(Bloomberg) --Bad Bunny had a problem. Days before the Puerto Rican mega-star was set to perform in Colombia earlier this year, the possibility of heavy rains threatened to turn three sold-out shows in Medellin into multimillion-dollar losses.
Solutions were few. Traditional event cancellation insurance is rarely available so close to a performance date. Even if a policy could be secured, geography posed another challenge. The nearest official weather sensor sat a mile from the open-air venue — too far, in a tropical city with steep terrain and complex microclimates, to serve as a reliable trigger for a payout.
So a transatlantic team of brokers, underwriters and meteorologists devised a workaround to save Bad Bunny from losses: They installed a temporary weather station inside the stadium, linked to a bespoke policy that would pay out if rainfall exceeded a set threshold.
The ad hoc fix shows how concert, sports and live event organizers are rethinking their approach to nature's unpredictability — and highlights how a specialized corner of the insurance market is evolving to meet that need.
So-called parametric insurance, which doesn't require proof of loss, has
But preparing for a hyper-local weather event in a window of just a few hours — say, heavy rain during Formula 1 races — is uniquely challenging. The short time frame magnifies atmospheric volatility, making it difficult for insurers to accurately price risk. On-site weather stations can help address that, with the caveat that the narrower the window, the more granular the data must be.
"The limiting factor that we have in this business is always data," said Ralph Renner, head of origination at strategic risk advisor Parameter Climate.
While Vaisala Oyj — the Finnish-listed weather intelligence and monitoring firm that installed the equipment — declined to name the performer and most involved were restricted due to legal agreements, one person familiar with the operation confirmed the client was Bad Bunny.
A Stadium Weather Station
To gather data ahead of Bad Bunny's concerts, reinforcements were needed quickly. David Whitehead, who works for Vaisala, flew to Medellin with equipment in tow.
Each day, Whitehead set up two groups of sensors at Atanasio Girardot stadium. One was a military-grade weather station measuring temperature, wind speed and precipitation. The other was a backup rain gauge.
With front-row seats to the performance, which he declined to disclose details about, Whitehead got to work, monitoring the sensors' operation and keeping curious backstage staff from getting too close.
"Redundancy is key," he said. "We really can't fail. I can't find out later that something wasn't recording or was erroneous."
Because the promoter's primary concern was a storm severe enough to cancel the shows, the insurance policy was structured to trigger if rainfall exceeded a certain threshold before or during each concert, said Edoardo Ferri, a senior underwriter at Paris-based Descartes Underwriting SAS, which backed the coverage. Payouts increased with the amount of precipitation, up to a defined limit.
Although rainfall alone determined whether the policy paid out, installing a full weather station added what Whitehead called "statistical security." By capturing a range of atmospheric variables, the system made it far harder to manipulate readings — for example, by aiming a sprinkler at the sensor — since a spike in rainfall without corresponding changes in factors like solar radiation and humidity would stand out as suspicious.
Descartes declined to disclose the coverage amount for the Colombia concerts but said it can provide as much as $80 million per contract for a range of weather risks. Some 145,500 tickets were sold across the three shows, generating $23.7 million, according to Pollstar — before factoring in food and beverage sales, which also would have suffered in a washout.
Bad Bunny's management team didn't respond to requests for comment.
Bad Bunny, Meet Basis Risk
For Vaisala and Descartes, the temporary weather station was a novel fix for what insurers call "basis risk" — the chance that rain falls at the venue but isn't recorded at an official weather station used to settle the contract. Putting the station inside the stadium solved that problem.
"If we couldn't have the on-site weather station, I'm not sure we'd even write the policy," said Myles Roberts-Bailey, a business developer at Descartes.
In that context, the Colombia concert was a successful test run for both companies, which see more untapped demand for bespoke parametric insurance paired with on-site weather monitoring.
Industry players say the approach could spread to other outdoor events. Even a decade ago, providing a similar service would have required a four-person team hauling a much bulkier weather station packed into 10 suitcases, Whitehead said. Technological advances have shrunk sensors and streamlined the field work. Now it's enough to send one person and a weather sensor "the size of a shoe box."
"It makes it a lot more cost-effective and feasible," Whitehead said.
Better data is also improving how risks are priced. Higher-quality, on-site measurements help underwriters reduce uncertainty, which can lower costs for clients, said Paul Jones, head of parametrics for the UK and Europe at insurance broker Lockton, which helped broker the Colombia concerts' coverage.
Rising demand for live events in the post-pandemic era, coinciding with increasingly volatile weather, means greater potential for parametrics to play a role.
In the end, Bad Bunny's Medellin concerts went off without weather interruptions.
Three days later, heavy rains
