A:The baseline for giving how high or low the tides are is called the MLLW, or Mean Lower Low Water. This is the average low water height for a complete 19-year Metonic Cycle (also known as the National Tidal Datum Epoch) – basically the time it takes for a high-tide to occur at exactly the same time and date. This number is what is used on nautica...
A:Sometimes you might notice in our tide charts that the high/low for a given date is not there. The reason for this is the fact the tides don’t quite fit into a daily cycle, and actually average 24 hours and 54 minutes between complete cycles. So those ‘missing’ cells are where the tide time has jumped into the next day.
A:Similar to the answer above, there are instances where 2 high tides occur in one 12-hour period. If that is the case, the second time will be in the second time column (PM) but will say AM so you know it is in same period as the first time of the day. These are rare, depending on the layout of the harbor and surrounding geographically features.
A:The truth is we don’t predict King Tides in our tide charts. ‘King Tides’ refer to the highest tide of the year. There are many factors that can increase the height of the tide the are not caused by the predictable phases of the moon, which our tide charts are based on. Things like flooding and river surges can change the height of the tide on an...
A: Many mariners use a general rule that says that slack water (no movement of water in any direction) occurs at high tide and low tide. However there are exceptions depending on the location and its currents. There are other factors that affect the appearance of slack water: 1. Wind driven currents can alter the timing of slack water. 2. Changes i...
A:There are several really great organizations with scientifically accurate information on tides: 1. NOAA’s Educational Resources on Tides 2. NOAA’s Tides & Currents Site 3. The National Oceanography Centre (UK) We also have several interesting and helpful articles on Tides: 1. Amazing Facts About the Tide 2. Tides 101: The View from Space 3. Myth-...
Learn how tides are caused by the moon and sun, and how they affect the water level and currents on the coast. Find monthly tide charts for your location and tips for boating, fishing, and enjoying the shore.
The moment the sea reaches its maximum level on a certain coastal location is referred to as high tide, while the moment it reaches its minimum level is referred to as low tide. Tides are categorized into three varieties based on the frequency and symmetry of their wavelength.
