When Do Bass Spawn

Knowing when bass spawn is like having a secret fishing calendar, giving you an edge to reel in the big one. Bass spawning, a critical period of reproduction, is when bass are at their most vulnerable and predictable. This time is marked by the fish moving to shallower waters to lay their eggs. As an angler, understanding the timing can be the difference between a legendary fly fishing tale and just another day on the water.

This article aims to shed light on the elusive question, “When do bass spawn?” and equip you with knowledge about the spawning season. We’ll look at factors influencing bass spawning, how they impact your fishing approach, and why hitting the water at just the right time can lead to thrilling bass fishing experiences. Whether you’re a seasoned pro or just starting, this guide is your insider tip to mastering the art of bass fishing during spawning season.

Bass Spawning Season

Bass spawning season varies across the country and is typically influenced by water temperature. In the spring, as the waters warm up, bass shift into their reproductive phase. The timing isn’t marked by the calendar but by the temperature of the water.

In the southern states, such as Florida and Texas, bass can begin spawning as early as late February because the water warms up sooner. You might find largemouth bass spawning by February, while spotted bass aren’t far behind, starting around March. As for smallmouth bass, they tend to wait until the waters are just right, around late April.

Bass in states like Minnesota and other northern regions may not start spawning until June. Optimal water temperatures for spawning typically range between 60 and 70 degrees Fahrenheit. Even the phases of the moon, especially the full moon, can influence their spawning activity, coaxing them into the shallows for their springtime rituals.

In California, bass might be found spawning between March and June, but expect some variations. Weather conditions, unseasonable temperatures, and climate change can cause some unexpected shifts in the spawning calendar.

Here’s a quick look at approximate spawning months, keeping in mind that these can vary:

Geographical Location

In southern states, bass can get a head start on spawning as early as February. But up north in Minnesota, they’re likely to wait until late May or June. It’s not just the states, either. Even within a single state, you might find bass in the southern parts spawning before their northern lake neighbors.

Not all water bodies are the same. In lakes, for example, bass often look for cozy coves or protected areas where the wear and tear of waves won’t disturb their nests. However, in ponds, it’s all about that sun-warmed shallow water.

Bass Spawning Water Temperature

When spawning, bass prefer their water to be neither too hot nor too cold. For largemouth bass, the magic number for the water thermometer is between 60-75°F. On the other hand, the smallmouth bass like it a bit cooler, spawning in water temperatures at 55-65°F. Spotted bass also prefer waters that are 55-70°F.

Why is this so important? Those temperatures are not just preferable—they’re optimal. Once the water starts to warm up in their habitat, bass metabolism kicks into gear and their spawning instincts take over. So keep an eye on the water temperature if you’re aiming to catch them during the spawn—or give them privacy during this important time. Remember, catching them outside of this temperature range might be a bit harder, as they’re not in their comfort zone.

Moon Phase

Bass tend to spawn with a noticeable uptick during the full moon and the new moon. Here’s why:

  • Full Moon: This increased illumination not only makes your nighttime fishing trip more scenic, but it also encourages bass to spawn. The gravitational pull is stronger, too, making the fish more active.
  • New Moon: On the flip side, during the new moon, the sky is darker, but the gravitational effects are still strong. It provides bass with a sense of security so they can spawn in large numbers.

During the quarter moons, the pull is less dramatic and the lights are dimmed, leading to a bit of a lull in spawning activity. Remember, while the moon’s phases are a guide, Mother Nature has the final say. So, keep an eye on the sky and check those temperature charts.

Water Depth

Water depth plays a crucial role in where and how bass spawn. Largemouth bass aren’t too picky, typically choosing spots that range from 1-8 feet deep. That’s just shallow enough to get some sunlight and cozy enough for their eggs. On the other hand, smallmouth bass go a bit deeper, searching for that sweet spot between 2-15 feet. Spotted bass set up their spawning grounds even deeper, typically between 5-20 feet.

Bass behavior during spawning is also influenced by water clarity. In murky waters, they often choose shallower areas for spawning, a detail worth noting as you navigate these conditions.

Additionally, the finicky nature of bass extends to their response to water temperature and level. These adaptable fish will alter their preferred depth based on the temperature of the water and its fluctuating levels. Observing these nuances can enhance your understanding of bass behavior during spawning.

How to Catch Spawning Bass

As spring’s warmth beckons bass to create new life, their behavior grows more predictable. Pre-spawn finds eager bass prowling the shallows, aggressive, and searching for prime nesting sites. When bedding time arrives, they diligently guard their future with fierce strikes at perceived threats. Post-spawn brings retreating bass, now focused on recovery and evasion in sanctuary waters. By matching your approach and bait presentation to each phase—probing staging areas, tempting guardians, or rousing the weary—your chances of enticing a strike dramatically improve.


