Major vs minor solunar periods: how anglers use bite windows

Solunar charts mark major and minor periods tied to moon and sun positions. Learn the difference and how FishCast computes bite windows on your phone — even offline.

Key takeaways

• Major solunar periods are typically longer peak windows; minor periods are shorter secondary windows.
• Solunar is a timing aid, not a guarantee fish will bite.
• Combine solunar windows with pressure, wind, and tide when relevant.
• FishCast computes solunar times on device and caches them for offline trips.

What major and minor mean

In solunar theory, major periods are the primary activity windows and minor periods are shorter secondary windows based on moon and sun positions. Anglers use them to prioritize effort.

How to use bite windows without superstition

• Note today’s major and minor times before you leave.
• Be on productive water a little early.
• Still read conditions — pressure and wind can override a “perfect” window.

FishCast’s offline edge

FishCast keeps solunar computing on device so you are not stuck when the canyon kills your signal.

FAQ

What is the difference between major and minor solunar periods?

Major periods are generally the longer primary windows; minor periods are shorter secondary windows in the solunar day.

Do solunar charts guarantee a bite?

No. They are timing guidelines. Weather, pressure, tide, and fish behavior still decide the day.

Can I see solunar times without cell service?

Yes. FishCast is built to cache and compute key fishing times on your device.
