Fishing forecast for Anchorage, AK

In Anchorage a king salmon run passes through downtown. Ship Creek drops out of the Chugach foothills into Knik Arm, and the fishery there is governed by two clocks at once: the salmon calendar, which is measured in weeks, and the Cook Inlet tide, which moves water fast enough to strand a wader. Both clocks have to line up before a day is worth taking off work.

Best fishing times in Anchorage this week

Majors run an hour either side of the moon crossing the meridian over Anchorage, AK; minors, half an hour either side of moonrise and moonset. Where those widths come from: best fishing times and how we compute these times.

When these windows are not the right tool

Solunar theory is John Alden Knight's 1926 prediction; the ±60 and ±30 minute widths are convention, not calculation. The times are computed astronomy, the claim that fish feed inside them is not. The day rating follows moon phase — identical nationwide, so every city shows it the same. A moving front beats the moon: apps that read pressure.

Tides in Anchorage

Moving water sets the hour here. The NOAA gauge 2 km from the middle of Anchorage publishes 120 harmonic constants. Mean range is 26.2 ft, and the form factor — diurnal constituents over semidiurnal — is 0.23, which is semidiurnal water.

Where to fish in Anchorage

This page is built around Ship Creek, with Cook Inlet and Eklutna Tailrace in reach — both salt and fresh water, about 5 minutes from the middle of Anchorage.

Ship Creek is fished from a bank inside the city, not from a boat. The mud on the Knik Arm side of the mouth is glacial silt and behaves like wet cement on a falling tide, which is why the access ramps and the fishing platform sit above the mouth rather than on it.

Eklutna Tailrace, about forty minutes out along the Glenn Highway, is the local overflow when the Ship Creek bank fills up. It is a controlled release, so the water there stays cold and clear when the creek itself is running silty after rain.

Cook Inlet has one of the largest tidal ranges in the world — routinely over twenty-five feet on a spring tide. A boat left on the wrong part of the beach at high water is a boat sitting on mud six hours later.

Bird Creek sits at Mile 101 of the Seward Highway, about twenty-seven miles down Turnagain Arm, and runs on the same tidal clock as Ship Creek: the state agency puts most silvers in both creeks about two hours before high water or an hour after. On this arm the flood can arrive as a visible wave — a bore tide running ten to fifteen miles an hour.

Returning kings and coho are held in raceways at the William Jack Hernandez Sport Fish Hatchery, on the creek bank inside the city, and stripped for eggs — the fish worked over downstream came out of that building. A public path follows the stretch up to the dam falls.

The rise and the fall are not the same length here: the water climbs for about five and three quarter hours and drains for six and two thirds, so the flood is nearly an hour shorter than the ebb. At Seattle and Charleston the two sides match within ten minutes. Mid-flood on a big tide the level gains close to ten feet in an hour.

The nearest grids we publish are Seattle, WA (2309 km, Puget Sound) and Portland, OR (2478 km, Columbia River). Different water, and different minutes.

What you can catch in Anchorage

State listings put these 5 fish in the water around Anchorage. Plan around the peak, not the open season.

Two salmon runs stack in the same water on different calendars: kings in June, silvers from late July into September. A week either side of those windows and the creek holds Dolly Varden and stocked rainbows instead, which changes the tackle far more than the time of day does.

Halibut is a Cook Inlet fish, not an Anchorage-shoreline fish. It is on the local list because charters run out of Homer and Seward, three to five hours away, and the summer bite follows the same June-to-August pattern the salmon runs sit inside.

Nothing in the Anchorage bowl is a year-round fishery. Outside the weeks a run or a stocking truck sets, the water is not slow — it is empty.

More than two dozen lakes inside the Anchorage bowl are stocked — rainbow trout, Arctic char, Arctic grayling and landlocked chinook, the same species as the kings in Ship Creek but fish that never reach salt water or that size.

Northern pike are invasive in Southcentral Alaska and were put into Anchorage lakes illegally. Cheney Lake held the most popular rainbow trout fishery in the city until pike appeared there around 2000; stocking was abandoned rather than feed hatchery trout to them, and trout went back only after the lake was treated with rotenone in 2008.

Nothing off this mouth is found by sight. Glacial flour off the Knik and Matanuska rivers keeps the arm opaque brown, and the suspended load is heaviest at the low stages of the tide, so fish work the creek by scent and by the push of the flood.

Water temperature and season in Anchorage

Air here swings 42.7 °F across the year, from 16.9 °F in January to 59.6 °F in July, and November–March average below freezing. Water is measured separately, and it is not the same number: against these air normals the gauge reads 13.4 °F warmer in January and 3.0 °F colder in April.

Monthly climate for Anchorage, AK. The air line is the NOAA NCEI climate normal for 1991–2020 — the thirty-year average of a calendar month, not the weather of any one year — measured at ANCHORAGE INTL AP, AK US (USW00026451), 8.9 km from the middle of town, with 27–29 of the thirty years behind each month. The water line is neither a normal nor the air: hourly readings at NOAA gauge Anchorage (9455920), 2 km out, averaged by calendar month over 2015–2025 — 10–11 complete years per month. It is the surface at the gauge, not the water on any particular spot, and it lags the air by weeks, so the two lines are not interchangeable. Read into this site on 2026-08-13.

Salt water freezes below thirty-two degrees, and from December into March the arm sits pinned on its own freezing point, near thirty, while the air runs far colder still. July, the warmest month at the gauge, averages fifty-eight. Neither threshold this site leans on elsewhere — sixty for a bass spawn, seventy where trout suffer — is a monthly average here. Heat gates nothing in Anchorage; run timing and ice do.

Sunrise, sunset and daylight in Anchorage

The moon window moves daily; the sun does not. Plan a season against this block.

The longest day of 2026 is June 20, 19h 22m; the shortest, December 21, 5h 27m. The meridian passing drifts about 50 minutes later daily: a dawn window this week is an afternoon window in a fortnight.

Anchorage sits at 61 degrees north, and daylight, not the moon, is the dominant variable here. Late June gives more than nineteen hours between sunrise and sunset; late December gives under five and a half. No other city in this grid swings by anything close to that.

Freeze-up on the lakes around town usually starts in late October and ice fishing runs into April, so the open-water year here is shorter than the calendar year by roughly a third. That compresses everything else on this page into a narrow season.

Midsummer here is not merely long, it never goes properly dark. Around the solstice the sun sinks less than five degrees below the horizon at its lowest, so the sky holds civil twilight all night and a major period at two in the morning is still fishable light.

Winter is as extreme in the other direction: at midwinter the sun reaches only about five and a half degrees above the horizon at noon, so the whole short day is flat light with no real morning or afternoon to it. Around the equinoxes day length shifts by close to six minutes every twenty-four hours.

Salt water here does not lock up the way the lakes do. Ice forms in Knik Arm all winter, but the tide breaks it up and runs it along the arm twice a day, so the shore off the creek mouth is a shifting floe field, not a solid lid.
