When the sun<span>, </span>moon<span>, and </span>Earth<span> are in </span>alignment<span> (at the time of the new or full</span>moon<span>), the solar </span>tide<span> has an additive effect on the lunar </span>tide, creating extra-high hightides<span>, and very low, low </span>tides<span> — both commonly called </span>spring tides<span>.</span>
