller insects that are native to the water and the ecosystem. Once you see a few insects flying over the water nature starts to wake up the bugs then the birds then the fish will rise to those thermal layers of warmer water that are exposed to the sun. It doesn’t take long.
Fly-fishermen use the native fly to catch the native Trout that can live in the same waters for up to 20 years. Trout who swim the streams love to feed on insects aquatic life and flies.
In early spring try using insects more towards midday when the sun gets a few hours of solar rays on the water and in later spring when the morning hours are cool enough because the sun hasn’t had the chance to push the temperatures too high for the Trout’s liking.
Trout is kind of funny when the water’s temperature is involved and will eat and stay active as long as the environment is comfortable around them and a stream when the temperature breaks ever so slightly. A few degrees can act as an alarm clock waking up the whole ecosystem including the Trout.
I like These Rules of Thumb for catching Trout
- Rule of thumb: If the air temperature is uncomfortable below freezing or too hot, it will be uncomfortable for the trout as well, since they are cold-blooded and their body temperatures reflect the temperature of the water they swim in. Because Trout are cold-blooded then they like water temperatures of 34 to 67 degrees but will feed in the best temperatures between 44 and 64 degrees.
- Take the temperature of the water and you can physically see it.
- Since Trout don’t have eyelids and can’t dilate their pupils, they must seek shade in the extreme sun to avoid bright lights. So if you can, fish under cloud cover when water temperatures are cooler or look for shady areas where you can quietly walk into the water using waders or hip boots.
- If the water moves above 60 degrees move upstream or deeper into the water column into cooler water
Understanding the behavior of trout, particularly about water temperature, is fundamental to enhancing your fishing experiences. As water temperatures rise, trout become more active. However, this increase in temperature often corresponds with a decrease in dissolved oxygen, triggering changes in trout activity.
Water temperature plays a significant role in trout fishing. Since trout are cold-water species, certain water temperatures are more conducive to their feeding and breeding patterns than others. Finding the optimal water temperatures for trout and fly types can greatly enhance your fishing experience.
Fishing for trout is a favorite pastime for many anglers. The thrill of reeling in a trophy trout as the crisp morning air surrounds you is unparalleled. But it becomes even more rewarding when you understand how the water temperature impacts trout activity. The activity level of trout changes as the water temperature rises. Trout needs water with a high amount of dissolved oxygen to thrive. However, as the water temperature increases, the level of dissolved oxygen decreases, causing trout to become less active.
Degree by degree, as the water temperature rises, trout fishing will reduce their activities to conserve their energy. Fishing during periods of high temperature may result in low catch rates as the trout becomes less active. But, don’t despair! The key is understanding the relationship between trout, water temperature, and the resulting trout activities.
It’s also interesting to note that different trout species have different temperature preferences. Some species prefer cooler water temperatures, while others thrive in slightly warmer waters. Therefore, understanding the specific water temperature preferences of various trout species increases the chances of a spectacular fishing excursion.

The Brook trout
Unlike the brown trout, gravitates to distinct temperatures. Any minor deviation from their ideal water temperature might cause them to lay low, affecting your fishing plans. The brown trout, however, tend to adapt more easily, so the brown trout fishing doesn’t get disturbed as often.
Fishing in a river isn’t the same as fishing in a lake or a small pond. The river, with constantly changing currents and temperatures, inevitably causes variations in the trout’s behavior. So, whether you’re fishing for the brown trout, which is more temperature-resilient, or the brook trout that’s a tad temperature-sensitive, being aware of the water temp is a step in the right direction.
Tracking water temperatures makes a significant difference in fishing, especially for trout. Knowing when the water temperature rises or falls allows us to forecast the trout’s behavior – whether they’ll be more or less active. So keep an eye on that water temperature and happy fishing!
The Effect of Lake Trout Activity and Water Temperatures
Lake trout, like most other fish species, are remarkably sensitive to water temperature variances and their activities dramatically fluctuate in response. So, if you’re seeking to catch trout, the time and temperature of the water can make a substantial difference.
