là do lực hút của mặt trời và mặt trăng, ví dụ: khi phần nước biển ở gần mặt trăng, mặt trăng sẽ hút nước biển lên, tương tự mặt trời, vì mặt trời ở xa nên lực hút sẽ yếu hơn khi ở gần. Khi trái đất, mặt trời và mặt trăng xếp thành góc vuông thì lực hút sẽ được dải đều ra nên không gây thủy triều     ~HT~
