When tides are especially strong due to alignment of the sun and moon?

When tides are especially strong due to the alignment of the sun and moon, they are referred to as "spring tides." This phenomenon occurs during the full moon and new moon phases when the gravitational forces of the sun and moon align, resulting in higher high tides and lower low tides. The increased tidal range can lead to more pronounced coastal flooding and stronger currents. Conversely, during the first and third quarters of the moon, when the sun and moon are at right angles to each other, the tides are weaker, known as "neap tides."
