If you hear thunder, the water is not the place to wait

Thunder is the sound produced by lightning, so a rumble is not merely a sign that a storm may arrive later. It confirms lightning has occurred close enough for you to hear it. Lightning can strike well away from the rain shaft or darkest cloud, including where the sky above the launch ramp, shoreline, or boat still looks partly clear. That is why a dry deck, calm water, or distant-looking storm is not a reason to continue.

For anglers, the exposure problem is immediate. Water, open shorelines, docks, rods, boat rails, and a person standing upright can all leave little margin when a thunderstorm is nearby. Metal does not summon lightning, but it can conduct electrical current, and holding a rod above shoulder height adds to the danger of being exposed in an open area. The practical rule is simple: the first thunder is a SKIP signal for being outdoors, not a cue to squeeze in a few more casts.

The preferred shelter is a substantial enclosed building with electrical wiring or plumbing. If one is not available, use a fully enclosed, hard-topped vehicle with the windows up. The protective value comes from the enclosed structure or vehicle body, not from simply having a roof overhead. Make the shelter choice before launching, because a shelter that is several minutes away can become unreachable once wind, rain, waves, or poor visibility arrive.

Do not substitute a tent, pop-up canopy, open-sided pavilion, picnic shelter, lean-to, porch, carport, open garage, golf cart, ATV, or convertible for lightning shelter. Do not wait beneath a tree, even if it is the closest cover. If you reach a building, stay away from windows, exterior doors, corded phones, plugged-in electrical equipment, and plumbing until the storm threat has passed. A dry roofed structure is not automatically a safe one.

Build the exit decision into the trip plan while conditions are calm. Before departure, check the forecast for thunderstorms, including the timing and location of the risk, and identify the nearest real shelter from each place you may fish. Forecasts describe expected conditions, not a guarantee that a storm will or will not form over your exact water. Continue to observe the sky, listen for thunder, and monitor official weather information during the trip.

A forecast that includes thunderstorms should lower the trip’s margin for error, particularly on open water or at a remote bank with a long walk back to the vehicle. Choose a shorter route, remain near a protected landing, or postpone. If storms begin building, wind shifts or gusts increase, clouds darken, or distant lightning is visible, head in before thunder forces the decision. A MAYBE trip becomes a SKIP when safe shelter cannot be reached promptly and reliably.

When thunder is heard from a boat, head for shore and safe shelter immediately; do not remain on the water to watch the storm’s direction or finish a drift. Thunderstorms can also bring abrupt gusts, changing waves, heavy rain, and reduced visibility, making travel harder as the threat grows. Get off the boat, move away from the shoreline, and continue to a substantial building or enclosed hard-topped vehicle rather than stopping under a dock roof or a small open structure.

If reaching shore is impossible, there is no action that makes an exposed small boat safe from lightning. Continue working toward the best available shelter and avoid touching metal and electrical components as conditions allow. A cabin may offer more protection than remaining exposed, but it does not turn a storm into acceptable fishing weather. This is an emergency risk-reduction situation, not a reason to stay out. The conservative decision remains to get ashore before the storm arrives.

Do not resume fishing when rain weakens, wind eases, or the nearest dark cloud appears to move away. Wait at least 30 minutes after the last sound of thunder before leaving safe shelter or returning to the water. Restart that 30-minute wait if another rumble is heard. This delayed return matters because lightning can remain a threat on the trailing edge of a storm, when people are often tempted outside by improving conditions.

Use a clear trip call: GO only when no thunderstorm threat is expected during the usable fishing window and safe shelter remains practical; MAYBE when storms are possible but you can shorten the trip, monitor conditions, and reach real shelter without delay; SKIP when thunder is heard, lightning is seen, storms are approaching, or shelter is not close enough. If lightning strikes someone, call 911 immediately. A lightning victim does not retain an electrical charge and is safe to touch while you provide aid if it is safe to do so.
