Solunar periods: how the moon shapes fishing every single day
There's a common mix-up between "Haml & Fasad" and "solunar" — both are about the moon, but they answer completely different questions. Haml & Fasad tells you "is this whole month strong or weak?" Solunar tells you "today specifically, what time is best?"
The idea, simply
Solunar theory holds that the moon's pull affects things not just when it's directly overhead, but also when it's exactly underfoot on the opposite side of the planet. Both moments are called "Major periods" — each lasting around two hours, happening twice a day.
Major and minor periods
- Major period: the moment the moon passes directly overhead or underfoot — the two strongest periods of the day, lasting around two hours each.
- Minor period: falls between the two majors, shorter and lighter in effect, but still noticeable.
Solunar with the tide, or instead of it?
On a coast with a real tide (the Gulf, Oman, Morocco), the tide-based ebb/flood rule stays the strongest signal, and solunar is an extra layer — if a solunar period lands inside a good tide window, the opportunity gets even stronger. On a weak-tide coast (Mediterranean, Red Sea), solunar becomes one of the most important signals available at all, which is why it feeds directly into the "golden window" calculation there.
Where to find it in the tool
Every solunar period for the day appears in the "best times" list below, labeled "Solunar" and sorted by time alongside the tide windows. If you find a solunar period and an ebb/flood window close together on the same day, that's usually your strongest window.
