About Port Chatham tides
Port Chatham is a NOAA subordinate station (9455428): NOAA predicts its times and heights from Seldovia, Kachemak Bay (9455500) with offsets for this spot, so treat them as a close guide rather than an exact prediction. Heights are in feet above MLLW (Mean Lower Low Water), the datum of US nautical charts, so they line up with charted depths.
In the next 30 days, Port Chatham has two highs and two lows on 26 days and three turns on 4 days, and the daily range runs from 3.2 to 21.6 ft. That is a mixed tide: two highs and two lows on most days, of clearly different heights.
Use the curve above to time a harbor entrance, a beach walk, fishing a moving tide or clearing a shallow bar, and remember that wind, air pressure and river flow can push the real water level above or below the prediction. The daily tidal range in the tables shows how much water moves each day: bigger ranges around the new and full moon mean stronger currents.
The latest water temperature near Port Chatham is about 47°F, from NOAA station 9455500, 16 mi away, at 9:30 PM AKDT. Water temperature shapes where fish hold and feed, and tells you what to wear in the water, so check it alongside the tide before you head out.
Frequently asked
What time is high tide in Port Chatham today?+

What time is low tide in Port Chatham today?+
Today, low tide at Port Chatham is at 11:12 AM (4.4 ft), 11:57 PM (-0.7 ft).
What tidal datum do these Port Chatham tide heights use?+
All heights are given in feet relative to MLLW (Mean Lower Low Water), the standard NOAA chart datum for US tidal waters. A tide of 0.0 ft equals the chart datum; negative tides fall below it.
How accurate are these tide predictions?+
Port Chatham is a NOAA subordinate station (9455428). NOAA predicts its times and heights from Seldovia, Kachemak Bay (9455500) with offsets for this spot, so treat them as a close guide rather than an exact prediction. Real water levels can also differ with wind, air pressure and river flow.
What is the water temperature at Port Chatham?+
The latest water temperature near Port Chatham is about 47°F, from NOAA station 9455500, 16 mi away, at 9:30 PM AKDT. Water temperature drives fish behavior and tells you what to wear in the water, so it's worth checking alongside the tide.
