Last night I had a wander round to the Harbour and saw the effect of the very low tide. The boats were very low in the water and the Navigation Beacon was getting some maintenance by the locals. I put on the Welly boots and had a wander the tide was so low and the beach at Rosielle was massive even bigger than usual with no one about pure bliss. It was a bitter wind and a grey day but I enjoyed see the huge effect that nature has I wonder how many even notice?
The moon is a major influence on the Earth’s tides, but the sun also generates considerable tidal forces. Solar tides are about half as large as lunar tides and are expressed as a variation of lunar tidal patterns, not as a separate set of tides. When the 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 tides and two sets of neap tides occur (Sumich, J.L., 1996).
