Weather, lightning and open water
Safety · Last reviewed 2026-08-10
An angler on open water or an open bank holding a long carbon rod is a poor place to be in a thunderstorm, and the decision that matters is made before the storm arrives.
Safety
Weather and lightning — Can cause serious injury or death
An angler on open water or an open bank, holding a raised carbon rod, is struck or is close to a strike.
What reduces it: Check the forecast and leave before a storm arrives. If thunder is audible, put down long conductive objects, move away from the water's edge and avoid isolated tall objects and umbrellas.
Boat safety — Can cause injury needing treatment
Deteriorating wind and sea state catch a small boat too far from shelter to return comfortably.
What reduces it: Plan around the forecast rather than the current conditions, and set a turn-back time before leaving.
Lightning risk to anglers is low in absolute terms and high in consequence, which is the combination people handle worst. The exposure is specific: open water, open bank, and a long conductive object held above the head.
Carbon fibre conducts. A modern rod is not a lightning rod in the technical sense, but it is a raised conductive object attached to a person, and that is the geometry that matters.
The practical point is that the decision is made early. Once a storm is overhead the options are poor; the useful action is to have watched the forecast, recognised building conditions, and left before it arrived. Boats compound this because leaving takes time.
What to do when it is already close
If thunder is audible, the storm is close enough to matter. Put down long conductive objects rather than carrying them, get off open water and away from the water's edge, and avoid isolated tall objects such as single trees.
A vehicle with a metal roof is substantially better than open ground. A fishing shelter or umbrella is not — an umbrella is a raised conductive object with a person under it.
On a boat, the priority is getting off the water, and that takes time nobody has once a storm is overhead. This is why the decision is made on the forecast rather than on the sky.
What this page will not do is offer a distance rule that implies safety. Counting between flash and thunder tells you roughly how far away a strike was; it does not tell you where the next one will be.

The larger weather risk is not lightning
For most anglers, wind and sea state cause far more harm than lightning does. Offshore wind on a small boat, a rising sea on a shore mark, and deteriorating visibility all produce more incidents than strikes.
That is worth stating plainly on a page about lightning, because attention is finite and directing all of it at the dramatic hazard leaves the common one unwatched. Checking the forecast for wind and sea state is a higher-yield habit than watching for storms.

Water where it matters
- Open oceanOffshore fishing removes the option of leaving quickly.
- Surf beachesOpen beaches offer no shelter from either lightning or the deteriorating sea state that more often causes harm.
- Tropical estuary and tidal creekBuild-up and wet-season storms arrive fast and a small boat on open water is the tallest thing for a considerable distance.

Places where it matters
- Fiji and MelanesiaTropical cyclones affect the region seasonally and are severe, damaging reefs and villages and suspending fishing for extended periods.
- FloridaFlorida records more lightning strikes than anywhere else in the United States, and an angler on an open flat is the highest point over water.
- KoreaTyphoons reach the peninsula from midsummer into early autumn and the East Sea generates heavy winter storms, both of which fall hardest on small-boat and island fishing.
- Lake Victoria and the Rift Valley lakesAfternoon and night squalls on water this large arrive with little warning and there is frequently no shelter within reach.
- PatagoniaThe southern westerlies can raise a steep breaking sea on a large glacial lake within a short time, and the shore may be a long way off with no shelter along it.
- ShetlandShetland is among the windiest places in Britain with gale frequency to match, and weather changes fast at this latitude with very short winter days.
- The Agulhas CurrentA rapid south-westerly change arriving on an established current is the condition that has caused most losses here, and it can turn a workable sea into a lethal one within an hour.
- The Gulf of MexicoSummer afternoon thunderstorms develop rapidly over a shallow enclosed sea and produce severe conditions and lightning with very little warning.
