Solunar fishing periods
| Period | Window | Trigger |
|---|---|---|
| Major | 2:20 pm – 4:20 pm | Moon overhead |
| Major | 2:20 am – 4:20 am | Moon underfoot |
| Minor | 10:06 am – 11:06 am | Moonrise |
| Minor | 7:36 pm – 8:36 pm | Moonset |
Solunar theory holds that fish feed hardest when the moon is overhead or underfoot (major periods) and around moonrise and moonset (minor periods). Today rates Good (3/4) because the moon is waxing crescent.
Best fishing tides today
| Window | Around | Tide height |
|---|---|---|
| 1:15 am – 4:15 am | high tide at 2:45 am | 5.02 ft |
| 6:07 am – 9:07 am | low tide at 7:37 am | 2.63 ft |
| 12:05 pm – 3:05 pm | high tide at 1:35 pm | 6.32 ft |
| 7:02 pm – 10:02 pm | low tide at 8:32 pm | -0.05 ft |
Fish generally feed hardest when water is moving. These are the windows either side of each tide change, when flow is strongest.

Frequently asked questions
What time is high tide at Oakland Middle Harbor today?
The next high tide at Oakland Middle Harbor is at 1:35 pm local time, reaching 6.32 ft above MLLW. The next low tide is at 8:32 pm (-0.05 ft).
How many tides does Oakland Middle Harbor get per day?
Oakland Middle Harbor has mixed semidiurnal tides, which means two highs and two lows a day of noticeably different sizes. This week the paired highs differ by 0.9 ft on average and the lows by 2.8 ft. Times shift roughly 50 minutes later each day as the moon advances, which is why a printable weekly or monthly table is more useful than a single day's times.
When is the lowest tide this week at Oakland Middle Harbor?
The lowest tide at Oakland Middle Harbor in the next seven days is -0.05 ft at 8:32 pm on 2026-10-13. The highest is 6.32 ft at 1:35 pm on 2026-10-13.
What time does the tide turn (slack water) at Oakland Middle Harbor?
Slack water, when the current is weakest, falls roughly midway between a high and a low. Today that is around 5:11 am, 10:36 am, 5:03 pm. These are estimates from the tide times; true slack can lag the turn by up to an hour in a narrow channel or river mouth.
Is this a spring tide or a neap tide at Oakland Middle Harbor?
Tides here are currently between spring and neap. The moon is waxing crescent (8% illuminated). Spring tides, the biggest range between high and low, follow the new and full moon, when the sun and moon pull in line. Neap tides, the smallest range, follow the quarter moons.
What is the tidal range today at Oakland Middle Harbor?
Today's range is 6.4 ft between the highest high and the lowest low. The average daily range here over the next month is about 5.7 ft, so today is larger than usual.
Is there a minus tide at Oakland Middle Harbor today?
Yes, Oakland Middle Harbor has a minus tide today. The 8:32 pm low reaches -0.05 ft, below the MLLW reference level, which is what "minus tide" means. Minus tides expose tidepools, mudflats and shellfish beds that are normally underwater, and are the best windows for tidepooling and clamming.
What time is the lowest tide today at Oakland Middle Harbor?
The lowest tide today at Oakland Middle Harbor is at 8:32 pm at -0.05 ft above MLLW. The lowest predicted tide over the next month at Oakland Middle Harbor is -1.06 ft.
What is the rule of twelfths for tides?
The rule of twelfths estimates how much water moves in each hour of a roughly six-hour tide: 1/12 of the range in the first hour, then 2/12, 3/12, 3/12, 2/12 and 1/12. Water moves fastest in the middle two hours and barely moves near high and low slack. With Oakland Middle Harbor's range today of about 6.4 ft, that is roughly 0.5 ft in the first hour and about 1.6 ft during each of the two middle hours.
What is the best tide for fishing at Oakland Middle Harbor?
Most inshore anglers prefer moving water rather than slack tide, so the two hours either side of a high or low, when the rule of twelfths says flow is fastest, tend to fish best. Using today's predictions, the strongest movement is between 2:45 am and 7:37 am. Local conditions, wind and season matter as much as the tide itself.
Is it better to go to the beach at high or low tide?
Low tide exposes the most sand and the widest walking beach, and is best for tidepooling and shelling. High tide suits swimming and launching boats, though it leaves less dry beach. At Oakland Middle Harbor the difference between the two is about 6.4 ft of water height.
What is the rule of 6 for tides?
"Rule of 6" is another name for the rule of twelfths above. It is the idea that a tide takes about six hours to run, and that the water moves by a different fraction of its range in each of those six hours. Some people also use it as shorthand for the roughly six-hour gap between a high and the next low, which at Oakland Middle Harbor averages about 6.0 hours today.
How accurate are these tide predictions?
The tide times on this page are NOAA's astronomical predictions for station 9414777, typically within about 10 minutes on timing and half a foot on height. They account for the sun and moon but not the weather. A strong onshore wind, a storm surge or unusually high or low barometric pressure can push the real water level well above or below the prediction. Never use them for navigation or life-safety decisions. NOAA's own page for this station carries the official record.
What datum are these heights measured from?
All heights are feet above mean lower low water (MLLW), the standard NOAA tidal datum for US coastal predictions, the average of the lower of the two daily low tides. A reading of 0.0 ft means water at that reference level, and a negative reading means below it.
How warm is the water at Oakland Middle Harbor?
The nearest water-temperature reading to Oakland Middle Harbor is 64 °F (17.8 °C), measured 11:54 am at NDBC buoy OBXC1, 0 miles away. It has risen 1.4 °F in the last 24 hours.
