Best Water Temperatures for Freshwater Fishing<\/span><\/p>\n

There are many factors to consider when trying to determine the best temperature for your target species.<\/span><\/p>\n

The steady temperature outside a fish\u2019s viable range, as well as sudden cold fronts and heat waves, will have a significant impact on a fish\u2019s movement and feeding patterns.<\/span><\/p>\n

Best Water Temperatures: Per Species<\/span><\/strong><\/p>\n

Largemouth Bass<\/span><\/strong><\/p>\n

Optimal Water Temperature: 65-75\u00b0F<\/span><\/p>\n

Breakdown: While largemouth bass have a relatively wide active temperature range for a primarily freshwater species (functioning well between 39-90\u00b0F), they do not feed continuously and are very picky about their prey.<\/span><\/p>\n

Favoring larger fish, they tend to feed when baitfish are most active within their waters, with a longer-than-normal period between their meals.<\/span><\/p>\n

Their optimal feeding temperature is the temperature that triggers their baitfish to school and forage near the surface.\u00a0<\/span><\/p>\n

While it\u2019s true that it\u2019s never really too cold for bass to bite, their feeding is going to slow down significantly as waters near the 40\u00b0F mark.<\/span><\/p>\n

Water Temperatures Acceptable for Fishing: 50-84\u00b0F<\/span><\/p>\n

Smallmouth Bass<\/span><\/strong><\/p>\n

Optimal Water Temperature: 63-68\u00b0F<\/span><\/p>\n

Breakdown: With a more precise feeding range than largemouth bass, the smallmouth bass is typically more active throughout the day and is keen on smaller bait like crayfish, insect nymphs, and small baitfish.<\/span><\/p>\n

This makes their feeding window feel more exact, as they will be keen to jump on anything that crosses their path when the temperature\u2019s right.<\/span><\/p>\n

Their faster metabolism also makes them more affected by ambient temperature, and though they can be caught near freezing, they are much less likely to bite outside of their acceptable range.<\/span><\/p>\n

Water Temperatures Acceptable for Fishing: 48-74\u00b0F<\/span><\/p>\n

Striped Bass (Freshwater)<\/span><\/strong><\/p>\n

Optimal Water Temperature: 50-70\u00b0F<\/span><\/p>\n

Breakdown: Stripers in freshwater are going to react more quickly to temperature changes than they will in saltwater or brackish waters.<\/span><\/p>\n

Stripers are also an anadromous cool-water species that migrate to freshwater to spawn, though many are locked in reservoirs.<\/span><\/p>\n

Spawning occurs at around 61-69\u00b0F, and striped bass will go through an anorexic phase when this happens, typically between April and June.<\/span><\/p>\n

Immediately following this, however, stripers will be at their peak activity and tend to be quick to bite regardless of temperature during this period.<\/span><\/p>\n

Around the year, freshwater stripers will ultimately have a wider optimal and acceptable range for fishing as their patterns are more predictable and food sources tend to be more contested.<\/span><\/p>\n

Water Temperatures Acceptable for Fishing: 46-80\u00b0F<\/span><\/p>\n

Musky & Pike<\/span><\/strong><\/p>\n

Optimal Water Temperature: 60-65\u00b0F<\/span><\/p>\n

Breakdown: Northern pike and muskie have a similar body morphology that makes them quite viable at a wide temperature range.<\/span><\/p>\n

There\u2019s a lot of conflicting data out there on optimal temperatures for catching both fish, which may have to do with their regional acclimation, as both are found in lakes, rivers, and reservoirs throughout the U.S.<\/span><\/p>\n

Averaging these numbers out gives us a narrow optimal water temperature. Though both fish retain a higher degree of activity even nearing freezing temperatures, these ambush predators become significantly selective below the 45\u00b0F mark.<\/span><\/p>\n

Water Temperatures Acceptable for Fishing: 45-80\u00b0F<\/span><\/p>\n

Catfish<\/span><\/strong><\/p>\n

Optimal Water Temperature: 68-72\u00b0F<\/span><\/p>\n

Breakdown: While channel catfish are the most abundant throughout the States, most catfish are affected by temperature similarly.<\/span><\/p>\n

They tend to become most active at roughly 70\u00b0F and scavenge any available smaller food source, making them quick to take most baits and rigs at this temperature.<\/span><\/p>\n

