Hawaii Storm History: Recent Major Weather Events
Published 2026-07-20 · Updated 2026-07-20
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 Storm History: Recent Major Weather Events
Hawaii's climate, predominantly tropical, is often associated with consistent warmth and trade winds. However, severe weather, including strong wind gusts and hail, does occur and can have significant impacts. For property owners, researchers, and insurance professionals, understanding the history of these events is key to accurate date-of-loss research and property assessment.
What are Hawaii's Typical Storm Patterns?
While not as frequent as in the mainland U.S., severe weather in Hawaii typically manifests as strong winds, heavy rainfall, and, occasionally, hail. Tropical cyclones and Kona lows are systems that can bring widespread damaging winds and flooding. Even non-thunderstorm wind events can reach severe thresholds, causing damage to infrastructure and property.
Hail in Hawaii
Hail events are less common in Hawaii compared to other regions, but they do occur. The National Weather Service (NWS) defines severe hail as having a diameter of 1.00 inch (quarter-size) or larger. Even smaller hail, particularly if accompanied by strong winds, can still cause damage, especially to softer roofing materials. Historically, reports of pea-sized (0.25") to mothball-sized (0.50") hail are more frequent, though larger events are not unheard of.
Damaging Winds in Hawaii
Damaging winds in Hawaii can stem from various meteorological phenomena, including thunderstorm downbursts, strong trade winds turbocharged by local topography, and tropical systems. The NWS severe thunderstorm criteria define severe wind gusts as those reaching 58 mph (50 knots) or higher. Wind gusts of 40 mph are considered strong, while gusts exceeding 70 mph are capable of causing significant damage.
How StormAuditor Measures and Estimates Past Weather Events
StormAuditor provides detailed historical weather insights by leveraging a robust methodology for both wind and hail events. We process data from various authoritative sources to offer comprehensive storm reports for any U.S. address.
Hail Estimation (SAHE-2)
StormAuditor's Hail Estimate (SAHE-2) system utilizes radar-derived Maximum Estimated Size of Hail (MESH) data from sources like MRMS via Hail Explorer. This data is cross-referenced with human-observed storm reports from the Storm Prediction Center (SPC) and NWS severe thunderstorm warnings. For a property to be included in a hail report, it must fall within a 0.25-mile buffer of a MESH swath or warning polygon.
Wind Estimation (SAWE-2.9)
StormAuditor's Wind Estimate (SAWE-2.9) methodology creates a detailed background wind field. This is achieved by analyzing High-Resolution Rapid Refresh (HRRR) models and daily peak gust data from available observation stations. This background is then refined using a two-pass objective analysis (Cressman/Barnes) against measured wind gusts from ASOS/AWOS stations and NWS Local Storm Reports (LSRs) that include measured qualifiers. This process allows us to estimate wind speeds at specific locations, considering the local meteorological context.

Recent Notable Storm Days in Hawaii
Based on recent StormAuditor data since March 22, 2026, Hawaii has experienced the following 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 highlight the varied severe weather phenomena that can impact the Hawaiian Islands.
How to Research a Date of Loss in Hawaii
StormAuditor simplifies the process of historical weather research for specific dates and locations in Hawaii. If you need to investigate a potential date of loss, follow these steps:
1. Use the Address Lookup tool: Enter the specific Hawaiian address and the date in question on our /address-lookup page. This will generate a property-specific historical weather report, detailing 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 guides you through a comprehensive workflow to examine weather conditions surrounding a reported damage date.
3. Review historical weather conditions: For general atmospheric conditions, our /weather-on-this-date tool provides insights into precipitation, temperature, and peak wind gusts for any given date.
These tools help you gather the necessary historical weather data to understand the context of potential property damage.
Practical Guidance for Hawaii Residents and Professionals
For homeowners, contractors, adjusters, and attorneys in Hawaii, understanding past weather events is critical for accurate assessments. Using StormAuditor's robust data can help establish baseline weather conditions and identify severe events that may correspond to reported damage. Always remember that while StormAuditor provides comprehensive weather data, a qualified on-site inspection by a trained professional is essential to determine causation of damage.
Limitations
While StormAuditor uses reliable sources and advanced methodologies, it's important to acknowledge certain limitations:
- Radar-derived hail estimates (MESH) can sometimes under-estimate wet hail or over-estimate in areas of very high reflectivity.
- Wind observation stations (ASOS/AWOS) are not everywhere, meaning localized microbursts or small-scale wind anomalies between stations might only be captured if a report was made.
- NOAA severe weather warning polygons indicate an area and time when severe weather was possible; a property within a polygon was under a warning but did not necessarily experience the precise conditions for the entire duration or at the peak intensity.
- StormAuditor provides estimates and historical data; we do not offer legal, insurance, or engineering advice, nor do we determine the cause of property damage. Please refer to 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. While this is just below the 1.00-inch severe hail threshold, it represents a significant recent hail report for the islands.
Q: How do I find storm history for my Hawaii address?
A: You can use StormAuditor's /address-lookup tool. Simply enter your Hawaii address and the date you're researching to receive 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 wind gusts in Hawaii can reach and exceed this threshold, such as 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 comprehensive historical weather data, including 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, which include warnings and reports related to tropical cyclones and other significant weather systems that impact Hawaii. Any severe wind or hail events associated with these systems will be reflected in our reports.