Pre-spawn is the kickoff to one of the most exhilarating times for bass fishing. This phase occurs as water temperatures rise and is typically marked by aggressive bass behavior.

During pre-spawn, bass migrate from their winter haunts towards the shallows. They’re hungry, active, and on the prowl for a place to bed. This makes them more susceptible to your lures. But timing is everything, as this stage transpires when water temperatures are in the lower 50s.

How do you capitalize on this period? Try these techniques:

  • Staging areas: Bass favor areas like points, channels, and depressions near spawning flats. These act as rest stops on their migration path.
  • Baits: You’ll want to mimic their prey. Fast-moving options like crankbaits and spinnerbaits do wonders and can provoke that instinctual bite from bass that just can’t resist the chase.
  • Colors: Match the hatch with natural shades or go bold with brights, tailored to the water’s clarity and color.

Remember, it’s a game of cat and mouse, so vary your retrieve speeds. A slower pull in cooler water temperatures and a zestier zip as degrees tick upwards.


Curious about when bass set the stage for the future? Spawn is that critical time. It typically unfolds from early spring to summer, though it hinges on water temperature rather than calendar dates. Once the water warms, bass scout the shallows for the perfect spot to lay and fertilize their eggs.

Here are some tips for successful angling:

  • Locate the beds: Don polarized sunglasses and slowly patrol the shallows. You’re looking for those distinctive nests.
  • Sight fishing: With crystal-clear vision, you can spot bass guarding their turf. A drone or binoculars can give you that eagle-eye advantage.
  • Choose the right bait: Soft plastic baits are your best friends. Think worms, lizards, and craws that mimic natural threats.
  • Finesse is key: A gentle presentation can trick that vigilant bass into thinking it’s just another day in the neighborhood.

Remember, they’re not just fish; they’re soon-to-be bass parents. Give them respect while you angle. That way, everyone wins—you get the thrill, and the bass get to keep spawning.


Post-spawn is like the after-party for bass, except it’s less about celebration and more about recovery. This period typically kicks in after bass spawn in the spring, when water temperatures reach about 60 degrees Fahrenheit.

During the post-spawn, bass, especially females, are often weary. They’ve exhausted significant energy and their metabolism is focused on recuperation. You might notice they seem less aggressive and more fickle in their feeding habits.

Catching bass in the post-spawn is all about finesse and understanding bass behavior. Think about where you would hang out if you were tired but hungry. The bass are likely transitioning to deeper areas, moving slowly from the shallows towards their summer haunts. Here’s how you can up your chances:

  • Where to cast: Cast transition areas like points, ledges, and drop-offs near spawning flats in slightly deeper water than normal.
  • What to use: Slowly work natural-colored jigs, swimbaits that mimic baitfish, and even subtly-presented topwater lures over post-spawn bass
  • How to retrieve: Employ a slow, steady retrieve, letting the bass dictate the pace, and observe their activity levels to determine bait presentation.

Remember, in post-spawn, it’s all about making it easy for the bass to say yes to your lure. Minimal effort, maximum reward.

Bass Spawn FAQs

Will Bass Bite During Spawn?

Yes, bass will bite during spawn when feeling protective, though less so out of hunger. Focused more on safeguarding eggs than eating, aggressive males will strike perceived threats to their nests. Skillfully provoking defensive reflexes by mimicking predators can entice fierce bites. Monitor conditions like temperature, clarity, and pressure that dictate aggression levels. With a subtle, natural approach, the spawn’s guardians turn catchable.

What Is the Best Bait for Bass Spawn?

The best lures for tempting spawn-guarding bass are natural-looking soft plastics like subtly presented finesse worms or creatures rigged weedless, matching the hatch with live bait where permitted, or splashing subtle topwaters to draw reflex strikes from protective fish. The wacky worm’s fluttering fall and the Ned rig’s bunker imitation are excellent choices. With an adaptable approach, observant anglers can convince the bass to bite, even when they are not truly feeding.

What Triggers Bass to Spawn?

Warming water temperatures, primarily between 60-70°F, coupled with lengthening daylight trigger bass endocrine systems to begin spawning, much like coffee arouses our metabolism. This thermal and photoperiod combination indicates to bass that conditions are favorable for reproduction. While not primary factors, supplemental influences like optimal clarity, depth, and ample food sources help ensure a successful spawn. So when water warms to bass’ liking and sufficient light signals it is spring, the spawning commences.
