Saltwater Fly Fishing Moon Phases



The link below displays the approximate Moon phases for any given month – both now and well into the future!  (This can be especially helpful when planning a saltwater trip.) For official phase times and dates for all seasons and any month, log on and enter the timeframe you are interested in (both the month and the year). Click here for the moon phases forecasting tool.

Spring Tides

When the moon is full or new, the gravitational pull of the moon and sun are combined. At these times, the high tides are very high and the low tides are very low. This is known as a spring high tide. Spring tides are especially strong tides (they do not have anything to do with the season Spring). They occur when the Earth, the Sun, and the Moon are in a line. The gravitational forces of the Moon and the Sun both contribute to the tides. Spring tides occur during the full moon and the new moon.

Neap Tides

During the moon's quarter phases the sun and moon work at right angles, causing the bulges to cancel each other. The result is a smaller difference between high and low tides and is known as a neap tide. Neap tides are especially weak tides. They occur when the gravitational forces of the Moon and the Sun are perpendicular to one another (with respect to the Earth). Neap tides occur during quarter moons.
