![]() ![]() At 0553 the tide will have dropped to 1.5 meters and you can not traverse after this time until the tide comes back up to 1.5 meters on its next rise. Olías-Alvarez detected for the first time semi-diurnal tides in the DNP, in a piezometer at 6 km from the sea, with an amplitude of only 1 cm, much smaller than the amplitude measured by Fernández-Ayuso and Rodríguez-Rodríguez in the PSOL and PDUL, of 2. Bring it across to the falling tide curve and then down to the time. Now, bring a line down from the 1.5 meter requirement to the sloped line on the left. First enter the high tide time and each hour after that. Since you noticed a new moon a few days ago and the range of tide from low to high matches a spring tide, use the spring tide sinusoidal shape curve. The range of tide is 0.6 low and 4.5 high. So the times for transit in the morning are anywhere from midnight until a time whereby the ebbing (dropping) tide is 1.5 meters (this will be before 7:45) and some time after 7:45 where the flooding (rising) tide returns back to 1.5 meters.įirst look at the ebbing tide curve. The depth of the water at this time would only be 1.6 meters. A diurnal tide features one high and one low tide per lunar day while. Semi-diurnal tides feature two high tides and two low tides each lunar day, and are the most common type of tide, when the transition from low to high lasts approximately 12 hours and 25 minutes. Since low tide is 0.6 meters this is lower than the requirement. There are three different types of tides: semi-diurnal, diurnal, and mixed. ![]() The times then, should be adjusted as such: The answer lies in when will the tide be 1.5 meters and above?ĭaylight savings is in effect and the chart above says add 1 hour to the times to get DST. So this means the tide needs to be 1.5 meters or higher. Please try to solve the answer yourself first before cruising the answer. According to your requirements of 1 meter clearance below the keel, what times in the morning is it safe to traverse the shallow area? ![]()