Trout are cold-water fish and prefer water temperatures that are ideal for their bodily functions. Water temperature can affect trout activities such as feeding, migration, and spawning.
Of all these activities, feeding is perhaps the most influenced by the water temperature. Lake trout tend to be more active and likely to pursue prey in cooler waters. Hence, a keen angler seeking to catch trout should check the water temperature before casting a line.
For the hobbyist or serious angler, it’s essential to recognize these particulars; not grasping the significance of water temperatures can spell the difference between a fruitful day of fishing or returning home empty-handed.
At certain temperatures, trout become inactive and are less likely to bite, making fishing a less productive activity. Every catch becomes a lesson, and every fishing trip, a way to understand the trout’s behavior better.
So, what is the optimal water temperature for trout? This question is not as straightforward to answer. Various factors like the time of the year, geographical location, and water type, all play integral parts in defining the ideal water temperature for trout. The most resourceful way to enhance your understanding is by checking and keeping a record of the water temperatures each time you fish. Over time, you’ll be able to see patterns and make connections between trout activity and water temperatures.
While each species of trout has slightly different temperature preferences, the optimal temperature range for lake trout typically sits between 50°F and 55°F. When water temperatures rise above this range, trout activity often declines.
Metabolism, digestion, and general functions are limited, and the trout become stressed. Conversely, if the water temperature falls below 50°F, trout will start to lose their vigor and decrease their feeding. Essentially, cold-water fish like trout thrive in temperatures around their optimum thermal preference.
As an angler, knowing how water temperature affects lake trout activity is an invaluable advantage. It’s an integral part of fishing. By checking the water temperature regularly, understanding seasonal patterns, choosing the right time to fish, and aligning these with the trout’s optimal water temperatures, you will dramatically increase your chances of success on your next fishing trip.

Here are some strategies for catching trout in different water temperatures:
-
Cold Water (Below 50°F or 10°C):
- Slow Retrieval: Trout in cold water are less active, so slow down your retrieve to match their pace.
- Deep Fishing: Look for deeper pools or slow-moving sections of the river where trout tend to gather to conserve energy.
- Use Small Baits: Trout metabolism slows in cold water, so opt for smaller bait and lures that mimic natural prey.
- Focus on Nymphs: Trout often feed on nymphs in colder water, so using nymph patterns can be highly effective.
-
Moderate Water (50-60°F or 10-15°C):
- Vary Retrieval Speed: Trout become more active in moderate temperatures, so experiment with different retrieval speeds.
- Target Structure: Trout may seek cover near structure like rocks or fallen trees, so focus your casts around these areas.
- Try Dry Flies: As insect activity increases, trout may start to feed on the surface, making dry fly fishing productive.
-
Warm Water (Above 60°F or 15°C):
- Fish Early or Late: In warmer water, trout are more active during cooler parts of the day, so fish early morning or late evening.
- Look for Oxygenated Water: Trout need well-oxygenated water to thrive in warmer temperatures, so target areas with riffles or inflows.
- Switch to Streamers: Streamer fishing can be effective in warm water, as trout may be more aggressive and willing to chase larger prey.
- Fish Deep Pools: During the heat of the day, trout may seek refuge in deeper, cooler pools, so focus your efforts there.
-
Extremely Warm Water (Above 70°F or 21°C):
- Practice Catch-and-Release: Trout become stressed in water above 70°F, so consider catch-and-release practices to protect the population.
- Fish High Elevation Streams: High elevation streams tend to be cooler even in warm weather, providing better trout habitat.
- Use Barbedless Hooks: Reduce harm to trout by using barbless hooks, which are easier to remove and cause less damage.
- Fish in the Evening: If fishing during the day, focus on early morning or late evening when water temperatures are cooler.
Always remember to check local regulations and guidelines for fishing, especially regarding catch limits and catch-and-release practices, to ensure the sustainability of trout populations.
