Redondo Beach, WA
CATEGORY 2
WHAT
Tides are expected to reach around 16.9 ft near midday with moderately low barometric pressure (~1001–1003 hPa), but NOAA forecasts a 0% flood likelihood. Overall, this indicates no substantial risk of flooding.
WHEN
The highest tide occurs around midday (roughly 12:30–12:45 PM).
IMPACTS
No flooding impacts are expected. Coastal areas and low-lying spots should remain unaffected given the relatively stable atmospheric conditions.
• Historical events with similar tide heights (under 17 ft) have generally not produced coastal flooding unless paired with very low barometric pressure or strong onshore winds.
• NOAA’s official outlook for 08/31 shows a 0% flood likelihood.
• Winds remain light, further reducing any wave or surge influence.
CATEGORY 3
WHAT
Tidal heights may approach or slightly exceed 17.4–17.5 ft in the early afternoon, which is close to historical minor-flood thresholds. However, barometric pressure is forecast to stay above 1003 hPa, and NOAA rates flood likelihood at 0%. This places conditions “close to a flood event” but still unlikely to result in damage.
WHEN
Highest tide is expected in the early-to-mid afternoon (around 1:30–2:30 PM).
IMPACTS
Minor, if any, impacts. Beachgoers should remain aware of higher-than-usual water levels but no damaging inundation is expected.
• The tide height is comparable to past Category 3 events (e.g., 12/27/2023 at ~17.46 ft), which were mostly minor.
• NOAA’s current outlook and relatively modest wind speeds suggest little chance of actual flooding. Continue to monitor if local conditions change.
CATEGORY 3
WHAT
Tide forecasts indicate a peak near 18 ft (about 17.99 ft) around mid-afternoon, which is higher than Day 2 and aligns with previous “close to flood” events. Despite this, barometric pressure (~1005 hPa) is not especially low, and NOAA again assigns a 0% flood likelihood.
WHEN
Peak water levels will likely occur around 2:30–3:30 PM.
IMPACTS
Some low-lying shoreline spots could see very minor pooling of water, but significant property damage or street flooding is not anticipated.
• Although the projected tide is notably high, the atmospheric pressure remains well above the ~992-hPa threshold historically tied to more serious flooding.
• Light winds from generally northern directions decrease the chance of wind-driven coastal flooding.
• Comparison to a past Category 3 event (12/27/2023) shows a similar or slightly higher tide height, but with no accompanying severe weather indicators.
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.
