Rating: 🐟🐟🐟🐟 excellent day · 🐟🐟🐟 good day · 🐟🐟 average day · 🐟 poor day. ⭐ — a period coincides with sunrise or sunset.
Centred on the Moon’s upper transit — when it stands highest — and its lower transit, when it is directly underfoot.
Centred on moonrise and moonset. Shorter and weaker than the majors, but stronger when they coincide with sunrise or sunset.
Frequently asked questions
What are the best fishing days in May 2025?
By solunar theory the best days are 12–13, 26–27 May — around the full moon on 12 May and new moon on 27 May. 10–11, 14–15, 24–25, 28–29 are also good.
What time of day do fish bite best?
Solunar theory says fish feed most during the major periods — about two hours centred on the Moon’s overhead and underfoot transits — and less during the minor periods, about an hour around moonrise and moonset. A period that coincides with sunrise or sunset is said to be stronger (⭐ in the table).
Which days are poor for fishing in May 2025?
The weakest days by the theory are around the first and last quarter: 4–5, 20–21 May.
Which city are the times for?
The table shows Sofia by default; pick another city from the menu and the times are recomputed in that city’s local time. The day rating depends only on the moon phase, so it is the same everywhere.
Does the Moon really affect fishing?
John Alden Knight’s solunar theory (1926) is a popular fishing tradition, but research has not firmly confirmed it. The moonrise, moonset and transit times are computed astronomically to the minute; what they mean for fishing is tradition.
Moonrise, moonset and the transits are computed astronomically for the chosen city and match the US Naval Observatory to the minute. Solunar theory is a fishing tradition without firm scientific confirmation — the calendar is a guide, not a promise of a catch.
