Spring tides (the bigger ones) occur every full moon and new moon. Neap tides (weaker ones) occur every 1st and 3rd quarter moons. There is approximately 28 days in one lunar â¦cycle, which consists of one of all mentioned moon phases - therefore, spring tides occur every 2 weeks, and neap tides occur every 2 weeks.
