How do the tides work?

The gravitational pull of the Moon and the Sun both affect the Earth’s tides. When Sun, Moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides — both commonly called spring tides.

One week later, when the sun and moon are at right angles to each other, the solar tide partially cancels out the lunar tide and produces moderate tides known as neap tides. During each lunar month, two sets of spring and two sets of neap tides occur.

Weather, wind and tides are very important to all of us who live near the coast. Use the weather and tide links on the right to find out more and keep track of what’s happening in our area right now.