Catfish are truly one of the least particular varieties out there, so as long as conditions are right, you\u2019re sure to nab a few.<\/span><\/p>\n

As temperatures move below 50\u00b0F or above 80\u00b0F, catfish become increasingly sluggish and seek the shelter of deeper waters and drop-offs.<\/span><\/p>\n

Water Temperatures Acceptable for Fishing: 50-81\u00b0F<\/span><\/p>\n

Walleye<\/span><\/strong><\/p>\n

Optimal Water Temperature: 40-45\u00b0F<\/span><\/p>\n

Breakdown: Primarily found in the Midwest and central Canada, walleye favor colder temperatures and are at their most aggressive just before spawning.<\/span><\/p>\n

This typically occurs just as water temperatures begin to rise above freezing and reach into the low 40s, making mid-March and early April prime time for catching walleye.<\/span><\/p>\n

It\u2019s important to note that walleye spawn earlier in rivers and shallow bodies of water, given the more immediate effects of the temperature shift.<\/span><\/p>\n

Walleye are also very active in the fall, between August and October, following their optimal range.<\/span><\/p>\n

Water Temperatures Acceptable for Fishing: 32-75\u00b0F<\/span><\/p>\n

Crappie & Perch<\/span><\/strong><\/p>\n

Optimal Water Temperature: 45-72\u00b0F<\/span><\/p>\n

Breakdown: Crappie and perch are both going to become relatively inactive as water temperatures approach freezing, with perch being able to handle slightly colder waters.<\/span><\/p>\n

However, they\u2019re going to have to eat at some point, and with the right bait and technique, they can still be caught in near-freezing temperatures.<\/span><\/p>\n

Their optimal temperature is going to fall in the near 70\u00b0F range, with the best timing being their summer feeding frenzies.<\/span><\/p>\n

Water Temperatures Acceptable for Fishing: 33-80\u00b0F<\/span><\/p>\n

Trout<\/span><\/strong><\/p>\n

Optimal Water Temperature: 52-64\u00b0F<\/span><\/p>\n

Breakdown: Though slightly colder for cutthroats, bulls, and brook trout, and slightly warmer for brown trout, rainbow trout\u2019s optimal feeding range generally is within the mid-50s to low 60s, which gives a good all-around estimate for most species of trout.<\/span><\/p>\n

Trout will typically favor the slightly colder ends of their optimal range in shallower bodies of water than they will in deeper lakes and reservoirs, so it\u2019s important to know your target water body\u2019s depth.<\/span><\/p>\n

Water Temperatures Acceptable for Fishing: 40-70\u00b0F<\/span><\/p>\n

When is it Too Cold for Fishing?<\/span><\/strong><\/p>\n

Cold weather affects fish similarly to how it affects most animals, by slowing their metabolism and causing them to seek shelter and reduce activity, or migrate to find warmer waters.<\/span><\/p>\n

Many species of fish are going to react differently to the cold, some (like walleye) springing to life in near-freezing waters, while others will dive to the bottom of a lake or reservoir, or seek debris or cover.<\/span><\/p>\n

While many fish have an acceptable range for when they can be caught, some species will still bite as the temperature drops below that range.<\/span><\/p>\n

This will help you to understand your target species\u2019 response to sudden shifts in temperature.<\/span><\/p>\n

Overall, it\u2019s going to be too cold for fishing when the target fish either have moved on from your body of water to survive, or they\u2019re going to be reluctant to jump for bait even if it touches the bottom.<\/span><\/p>\n

When is it Too Hot for Fishing?<\/span><\/strong><\/p>\n

Similar to their reaction to cold fronts, sudden heat waves can cause fish to run from the shore or become listless and find cover in lakes or reservoirs.<\/span><\/p>\n

Because the bottom is better insulated and will remain at a lower temperature than surface waters on hot days, fish at greater depths remain active, though fish that rely on visibility to hunt may not bite as their focus shifts to self-preservation.<\/span><\/p>\n

On top of the temperature aspect of hot days, days with too much sun exposure can also cause fish to find ledges, holes, or other forms of shady cover to avoid getting burned.<\/span><\/p>\n

Many fish rely on low-light camouflage for feeding.<\/span><\/p>\n

A good rule of thumb is to simply avoid sunny, unusually hot days for most varieties of fish.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
