Lightning Safety Around Water: What Parents and Swimmers Should Know

A recent lightning incident at Pasir Ris Beach is a tragic reminder that water safety is not only about swimming ability.

According to The Straits Times,

a man in his 20s was taken unconscious to hospital after being struck by lightning while participating in water activities at Pasir Ris Beach on 5 July 2026. Several others who were kayaking and paddleboarding were also taken to hospital after the incident.

For parents, swimmers and coaches, this is an important reminder:

When lightning risk is present, get out of the water and move to proper shelter. No lesson, activity or booking is worth the risk.

Water Safety Is More Than Swimming Skills

Many parents send their children for swimming lessons so they can become more confident and safer around water. That is important.

But swimming ability alone does not protect someone from every water-related danger.

A child may be able to swim well, float, tread water or perform survival skills. However, if there is lightning risk, the correct action is not to continue swimming. The correct action is to leave the water immediately.

This applies to swimming pools, beaches, reservoirs, water parks and open-water activities such as kayaking, paddleboarding and sailing.

Why Lightning Is Dangerous Around Water

Lightning is especially dangerous around water because swimmers and water-activity participants are often in open and exposed areas.

At beaches, pools and reservoirs, there may be fewer safe shelter options nearby. People in the water or standing around the pool deck may also be exposed to the surrounding environment.

Singapore also experiences frequent thunderstorms and lightning. The Meteorological Service Singapore states that Singapore experiences about 167 thunderstorm days and 176 lightning days a year on average.

This means lightning safety is not a rare concern in Singapore. It is something every parent, swimmer and coach should take seriously.

Clear Sky Does Not Always Mean Safe

One common mistake is assuming that it is safe to continue swimming if there is no heavy rain.

That is not always true.

The Meteorological Service Singapore explains that most lightning strokes occur within 5 to 6km of a thunderstorm cloud, but lightning from a distant thunderstorm cloud more than 10km away could still affect a location.

In simple terms, the weather above the pool or beach may look manageable, but lightning risk can still exist nearby.

This is why swimmers should not wait for heavy rain before leaving the water. If there is lightning risk, thunder, or an official warning, the activity should stop.

What Parents and Swimmers Should Do

Before heading for an outdoor swim lesson or water activity, check the weather.

In Singapore, parents can refer to official weather updates from the Meteorological Service Singapore and the myENV app. The MSS website also provides lightning information, including cloud-to-ground lightning observations.

During a swim lesson or water activity, follow this simple rule:

• If there is lightning risk, stop the activity, leave the water and move to proper shelter.

• Do not wait until the rain becomes heavy.

• Do not stay in the pool because the lesson is almost over.

• Do not continue just because the sky still looks bright.

• Do not assume that being a strong swimmer makes it safe.

What Counts as Safer Shelter?

When lightning risk is present, swimmers should move away from the water and exposed areas.

A safer shelter is usually a proper enclosed building or a designated sheltered area advised by the facility operator.

Avoid waiting in unsafe areas such as:

• Inside the swimming pool

• Beside the pool edge

• On wet open ground

• Under tall isolated trees

• In open fields

• Near metal structures

• At unsheltered beaches or open-water areas

Parents should also keep younger siblings away from the pool deck or open areas while waiting for updates.

How SoS Handles Bad Weather

At School of Swimology, Safety comes before lesson completion.

We understand that parents make time to bring their children for lessons. We also understand that weather interruptions can be frustrating, especially when families have planned their day around the class.

But when lightning risk is involved, the responsible decision is always to pause, delay or stop the lesson.

A swimming lesson can be rearranged. A safety incident cannot be undone.

Our coaches will always prioritise the safety of swimmers, parents and staff when weather conditions are unsafe.

A Reminder for Every Water-Activity Family

The Pasir Ris incident is a painful reminder that water safety must include weather awareness.

Swimming lessons help children become more confident, capable and safe in the water. But true water safety also includes knowing when not to enter the water.

Before any outdoor water activity, check the weather.

During the activity, stay alert.

When lightning risk is present, leave the water immediately.

Be water-smart. Be weather-smart. Stay safe.
