Hawaii Storm History: Recent Major Weather Events
By StormAuditor Editorial Team · Published 2026-07-20 · Updated 2026-08-11
Based on public NOAA and National Weather Service records, published under StormAuditor's methodology and data-source standards. Radar-derived hail sizes are estimates unless attributed to a ground report.
Damage-threshold ranges in this article are general guidance synthesized from industry and federal research — IBHS building-performance research, NWS severe criteria, and product standards such as UL 2218 (hail impact resistance) and ASTM D3161/D7158 (shingle wind ratings). Actual performance depends on product rating, age, installation quality, exposure, and impact characteristics — thresholds describe when damage becomes possible, not when it occurs.
Hawaii, known for its mild climate, can still experience significant weather events, from powerful wind gusts to impactful hail. Understanding these past storms is crucial for research and property assessments.
Hawaii's climate is mostly tropical. People link it with steady warmth and trade winds. Yet severe weather still happens here. Strong wind gusts and hail can have major impacts. Property owners, researchers, and insurance professionals need this event history. It supports accurate date-of-loss research and property assessment.
What are Hawaii's Typical Storm Patterns?
Severe weather is less frequent here than on the U.S. mainland. When it comes, it usually brings strong winds, heavy rainfall, and sometimes hail. Tropical cyclones and Kona lows can bring widespread damaging winds and flooding. Even non-thunderstorm wind events can reach severe thresholds. They can damage infrastructure and property.
Hail in Hawaii
Hail is less common in Hawaii than in other regions, but it does occur. The National Weather Service (NWS) defines severe hail as 1.00 inch (quarter-size) or larger in diameter. Smaller hail can still cause damage, especially with strong winds. Softer roofing materials are most at risk. Historically, reports of pea-sized (0.25") to mothball-sized (0.50") hail are more frequent. Larger events are not unheard of.
Damaging Winds in Hawaii
Damaging winds in Hawaii come from several weather causes. These include thunderstorm downbursts, strong trade winds boosted by local terrain, and tropical systems. The NWS severe thunderstorm criteria set severe wind gusts at 58 mph (50 knots) or higher. Gusts of 40 mph count as strong. Gusts above 70 mph can cause major damage.
How StormAuditor Measures and Estimates Past Weather Events
StormAuditor gives detailed historical weather insights. We use a strong method for both wind and hail events. We process data from trusted sources to build full storm reports for any U.S. address.
Hail Estimation (SAHE-2)
StormAuditor's Hail Estimate (SAHE-2) system uses radar-derived Maximum Estimated Size of Hail (MESH) data. Sources include MRMS via Hail Explorer. We cross-check this data against human-observed storm reports from the Storm Prediction Center (SPC) and NWS severe thunderstorm warnings. To appear in a hail report, a property must fall within a 0.25-mile buffer of a MESH swath or warning polygon.
Wind Estimation (SAWE-2)
StormAuditor's Wind Estimate (SAWE-2) method builds a detailed background wind field. We do this by analyzing High-Resolution Rapid Refresh (HRRR) models and daily peak gust data from available observation stations. We then refine this background with a two-pass objective analysis (Cressman/Barnes). It uses measured wind gusts from ASOS/AWOS stations and NWS Local Storm Reports (LSRs) with measured qualifiers. This lets us estimate wind speeds at specific locations, using the local weather context. For more technical details, see our /methodology/wind and /methodology/hail pages.
Recent Notable Storm Days in Hawaii
Based on recent StormAuditor data since March 22, 2026, Hawaii has seen these significant weather events:
- April 9, 2026 — 4 NW Schofield Barracks — 69.0 mph measured non-thunderstorm wind gust
- March 23, 2026 — 1 N Keaau — 0.75 inch measured hail
These recent storm reports show the varied severe weather that can hit the Hawaiian Islands.
How to Research a Date of Loss in Hawaii
StormAuditor makes historical weather research simple for specific dates and places in Hawaii. Need to investigate a possible date of loss? Follow these steps:
1. Use the Address Lookup tool: Enter the Hawaiian address and the date in question on our /address-lookup page. You will get a property-specific historical weather report. It lists any recorded hail, wind, and NOAA warnings for that location.
2. Explore the Date of Loss Research workflow: Our /date-of-loss-weather-research tool walks you through a full workflow. It helps you review weather conditions around a reported damage date.
3. Review historical weather conditions: For general conditions, use our /weather-on-this-date tool. It shows precipitation, temperature, and peak wind gusts for any date.
These tools help you gather the historical weather data you need. They give context for possible property damage.
Practical Guidance for Hawaii Residents and Professionals
Homeowners, contractors, adjusters, and attorneys in Hawaii all rely on past weather facts. Accurate assessments depend on them. StormAuditor's robust data can help set baseline weather conditions. It can also flag severe events that may match reported damage. One caution: StormAuditor provides full weather data, but only a qualified on-site inspection by a trained professional can determine the cause of damage.
Limitations
StormAuditor uses reliable sources and advanced methods. Still, some limits apply:
- Radar-derived hail estimates (MESH) can sometimes under-estimate wet hail. They can also over-estimate in areas of very high reflectivity.
- Wind observation stations (ASOS/AWOS) are not everywhere. Localized microbursts or small-scale wind anomalies between stations might only be captured if a report was made.
- NOAA severe weather warning polygons mark an area and time when severe weather was possible. A property inside a polygon was under a warning. It did not necessarily experience the exact conditions for the whole time or at peak intensity.
- StormAuditor provides estimates and historical data. We do not offer legal, insurance, or engineering advice. We do not determine the cause of property damage. Please see our full /limitations page for more details.

FAQ
Q: When was the last major hail storm in Hawaii?
A: According to recent StormAuditor data, a 0.75-inch hail event was reported on March 23, 2026, 1 N Keaau. This is just below the 1.00-inch severe hail threshold. Even so, it stands as a significant recent hail report for the islands.
Q: How do I find storm history for my Hawaii address?
A: Use StormAuditor's /address-lookup tool. Enter your Hawaii address and the date you're researching. You will get a property-specific historical weather report.
Q: What is considered a severe wind gust in Hawaii?
A: The National Weather Service defines a severe wind gust as 58 mph or higher. Non-thunderstorm gusts in Hawaii can reach and exceed this threshold. One example: the 69 mph gust reported 4 NW Schofield Barracks on April 9, 2026.
Q: Can StormAuditor tell me if my roof was damaged by a storm?
A: StormAuditor provides full historical weather data. That includes estimated hail sizes and wind speeds at your location. However, we do not determine damage causation. A qualified professional inspection is always recommended to assess property damage.
Q: Are tropical cyclones included in StormAuditor's data?
A: Yes. StormAuditor processes data from sources like the NWS and NOAA. These include warnings and reports tied to tropical cyclones and other major weather systems that impact Hawaii. Any severe wind or hail events from these systems will appear in our reports.
