Redondo Beach, WA
CATEGORY 2
WHAT
High tides are expected to reach around 17.8–18.4 ft. Barometric pressure is projected above 1006 hPa during these peaks, which is not sufficiently low to create substantial flood concerns. NOAA’s Flood Likelihood is reported as 0.0%, indicating minimal risk.
WHEN
The highest-risk tidal periods are near 06:24 AM and 08:42 PM PDT, but neither is predicted to exceed thresholds observed in more flood-prone historical events.
IMPACTS
Because water levels remain below the more significant flooding thresholds and barometric pressure is not critically low, no flooding is anticipated in most low-lying areas.
• Historical Comparison: On 12/27/2023, a tide of 17.46 ft with a pressure of 1006.1 hPa was categorized as a Category 3 event—but it had a higher NOAA Flood Likelihood (8.4%). The latest NOAA guidance for 04-06 indicates a 0.0% likelihood of flooding, suggesting less overall risk.
• Wind Direction & Speed: Forecast winds are relatively light and mostly from southerly directions, which typically do not push as much water toward the Redondo Beach shoreline compared to strong W/NW wind events.
CATEGORY 3
WHAT
Tides are expected to peak near 18.1 ft during the late evening, and barometric pressure could drop to around 1002.6 hPa—moderately low by local standards. This combination approaches conditions seen in minor flood-potential scenarios.
WHEN
Primary concern around 09:00 PM–10:00 PM PDT when water levels crest and pressure is at its lowest.
IMPACTS
Although property damage is unlikely, some low-lying or poorly drained areas could see brief standing water. Minor inundation in shoreline access areas is possible but is not expected to cause significant disruptions.
• Historical Comparison: A tide around 17.46 ft with ~1006 hPa pressure in December 2023 was Category 3; Day 2’s slightly higher tide (around 18.1 ft) but somewhat lower pressure is a similar or marginally higher concern.
• NOAA CO-OPS Flood Likelihood remains 0.0%, indicating official modeling does not anticipate widespread flooding. However, lower pressure warrants closer monitoring overnight.
CATEGORY 2
WHAT
Morning and afternoon high tides (near 16.8 ft max) coincide with moderately low barometric pressure (around 1002.7 hPa). While the pressure is on the lower side, tide heights are not expected to exceed levels typically associated with coastal flooding.
WHEN
Peak high tides are around 07:36 AM and again mid-afternoon (roughly 04:42 PM PDT), though both remain well below historically significant flood levels.
IMPACTS
Mainly negligible impacts; no notable flooding is expected. Local beach and marina areas will see higher water than average, but inundation of roadways or property is not anticipated.
• Tides & Pressure: Although the pressure is similar to Day 2, tides are notably lower (under 17 ft vs. ~18 ft).
• Historical Benchmark: Much lower sea levels than Category 4 or 5 historical events (which exceeded 19–22 ft).
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.
