Primary tide type on the Maine coast?

Explanation:
The Maine coast is dominated by a semidiurnal tide: two high tides and two low tides occur roughly every tidal day. This pattern comes from the Moon and Sun’s gravitational pull interacting with the shape and depth of the Gulf of Maine, creating two bulges of water that rise and fall in sequence each day. The two highs and two lows are usually close in height, though coastal features and water depth can cause some differences between the highs or the lows. A diurnal pattern, with only one high and one low per day, isn’t typical here. A mixed semidiurnal pattern describes two highs and two lows with noticeably unequal heights, which can occur in some places, but the baseline expectation along Maine’s coast is the standard semidiurnal pattern with two highs and two lows daily.
