Welcome to Your Solunar Fishing Forecast & Calendar
Fishing isn't just about skill — it's about timing. Many anglers believe the Moon plays a role in fish feeding patterns and movement, and a Solunar Fishing Calendar can help you anticipate the windows when fish are more likely to be active, giving you an edge on the water.
At MoonPhase.Today, we combine traditional solunar theory with real-time lunar data — moon phase, illumination, and age — so you can plan trips around the feeding windows most relevant to your favorite species.
Why Solunar Theory Started on the Water
Solunar theory was developed by outdoorsman John Alden Knight, who spent years through the 1930s studying fish and game behavior in relation to the sun and moon. Knight examined dozens of potential factors affecting animal activity before narrowing his focus to the sun, moon, and tides, coining the term "solunar" to describe their combined effect. He published the first Solunar Tables in 1936, introducing the major and minor period system that still forms the basis of solunar calendars used by anglers today.
It isn't a guarantee — water temperature, barometric pressure, and seasonal patterns generally have a bigger impact on the bite — but it's a useful factor to stack alongside the conditions you already watch.
Major vs. Minor Solunar Periods
The Solunar Fishing Calendar above is built around four daily windows. Knowing what triggers each one helps you decide when to be on the water.
| Period | Triggered By | Typical Length | What To Expect |
|---|---|---|---|
| Major | Moon directly overhead or directly underfoot (lunar transit) | ~1.5–2 hours, twice daily | The peak moments in the solunar forecast when fish are most actively hunting for food |
| Minor | Moonrise and moonset | ~30–60 minutes, twice daily | Secondary activity periods that can still provide excellent catch opportunities |
How Moon Phase Shapes the Bite
At the new and full moon, moonrise and moonset fall close to sunrise and sunset, so a Minor solunar period often lines up with dawn or dusk — already a prime low-light feeding window for many species. That overlap, more than the phase itself, is likely why these two phases get so much attention from anglers. Here's how many plan around the cycle:
| Moon Phase | Illumination | Common Angler Notes | Best Strategy |
|---|---|---|---|
| New Moon | 0% | Moonrise and moonset fall close to sunrise and sunset, so a Minor period often lands right at dawn or dusk | Fish the dawn and dusk Minor periods, and darker water can favor low-light presentations |
| First Quarter | ~50%, waxing | Transitional activity as the cycle builds | Watch for a Major period stacking with morning or evening light |
| Full Moon | 100% | Moonrise near sunset and moonset near sunrise again put a Minor period at dawn or dusk | Try the dawn and dusk Minor periods, or a night session where allowed under bright skies |
| Last Quarter | ~50%, waning | Activity trending back toward daylight hours | Reliable all-around window for a standard day trip |
Why Solunar Periods Matter
Major Feeding Times
The peak moments in the solunar forecast when fish are most actively hunting for food, usually when the moon is overhead or underfoot.
Minor Feeding Times
Secondary activity periods, typically during moonrise and moonset, that can still provide excellent catch opportunities.
Seasonal Patterns
How specific species respond to the lunar cycle can shift across spawning, summer, and cold-water seasons.
Cross-Check Conditions
Barometric pressure, water temperature, and clarity can outweigh a solunar peak — always weigh them together.
Plan Your Trips with the Solunar Fishing Calendar
Our downloadable Solunar Fishing Calendar highlights notable days for each month, including New Moon and Full Moon periods. With this information, you can plan trips around the days and windows that many anglers watch most closely — helping you decide where to fish, what bait to try, and when to cast your line.
Solunar Notes for Common Catches
Largemouth Bass
Some anglers target Major periods around dawn and dusk, especially during the spring spawn.
Trout
Feeding often tracks closely with water temperature and insect activity, with Minor periods used as a secondary cue.
Catfish
Many catfish anglers favor overnight sessions around the full moon, when nocturnal feeding tends to pick up.
Saltwater & Inshore
Redfish, snook, and similar species are often planned around tide movement first, with solunar periods layered on top.
Cast With Confidence
Pair the Solunar Fishing Calendar above with your local weather, water temperature, and tide data before heading out. A stable barometer and moving water often matter just as much as the moon phase itself.
Solunar Fishing Calendar FAQ
What is a solunar fishing calendar?
A solunar fishing calendar is a daily schedule of Major and Minor activity periods calculated from the sun and moon's position for a given location. Anglers use it alongside weather and water conditions to plan when to be on the water.
What's the difference between major and minor solunar periods for fishing?
Major periods happen when the moon is directly overhead or underfoot and last roughly 1.5 to 2 hours — they're considered the strongest windows. Minor periods happen at moonrise and moonset, last about 30 to 60 minutes, and offer a shorter secondary opportunity.
Does the moon phase really affect fish behavior?
Some anglers and researchers report a link between moon phase and feeding activity in certain species, but results vary by fish, water body, and season. Water temperature and barometric pressure are generally considered stronger factors.
What is the best moon phase for fishing?
There's no single best phase for every trip, but many anglers favor the new and full moon, since moonrise and moonset fall close to sunrise and sunset during those phases — lining a Minor solunar period up with the low-light dawn or dusk bite many species already favor.
How accurate is solunar theory for fishing?
Solunar theory is based on decades of angler observation rather than controlled scientific proof. It works best as one input alongside water temperature, pressure, clarity, and season, rather than as a stand-alone predictor.

Do Moon Phases Affect Insect Activity - Quick answer Yes — moon phases measurably affect nocturnal insect activity, primarily through illumination. Flight activity, mating swarms, and biting pressure all increase around the full moon, while dark new moon nights shift the behavioral strategies insects use to navigate. The effect is real but uneven: nocturnal species respond clearly, while daytime insects are largely […]
