Best Answer: There are four tides during a revolution of the earth. A major and a minor high tide and a major and a minor low tide. Roughly, the time is about 6 hours but local coastal, weather and sea floor conditions will have an effect.herefore on the new moon and full moon days the high tides take place earlier than the mean interval. When the moon is at a quarter (90 degree), the high tides occur latter than the scheduled time. These phenomena are called priming and lagging of the tides.
