Crowd safety during adverse weather conditions

Recent conditions have served as a timely reminder of how quickly weather can change. From prolonged periods of sunshine to sudden downpours and thunderstorms, event organisers must be prepared for a range of weather-related challenges. As the likelihood of heavy rain and thunderstorms increases, it is essential for event organisers to assess whether their events are adequately prepared to manage adverse weather conditions safely and effectively.

Key Questions to Consider:

Has an adverse weather risk assessment been completed?

Are procedures in place to monitor weather forecasts and severe weather warnings throughout the event?

Have suitable shelter and refuge areas been identified for attendees, staff, and contractors?

Are event grounds, walkways, and access routes capable of managing heavy rainfall and preventing slips, trips, and falls?

Have electrical installations, temporary structures, and staging been assessed for use during wet and stormy conditions?

Have staff been briefed on emergency procedures relating to severe weather, including thunderstorms and lightning?

Are contingency and evacuation plans in place should weather conditions deteriorate rapidly?

Adverse Weather Safety Checklist

• Monitor weather forecasts and warning systems before and throughout the event.

• Establish clear communication procedures to inform attendees, staff, and contractors of developing weather conditions.

• Provide suitable sheltered areas for protection from heavy rain and thunderstorms.

• Ensure drainage systems, walkways, and high-traffic areas are inspected and maintained to reduce flooding and slip hazards.

• Secure temporary structures, signage, fencing, and equipment against strong winds and storm conditions.

• Review electrical safety measures and protect power supplies, cables, and equipment from water ingress.

• Confirm emergency response teams and first aid providers are prepared to manage weather-related incidents.

• Develop and communicate clear evacuation, shelter-in-place, or event suspension procedures if severe weather poses a risk to public safety.

• Consider the needs of vulnerable individuals, including children, older adults, and those with mobility or medical requirements.

Remember

Heavy rain, strong winds, and thunderstorms can present significant risks to everyone on site, including event staff, contractors, performers, volunteers, and attendees. Effective planning, continuous monitoring, and clear communication are essential to reducing risk and maintaining a safe event environment.

Preparation is key — a successful event is one that remains safe, resilient, and ready for whatever the weather brings.
