How should a Hawaii business prepare for IT downtime during hurricane season?

What 2026 actually looks like for Hawaii

NOAA’s 2026 Central Pacific hurricane season outlook forecasts an above-normal season, with five to thirteen tropical cyclones expected in the basin that includes the Hawaiian Islands (NOAA Central Pacific Hurricane Center). The season runs June 1 through November 30, with peak activity historically concentrated in August and September. An above-normal forecast does not predict a direct hit, but it does raise the odds that at least one storm closes enough to disrupt power, internet, or shipping on Oahu and the neighbor islands.

The pattern we see with Hawaii clients is consistent: it is rarely the storm itself that takes a business offline. It is the cascade of secondary effects — a transformer blown out blocks away, a fiber cut, a generator that did not start, a cooling failure in an unconditioned closet during a multi-day heat advisory. Each of those events is survivable with preparation and ruinous without it.

The honest cost of an hour offline

It is easy to underestimate downtime when nothing is currently broken. The numbers from credible 2025 industry surveys are sobering. The joint Calyptix and ITIC 2025 SMB Security Survey of 715 SMB organizations found that 57% of small businesses with 20 to 100 employees report downtime costs above $100,000 per hour, and that 8% of small businesses face downtime costs exceeding $25,000 per hour (Calyptix/ITIC 2025 SMB Security Survey, summarized). For larger SMBs in the 100-plus employee range with $15 million-plus in revenue, documented full-cost downtime reaches $200,000 per hour when lost revenue, idle wages, customer fallout, emergency vendor fees, and reputational damage are all counted.

Hawaii businesses sit at the harder end of that range for the reasons we wrote up in our archive on the real cost of IT downtime for Hawaii businesses: replacement hardware ships from the mainland and can take days or weeks during a regional disruption, on-island vendor capacity is finite and gets booked the moment a storm threatens, and a statewide event hits every supplier and every customer at the same time. The same mechanics show up in our analysis of why Hawaii businesses take longer to recover from cyberattacks. The lesson translates directly to weather events.

The five moves to make before August

1. Actually test a backup restore

The single most common business continuity failure we encounter is a backup job that has been running successfully for years but has never been restored from. A backup that has not been restored is a hypothesis, not a recovery plan. Pick one important system this month — a file share, a database, a line-of-business application — and run a real restore to a sandbox or alternate environment. Time it. Note what went wrong. Fix it before storm season closes the window.

This is the same point we made about backups as an untested strategy: the test is the strategy.

2. Document who decides what when systems are down

During a real outage, the wrong question is “what do we do?” The right question is “who decides?” Write down, on paper, the answers to: who calls the all-staff message, who authorizes overtime, who decides to close a location, who talks to insurance, who talks to customers, who pays an emergency vendor invoice over $10,000 without three signatures. A one-page decision matrix removes the worst kind of recovery time — the kind spent waiting for someone to make a call.

3. Confirm every critical application has a remote-work path

The classic Hawaii outage scenario is that the office loses power but your home does not. That only helps if your staff can actually do their jobs from home. Walk through your top ten business processes and confirm each can be performed remotely: VPN works and has license capacity for a full surge, line-of-business applications are accessible without on-premise dependencies, phone calls forward or route through a softphone, multifactor authentication does not depend on an office device. If two-factor authentication is tied to a hardware token sitting in a desk drawer, that is a discovery worth making in June.

4. Pre-stage replacement hardware for the slow-shipping items

The line between “back online in hours” and “back online in weeks” is usually a single piece of hardware that has to ship from the mainland. Network switches, firewalls, UPS batteries, server-grade drives, and specific replacement parts can be on a several-day shipping clock under normal conditions and a multi-week clock during a regional event. The fix is unglamorous: identify the five or ten items you cannot operate without, and keep a spare on-island. Not a warehouse — a closet. The cost is small. The recovery time benefit is enormous.

5. Run a 90-minute leadership tabletop

Pick a scenario — “Cat 2 storm passes 80 miles south of Oahu, island-wide power outages, ten days to full restoration” — and walk leadership through how the business operates for the next 72 hours. The point is not to produce a perfect plan. The point is to find the three or four wrong assumptions everyone is carrying. A 90-minute meeting in June surfaces them. A real event in September does not give you the same time to react.

What good looks like by mid-July

• A backup restore of at least one production system completed within the last 30 days, with the time-to-restore documented.
• A one-page decision-rights matrix posted where staff can find it without logging into anything.
• A verified remote-work checklist for the top ten business processes — including MFA reset procedures.
• An on-island spares inventory for the five to ten hardware items that have multi-day mainland lead times.
• Tabletop exercise minutes with at least three action items assigned, with names and dates.

None of this requires new software or capital spending. It requires a few half-days from leadership and IT during a quiet stretch. The window between mid-June and mid-July is the right time.

Where this connects to the rest of your IT posture

Business continuity overlaps heavily with cyber recovery. A backup that survives a hurricane should also survive ransomware. A decision matrix for storm response is the same matrix you would use for an incident-response activation. The cyber insurance posture we wrote about earlier — specifically, the requirement to have working, tested backups — is the same control that gets you through the storm. Two threats, one set of preparations.

If you outsource managed IT, ask your provider to walk you through these five items specifically. Generic “we do backups” is not an answer. Restore time targets, on-island spares, and a tested invocation plan are. That is the standard a managed IT provider should meet for any Hawaii business.

FAQ for owners

We’re a 25-person firm. Do we really need a formal plan?

Yes, but a useful plan at that size is two pages, not 50. The decision matrix, the call list, the remote-work checklist, the spares inventory, and the backup test schedule. That is the plan. Anything longer than that at your size will not be read in an emergency, which makes it expensive paper.

Is hurricane insurance the same as business interruption coverage?

No. Property insurance covers physical damage; business interruption coverage compensates for lost income while you are unable to operate. Many small Hawaii businesses are underinsured on the interruption side. Talk to your broker before the season peaks; mid-storm is not a useful time to discover the policy did not include what you assumed.
