Redondo Beach, WA
CATEGORY 3
WHAT
A relatively high tide near 19.9 ft is expected, paired with moderate barometric pressure (around 1006 hPa). Although this is close to known flood thresholds, it is unlikely to cause flood damage based on historical comparisons where tides exceeded 20 ft or pressures fell below 993 hPa to produce more severe events.
WHEN
The highest flood risk period will be around the peak tide, which occurs near 19:42 PST.
IMPACTS
Minor coastal impacts are possible in low-lying areas, but extensive flooding is not anticipated. Brief, localized water pooling could affect some roads and parking areas very close to the shoreline.
NOAA’s forecast indicates a 0.0% likelihood of flooding for 2025-07-13. Comparing this event to past Category 4 or 5 floods reveals that those events usually paired very high tides with lower barometric pressures (< 993 hPa). Since the pressure here is higher and the tide somewhat below 20 ft, the expected severity is noticeably less.
CATEGORY 3
WHAT
Tides could approach 20.0 ft, with barometric pressure around 1000–1001 hPa—still higher than the critical low-pressure benchmarks linked to severe flooding.
WHEN
The highest risk window falls around the morning high tide (near 06:12 PST) and later in the evening.
IMPACTS
Similar to Day 1, only minor coastal impacts are expected, such as short-lived pooling in very low-lying areas. Widespread property damage is unlikely.
Despite a slightly lower barometric pressure compared to Day 1, NOAA’s flood likelihood remains at 0.0%. Historically, Category 4 or worse has required tides over 20.5 ft or significantly lower pressures (< 993 hPa). The present forecast does not meet both conditions.
CATEGORY 3
WHAT
Tides may briefly exceed 20.0 ft in the evening hours, with barometric pressure forecast near 999–1000 hPa. While these conditions are notable, pressures are not at the historically low levels known to trigger significant coastal flooding.
WHEN
Peak tide and the highest potential risk will occur late in the evening (around 20:36 PST).
IMPACTS
Isolated minor flooding of seawalls, beaches, and susceptible low-lying roads is possible. Major or damaging flooding is not expected.
Although the tide height on Day 3 is marginally higher than Days 1 and 2, barometric pressure remains substantially above the 992.8 hPa threshold often associated with severe flood events. NOAA continues to indicate a 0.0% flood chance for this day.
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.
