Boating in a Storm: What You Should Do if Caught in Severe Storm Conditions

Boating in a storm is extremely risky. Some storms, such as hurricanes, allow plenty of time to prepare. Others are not so predictable. Large waves can send passengers overboard, and any storm that produces thunder can result in lightning. Boating in these conditions can easily lead to trouble. In fact, the odds of your power boat being struck by lightning are about 1 in 600, and according to the US Coast Guard, bad weather is responsible for hundreds of boating accidents each year.

Haze can obscure storm clouds, making them practically invisible until you’re close and requiring you to act fast to get to safety. With these boating safety tips, you’ll be prepared for the worst.

Preparedness Is Key

Before you’d find yourself in poor weather, it’s a good idea to carry some essential safety gear and familiarize yourself with weather warnings.

Recommended Equipment for Boating in a Storm

Having some gear on board regardless of the weather forecast means that you’ll have less to think about when prepping for future trips, and you’ll be prepared for non-weather-related emergencies. Win-win.

In addition to your legally required life jackets, there are 3 storm safety essentials: harnesses, a first aid kit, and a VHF radio.

First Aid: Marine first aids kits are a bit different from your standard at-home kits in that they usually come in a waterproof carrier and may have supplies for more serious wounds. Some will include additional gear such as flares and whistles, which could prove necessary if you’re caught in a storm and need help.

Harnesses: Keep these at the ready to secure yourself and passengers. Some life jackets come with them attached, but not all. Harnesses will keep everyone securely on board in the face of large waves.

VHF Radio: “Do I need a VHF Radio on my boat?” It’s a common question in a world of cellphones. To keep it short and sweet, yes. Despite how impressive smartphone tech has gotten, VHF radios beat them with 3 key characteristics: they’re waterproof, have a longer battery life, and can operate without a network. But, that doesn’t mean you have to sacrifice smart technology– Smart VHF marine radios have hit the market, with advanced capabilities and a user-friendly design.

Additionally, if you're on a boat during a thunderstorm, you should consider a lightning grounding system to protect electrical components and prevent injuries. Most smaller boats are made of fiberglass or wood and don’t give lightning a ground, meaning that when lightning strikes, there isn’t a clear path to the surface of the water for the electricity to travel. It therefore “jumps” around the boat, destroying essential (and expensive) electronics, rendering engines unusable, putting holes in the hull, and occasionally causing injury or death.

Grounding systems installed during a boat's initial construction– rather than those added later— are typically more effective in safely guiding the lightning to the water. Still, the addition of a grounding system will only help. You can read about the details of this process on the National Ag Safety Database.

Check the Weather

We’ll admit this may be an obvious one, but it’s important. Checking the marine weather forecast before heading out is the best way to avoid inclement or downright dangerous weather. For information about major weather events, doppler radars, and general warnings for your region, the National Weather Service offers a reference. There are 6 terms you should look out for:

Small Craft Advisory: This indicates a forecast for winds of 18 to 33 knots. Generally, this warning indicates poor conditions for boaters with smaller vessels.

Gale Warning: This indicates a forecast for winds off 34 to 47 knots.

Storm Warning: This indicates a forecast for winds of 48 knots or more.

Tropical Storm Warning: If winds are predicted to reach 34 to 64 knots due to a tropical storm, this warning will be issued.

Hurricane Warning: Similar to the tropical storm warning, a hurricane warning is observed if winds are predicted to reach 64 knots or more due to a hurricane.

Special Marine Warning: This type of warning is issued if a short-term storm with winds over

Once you’re on the water, NOAA broadcasts are your best bet. Their continuous broadcasts include information about the wind speed, wind direction, temperature, humidity, wave conditions, barometric pressure, and more. The broadcasts are local and generally will reach 20 to 40 miles.

NOAA broadcasts operate on three frequencies: 162.400 MHz, 162.475 MHz, and 162.550 MHz. Keep the radio set to one of these channels for updates.

What Should You Do if Caught in Severe Storm Conditions While Boating?

Maybe the forecast has changed dramatically since you last checked, or you’ve encountered a small, localized storm that wasn’t reported. Now, you see the ominous clouds in the distance. And it happens: you are caught in a severe storm in your boat. What should you do?

If you are caught in a storm in your boat, take immediate action to reduce risk and ensure passenger safety.

Before the storm hits:

• Ensure all passengers wear life jackets and harnesses.
• Secure all loose objects to prevent injuries or damage.
• Check your VHF radio and determine your location.

During the storm:

• When boating in a storm, steer at a 45-degree angle to oncoming waves to maintain control and stability.
• Avoid metal objects such as railings or steering wheels. If you're steering a metal wheel, use rubber gloves or a wooden spoon to avoid conductivity.
• Disconnect power cords to protect electronics from lightning strikes.

After the storm:

• Double up dock lines to prevent damage from strong winds.
• Leave electronics unplugged to avoid power surges.
• Remove tarps and canvas covers to reduce wind resistance.

If you’re on a boat during a thunderstorm, you should take every possible precaution to protect yourself from waves, lightning, and high winds.

Look Out for Lightning

Boating in a storm becomes far more dangerous when lightning is involved. As the storm approaches, look for signs that an electrical storm is brewing. Clouds with sharp edges are more likely to produce lightning, as are especially dark clouds.

Consider these warnings and immediately head towards safety if you see this type of storm brewing, bearing in mind that the anvil-shaped clouds point in the direction they’re headed.

Where Should You Seat Your Passengers?

The best place to seat your passengers during a thunderstorm depends on the type of boat you’re in. Lightning, as we all know, seeks the highest point. If you have a covered space or enclosed cabin, this is going to be the safest place to stay.

However, open boats don’t have this option. They can be especially dangerous in electrical storms because you are the highest point. In this case, remove metal jewelry and have passengers get as low as possible. It’s especially important to avoid boating in a storm is these cases– head to the shore if you are in an open boat.

Boating in a Storm: Safety Precautions

You may find that you’ve taken precautions to avoid boating in a storm, yet still you are caught in severe weather. If you haven’t quite beat out the storm, here’s what to do:

• Monitor the Weather: Always check marine forecasts before heading out to avoid sudden storms.
• Have Emergency Gear Ready: Essential items include a VHF radio, first aid kit, life jackets, and harnesses.
• Recognize Storm Signs: Dark, sharp-edged clouds and increasing winds indicate a storm on a boat may be approaching.
• Head to Shore if Possible: If you see ominous clouds in the distance, steer toward safety immediately.
• Navigate Properly: Travel at a 45-degree angle to waves to keep your boat stable.

Boating in a Thunderstorm: How to Stay Safe

If you're on a boat during a thunderstorm, you should:

• Seek enclosed shelter (if available) to avoid direct lightning exposure.
• Remove metal jewelry and accessories to reduce the risk of a lightning strike.
• Stay as low as possible in open boats to avoid becoming the highest point.
• Monitor the direction of the storm’s movement and steer accordingly.

Boating in a thunderstorm requires extra caution, especially for open boats without protective covers.

How to dock your boat safely after a storm on a boat

Once you’ve made it ashore, you may feel that you’re in the clear. There are still a few measures you can take to protect your boat, however.

• Double your dock lines to strengthen them. If your boat is docked in rough waters, they’ll be taking extra stress. Doubling them up prevents them from snapping.
• Leave your electronics unplugged. Although it’s far less likely that lightning is a threat once you’ve reached shore, the risk of power surges is still not zero.
• Keep off canvas covers and tarps. Wind will catch in coverings and cause more tension for your vessel. Use painters’ tape to cover electronics individually with plastic bags, instead.
