Globally, festival organisers face a fundamentally changing risk landscape

For decades, weather risk was mostly predictable and manageable at a local level. Today, extreme weather — from intense flooding and prolonged heat to wildfires and compound climate perils — is reshaping how events are planned, insured, and operated worldwide.

57%

of disrupted events involved weather made more severe or more likely by climate change (2004–2024)**

75%

of outdoor event losses are weather-driven (2021-2026)*

Marsh recommends that organisations focus on seven priorities to help build their operational resilience.

  1. Understand your specific regional risks and seasonal weather patterns — not generic climate change, but local precipitation, temperature, drought, and fire patterns
  2. Assess the capabilities of historical infrastructure to handle current and projected weather extremes
  3. Invest in proactive contingency measures appropriate to specific regional risks
  4. Seek insurance policies that align with regional climate realities and your risks
  5. Build flexibility into planning through infrastructure, scheduling, or contingency protocols
  6. Communicate transparently with stakeholders about climate risks affecting your event
  7. Treat climate risk as a core operating and financial concern, not only a compliance or public relations risk

Climate perils reshaping festival planning

Heat, wildfire smoke, and air quality alerts are emerging as distinct and growing claim categories, and water availability is creating operational and reputational constraints that can render events untenable. The real challenge is not one peril — it is the combination of perils. As climate-related risks become less predictable, standardised planning is no longer sufficient; event organisers need to be flexible and, where possible, introduce locally informed strategies tailored to the risks in each region. 

Temperature extremes create direct festival implications and challenges far beyond simple discomfort. 

  1. Direct festival costs: water provision, cooling infrastructure, and medical staffing during peak heat events
  2. Extreme heat creates healthcare system strain that may trigger authority intervention and public health alerts
  3. Heat-driven contingency costs can exceed budget planning assumptions significantly
  4. Medical staffing trained in heat-illness response is increasingly standard for summer events

Water availability is creating operational and reputational constraints that can render events untenable — not through explicit bans, but through regulatory restrictions, community conservation mandates, and ethical pressures.

  1. Municipal water supply alone can be insufficient during peak summer demand
  2. Water-intensive events face ethical and reputational difficulty during drought periods
  3. These disruptions may not be contemplated by traditional cancellation insurance policies
  4. Organisers are increasingly securing backup water supply through mobile provision systems

Intense rainfall and flooding remain a major concern for festivals and outdoor events, though the timing and operational impact vary by region.

  1. Flood-related disruption is concentrated during hurricane season (June–November, North America) and monsoon season (May–October, Asia)
  2. Many established event venues lack resilience to intense precipitation — poor drainage infrastructure amplifies disruption risk
  3. Infrastructure investment is becoming necessary, not optional: improved drainage systems, elevated infrastructure, and evacuation protocols
  4. Heavy rainfall combined with unpredictable timing creates cascading cancellations across regional event calendars

The real challenge is not one peril — it is the combination of perils.

  1. Heat + wildfire smoke + air quality alerts = cancellation pressure even without direct thermal threat
  2. Intense rainfall + poor drainage infrastructure + unpredictable timing = amplified disruption risk
  3. Heat + water restrictions + medical system strain = authority-level intervention
  4. Drought + wildfire season + heat = sustained public health restrictions
  5. Traditional single-trigger insurance policies do not address compound scenarios as desired

What organisers and insurers are observing

  • Authority guidance without explicit bans: Authorities issue heat alerts, air quality guidance, and health recommendations without explicitly banning events
  • Unplanned contingency costs: Emergency infrastructure investments are incurred regardless of cancellation, often exceeding standard budget assumptions
  • Operational modifications don't constitute full cancellation: Events proceeding with reduced capacity create impaired revenue without triggering cancellation insurance
  • Financial impact is often broader than simple cancellation claims: Rescheduling costs and authority guidance create new financial pressures

The changing frequency and intensity of extreme weather events — heat, precipitation, drought, wildfire, or compound effects — means that event planning must evolve, and that evolution must be regionally specific. Festival organisers who proactively assess climate risks, invest in resilient infrastructure, and secure insurance coverage aligned with their risks will build more resilient  operations and be better positioned to maintain competitive advantage in an increasingly uncertain environment.
