Floods have disrupted global travel in 2026. They have closed roads, stopped trains, and shut down airports. And the trouble rarely ends when the rain does. Mud, broken bridges and unsafe tap water tend to outstay the storm.
Travel risk firm Riskline sent more than 1,300 flood alerts worldwide from January to September 2026. Its new Flooding Informer 2026 shows how rising water can put lives, trips and local services at risk.
That is a grim tally, but it needs care. Each alert is not a separate flood. Nor does the count prove floods are on the rise. Riskline sent 1,605 such alerts in the same nine months of 2025.
The broader threat is clear. The Centre for Research on the Epidemiology of Disasters logged 119 flood disasters in 2025. Storms alone were more common, with 156.
Deadly toll across Asia
Nepal has paid a dreadful price. On 26 August, a suspected glacier collapse near the border with Tibet sent vast floods down mountain valleys.
By 5 October, Nepal’s disaster agency had confirmed 1,455 deaths, while 5,285 people were still missing. Roads and bridges were torn apart. Power and phone links failed. For those caught in remote areas, there was no easy way out.
It is the kind of crisis that makes a delayed flight seem a small concern.
In India, floods hit about 1.2 million people in Assam from June to August, Riskline says. More than 100 died. Thailand was also hit hard. Floods reached Bangkok and 53 of the nation’s 76 provinces, cutting roads and delaying some airport services.
For tour groups and travel agents, the lesson is plain. A route that looks fine on a map may no longer exist on the ground.
Europe’s transport links take a hit
Nor has Europe escaped. Storm Harry struck Sicily in January. Riskline puts the damage at more than US$1 billion. Trains were hit, while flights at Palermo faced cancellations and diversions.
Then came Storm Leonardo in February. More than 11,000 people had to leave their homes in parts of Andalusia, Spain. Córdoba Airport shut from 6 to 13 February and did not resume operations until 14 February.
A closed airport is bad enough. Add a flooded road and a closed rail line, and even the best-laid travel plan starts to look rather hopeful.
In southern Africa, heavy rain and cyclones brought a far worse human toll. The World Health Organisation says floods and storms from mid-December 2025 to February 2026 affected 1.5 million people. More than 300 died, and over 170,000 were displaced, mainly in Mozambique, Madagascar, South Africa and Zambia.
Health risks after the flood
A flood doesn’t end when the water recedes. Wells and taps may be unsafe. Clinics can close. Sewage can mix with fresh water. Abandoned pools can give mosquitoes a place to breed.
The Philippines shows why this matters. Its health department had logged 13,158 cases of leptospirosis by 7 October 2026. That was 48 per cent more than at the same point in 2025. The disease can spread through water contaminated by infected animals’ urine.
Tourists may miss this risk when they see the sun come out.
Riskline’s EMEA analyst Ryan Rogers warns:
“Flooding is not simply a temporary weather disruption. Its consequences can extend far beyond the initial event, affecting transport networks, access to healthcare and essential services for weeks or even months. For travellers and organisations, understanding these wider risks is becoming an essential part of preparedness. Reliable, real-time intelligence can make a critical difference when conditions change rapidly.”
What travel advisers must check
Riskline urges firms and travellers to heed local alerts, plan a safe way out and have backup routes. It also says to keep enough food, clean water, medicine and other key supplies for at least 72 hours.
Travel advisers can act well before a client flies. Check the latest official advice. Ask if the hotel and transfer firm are still open. Have an emergency contact and a plan if a road shuts.
Check travel insurance terms, too. Flood claims may depend on when you bought the policy, when warnings were first issued, and what the cover includes. The fine print makes dull holiday reading, but a flood is an even worse time to start.
Australia’s Smartraveller warns people not to walk, swim or drive through floodwater. Follow local emergency advice, even if it means changing a trip.
For the trade, this is no longer just a bad-weather issue. It tests duty of care, clear advice, and quick decisions.

Octavia Koo arrived in Australia in the early eighties with little fuss and a good eye. Sydney suited her. At UNSW, she studied Arts, then found her footing in graphic design before drifting, quite naturally, into the digital side of things, building websites and shaping words that made people want to stay.
Singapore followed, and with it, the fast pace of tourism platforms and ITB Asia. Long before SEO became a buzzword, Octavia understood how stories travelled online. That’s where she met Stephen, and the seed for something more was planted.
A few years later, she joined Stephen’s EGT Media.
Today, Octavia works with quiet assurance, blending art, instinct and experience to produce stories that don’t shout; they simply work and linger.
