Redondo Beach, WA
CATEGORY 3
WHAT
High-tide levels will approach approximately 20.0 ft around the early morning hours (near 05:24), combined with a moderate barometric pressure around 1009.8 hPa and winds near 10 mph from the SSW. While these conditions are relatively high compared to normal, they are not expected to produce major property damage.
WHEN
Highest risk during peak high tide early in the morning (around 05:00–06:00).
IMPACTS
Minor coastal flooding in typically low-lying areas is possible. Temporary ponding of water on roads immediately adjacent to the shoreline could result in brief travel disruptions.
• Compared to historical Category 4 events that featured similarly high tides but also stronger winds and/or lower barometric pressures, today’s conditions fall in line more with historical Category 3 patterns (e.g., 01/06/2025).
• Wind speeds are moderate, and NOAA indicators (though not explicitly provided for 03/31) are generally low. This further supports a below-major-flood threshold evaluation.
CATEGORY 3
WHAT
High tides are expected near 19.8 ft early in the morning (06:00) and around 19.2 ft in the evening (19:54). Barometric pressures at these times (approximately 1011.7 hPa and 1020.5 hPa, respectively) are relatively stable to high, with no significant low-pressure system present. NOAA’s daily Flood Likelihood is listed as low (0.0%).
WHEN
Morning: 05:30–06:30 for highest tides.
Evening: Around 19:00–20:00 for secondary tidal peak.
IMPACTS
Minimal flooding potential in vulnerable, low-lying coastal roads, docks, and walkways. No major impacts are anticipated, but residents should be aware of the possibility of mild overflow at high tide.
• Although 19+ ft tides are significant, they remain below thresholds typically associated with major coastal flooding in Redondo Beach.
• NOAA’s 0.0% flood likelihood and the absence of noteworthy low-pressure conditions keep the flood category lower than historic Category 4 or 5 events.
CATEGORY 3
WHAT
Morning high tide is around 06:36, near 19.3 ft, and an afternoon/evening high tide near 16:12 (roughly 19.0 ft). Pressure is forecast around 1017 hPa, which is moderately high. Winds are generally light to moderate. NOAA again indicates a low (0.0%) likelihood of any coastal flood event.
WHEN
Morning: Approximately 06:00–07:00 for the peak high tide.
Afternoon/Evening: Mid to late afternoon, though slightly lower than the morning peak.
IMPACTS
Minor nuisance flooding may be observed along very low-lying areas near the shoreline. Though water levels are elevated, no major damage is expected. Possible brief interruptions on waterside roads.
• Historically, Category 3 events in Redondo Beach often happen around 19–20 ft tides with moderate or higher barometric pressure. These Day 3 conditions align well with past moderate (Category 3) flood occurrences (e.g., 12/27/2023).
• NOAA’s continuing low flood likelihood and relatively calm winds support only minor coastal impacts.
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.
