The sun and moon behind these tides
This station sits away from any city with its own sun and moon pages, so there are no local times to link to. The tides here are still the moon's doing, with the sun adding to or working against it — which is what the simulator shows.
Also see the Sun, Earth & Moon movement simulator, to watch how the three move together over a day, a week or a month.
Next king tides
The biggest predicted tides of the coming year at this station, and the lowest-water windows that typically follow — periods with some of the highest predicted astronomical tides of the year. Consult official local forecasts and alerts before planning any beach, boating or shoreline activity.

What the tides are like at Juneau
Juneau has two high tides and two low tides most days — a mixed tide pattern, cycling at uneven intervals. The two highs (and two lows) each day are often noticeably unequal — a higher high and a lower high. The tidal range here is among the largest in the United States — Cook Inlet near Anchorage can swing 26 to 30 feet. For the exact heights and times today, read them straight off the live chart above — it's drawn from NOAA's harmonic prediction for this station.

About this station
NOAA station 9452210 (Juneau) sits at 58.30, -134.41 on the Alaska coast. Predictions on this page come straight from NOAA's harmonic model for this station — heights in feet above MLLW, times in the station's local time. Conditions a few miles along the shore can differ, so pick the station nearest where you'll actually be.

How many tides a day does Juneau, AK get?
Juneau typically gets two high tides and two low tides each day — a mixed pattern. Exact times for today are on the live chart above.
What is the tidal range at Juneau, AK?
The range between low and high water at Juneau is among the largest in the United States — Cook Inlet near Anchorage can swing 26 to 30 feet. The chart above shows the exact predicted heights for the days you pick, straight from NOAA station 9452210.
Where does the tide data come from?
Straight from NOAA CO-OPS, the official U.S. source for tide predictions — for Juneau, AK it uses the NOAA station listed above. Heights are in feet above MLLW (mean lower low water, the standard chart datum) and times are shown in the station's own local time.
How far ahead can I see the tides?
Tide predictions are computed from astronomy (the positions of the moon and sun), so they're available about a year ahead. Use the date-range finder to list every high tide between any two dates — for general reference and low-risk scheduling only. Before any marine or shoreline activity, confirm conditions with official local forecasts, alerts, harbor guidance, and NOAA.
What is a king tide?
An informal name for the highest tides of the year, which happen when a new or full moon lines up with the moon's closest approach to Earth. In the finder, the top 10% highest tides in your range are marked with a crown — periods with some of the highest predicted astronomical tides of the year.
What actually makes the tide bigger or smaller?
The engine is gravity: the moon and sun pull the ocean into bulges. When they line up at a new or full moon you get the biggest swings (spring tides); at quarter moons their pulls partly cancel (neap tides), and the moon's closest approach (perigee) super-sizes things further — that's a king tide. River flow, the shape of the bay, and long-term sea-level cycles can also affect the actual water level, which is why real conditions can differ from the astronomical prediction shown here.
What are the highest tides in the world — and in the U.S.?
The world's largest tides are in Canada's Bay of Fundy, where the range between low and high can top 50 feet (it's outside NOAA's network, so it isn't listed here). In the U.S., the giants are Alaska's Cook Inlet — Anchorage sees swings around 26–30 feet — along with Southeast Alaska ports like Skagway, and on the East Coast, Eastport, Maine at roughly 18 feet. All of those have dedicated pages here.
Can I save my home beach and other spots I follow?
Yes — tap ＋ Add to Saved Stations next to any station's name (it turns into a green Saved note), or ＋ Add nearest inside the Saved Stations dropdown to add the station closest to you (allow location access). Your saved spots appear as one-tap cards on the tides home page, the Default column's radio button picks your primary station, and Edit removes stations. Everything is stored on your device; no account needed.
