On January 11 at 3:00 AM, high tide reaches its first peak at 31.248 feet at high tide. The corresponding low tide of this same day hits at 10 am at around 3.517 feet. There is a dramatic difference between the two tides occurring twice a day. On that same day, the second round high tide is at a height of 29.588 at 5 pm, a lesser degree than the first tide — but the low tide is still incredibly different, at 5.09 feet at 11 pm. Then around the 16, the tides move towards the more neutral disparity that was seen earlier in the month. Only to once again increase in disparity later on in the month, this shows a pattern of an increase twice a month.
According to its location on the Eastern seaboard of the Atlantic Ocean, New London experiences a semi-diurnal tide. Further south than Alaska, which shows a lesser degree of tidal changes during the period of increased disparity between the high and low tides. Additionally, there is much less difference between the high and low tides. The high tide maxes out on the 10th of January at 1 pm when it reaches 3.418 feet. The lowest low tide comes the next day, on January 11th at 11 pm at -0.671 feet. The first week is relatively even, with high and low tides not changing dramatically. The second week is where the disparity between high and low tides turns to be more of a dramatic difference.
Key West in Florida also shows semi-diurnal tides, with less disparity seen in the Alaskan tide readings. Key West has its largest disparity in the second week of January, and then evens out for the rest of the month. The highest tide occurs on January 11 at 2 am 2.177 feet. The lowest actually comes the day before on January 10 at 8 am -0.67 feet.
Strangely, it resembles the Connecticut tide more than the Texan tide, which correlates with research stating that much of the Atlantic Seaboard sees semi-diurnal tides. The west coast of Florida shows more diurnal tides that would be more similar to Eagle Point Texas data.
This is a clear indication of a diurnal tide. There is one high and one low tide per day, which is contrasting to the other three geographical points. There are much less dramatic differences between the height of high and low tide. High tide never gets above 1 foot, with low tide only maxing out at a little over -1 foot. Thus, there is very little difference, which is typical with diurnal tide patterns. Texas is dominated with only small changes, with some periods showing very little changes between high and low tide
