Timing the Tides

We all know that moon influences the timing of tides in the ocean. In 24 hours we get 2 High Tides and 2 Low Tides but the timing keeps on changing.

Here is a very simple method to calculate the same. All you need to know is what is the phase of the moon for the day? On Poornima (Full Moon Day) and on Amavasya (No Moon Day), the High Tide is at 12 noon and 12 midnight and the Low Tide is at 6 am and 6 pm. Every day the tide is delayed by 45 mins over previous day. This means one day after Poornima/ Amavasya, we have the High Tides at 12.45 AM and 12.45 PM and the Low Tides at 6.45 AM and 6. 45 PM.

Test Question for Paanchvi Pass: What is the timing of the High Tide seven days after Amvasya? 5.15 AM and PM
So what has all this got to do with “Escape from Mumbai”? It is important to know the timing of High Tide and Low Tide while visiting some of the coastal locations like Kulaba Fort and Usranicha Pagar.
