During the last 400 years, there have been 39 instances or 'Extreme Proxigean Spring Tides' where the tide-producing severity has been near the theoretical maximum. The last one of these was on March 7 1995 at 22:00 hours Greenwich Time during a lunar Full Moon. There were, in fact cases of extreme tidal flooding recorded during these particular spring tides which occur once every 31 years.
An usually high tide of 20 to 30 percent is expected from today until 23rd July and residents living along the coasts are advised to take precaution.Those with houses on stilts over the sea are being advised to move out for the duration of the highest tide.The high tide coupled with strong wind and high waves would be dangerous for those living close to the shoreline.
Kota Kinabalu and other areas nearby should expect strong wind and high waves pounding its shoreline.
Today, 40 years ago men set foot on the moon.Launched on July 16, 1969, it carried Mission Commander Neil Alden Armstrong ,Command Module Pilot Michael Collins , and Lunar Module Pilot Edwin Eugene Aldrin Jr.
On July 20, Armstrong and Aldrin became the first humans to land on the Moon, while Collins orbited above .
Tides are caused by the gravitational interaction between the Earth and the Moon. Tides are the cyclic rising and falling of Earth's ocean surface caused by the tidal forces of the Moon and the Sun acting on the Earth .The relative distance of the Moon from the Earth also affects tide heights. When the Moon is at perigee the range is increased and when it is at apogee the range is reduced.
