Redondo Beach, WA
Below is the three-day coastal flood outlook based on provided tide levels, barometric pressures, wind forecasts, and NOAA’s flood likelihood data.
CATEGORY 3
WHAT
Coastal waters are expected to reach a peak tide near 20.7 ft in the early morning. While NOAA forecasts a high flood likelihood percentage (16.3%), barometric pressure is comparatively high (around 1024.8 hPa). Historically, when barometric pressure stays above 1016 hPa and tide height remains below 21 ft, flooding tends to be limited or minor. Because of the elevated pressure and only moderately high tidal levels, significant property damage is unlikely.
WHEN
Highest risk from around 04:30 AM to 06:30 AM PST, near the peak morning tide.
IMPACTS
Minor to moderate coastal water run-up is possible with brief inundation of very low-lying roads and parking areas immediately adjacent to the shoreline. Flood damage to properties is not expected, but tides will be high enough to warrant close monitoring.
• The pressure (above 1024 hPa) reduces the likelihood of significant flooding, even though NOAA gives a relatively high flood likelihood percentage.
• Wind speeds remain low and predominantly from the north or northeast, which lessens onshore push.
• Compared to a past Category 3 event (01/06/2025: tide ~20.68 ft, pressure ~1020.47 hPa), current conditions have even higher pressure. This further supports the Category 3 classification for 2026-01-03.
CATEGORY 3
WHAT
A morning high tide near 20.9 ft is expected, coupled with slightly lower barometric pressure than Day 1 (about 1023.2 hPa), but still well above the very low-pressure readings seen with more severe floods. NOAA projects a higher flood likelihood (20.6%) than Day 1, but given the persistently high pressure and tide staying under 21 ft, serious flooding or property damage appears unlikely.
WHEN
From approximately 05:30 AM to 07:00 AM PST, around the highest tide.
IMPACTS
Minor overwash of water over some low-lying sections of beaches and immediate waterfront may occur. Roads that are very close to sea level could experience short-duration standing water. Widespread property impacts are not expected.
• Though the NOAA flood likelihood percentage is higher than Day 1, barometric pressure remains relatively high, reducing the potential for major coastal flooding.
• Tides are near, but still below, the 21 ft threshold historically linked with more impactful flooding in this area.
• Wind forecasts indicate no strong onshore flow from the west or northwest that would exacerbate surge conditions.
CATEGORY 3
WHAT
Projected peak tide may approach or slightly exceed 20.9 ft again in the morning, and NOAA’s flood likelihood is even higher (28.9%). However, barometric pressure near 1020.5 hPa remains well above the typical low-pressure benchmarks linked to more severe flood events.
WHEN
Primary window of concern is in the early morning (roughly 06:30 AM to 08:00 AM PST) and again late afternoon near the second high tide.
IMPACTS
While the tides are quite high, they are not anticipated to cause large-scale property damage. Minor to moderate roadway ponding and possible short-term inundation of low-lying coastal spots could still occur, so caution is advised.
• Even though the NOAA likelihood percentage has climbed, the relatively high barometric pressure and tides below 21 ft point to only moderate coastal impacts.
• Winds remain more southerly or southeasterly, not the stronger west/northwest onshore flow that can dramatically worsen coastal flooding here.
• Compared with historical Category 4 events (which often combined lower barometric pressures with high tide heights at or above ~20.5 to 21 ft), current conditions indicate a lesser overall threat level.
You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
Categories 1-2: No risk of flooding.
Category 3: Close to a flood event and worth monitoring.
Category 4: Flooding is likely however, it is uncertain if this will cause major property damage.
Category 5: Likely to flood and cause property damage.
Categories 6-7: Extremely high risk of flooding and property damage.
