Heavy seasonal rainfall has triggered widespread flooding across Cambodia this week, forcing more than 2,900 families from their homes and inundating tens of thousands of houses in what national disaster officials describe as one of the more significant flood events of the season.
The Scale of the Flooding
According to Cambodia’s National Committee for Disaster Management (NCDM), the flooding has affected 25,561 families nationwide, with 2,908 families evacuated to safer ground and 24,505 homes reported inundated across 10 provinces. The flooding has also damaged an estimated 12,551 hectares of rice fields, a significant blow to farming communities during the growing season. Cambodian authorities have not named the specific provinces affected in public statements so far, and no deaths or injuries have been reported in connection with this round of flooding.
Not a Mekong Overflow
Officials have been clear that this flooding is driven by heavy localized rainfall rather than the Mekong River breaching its banks. NCDM spokesperson Soth Kim Kolmony confirmed that Mekong water levels remain below alert thresholds. Some of the rainfall has been linked to the peripheral effects of a typhoon system moving through the region. Forecasters expect the wet conditions to continue through September 30, meaning the flood situation in affected areas could still develop further before it improves.
Update, September 29
As of September 28, Cambodia’s National Committee for Disaster Management reports the flooding has escalated sharply: 44,889 families now affected (up from 25,561), 3,685 evacuated, 40,384 homes flooded, and 49,925 hectares of rice fields damaged, still across 10 provinces. Battambang, Banteay Meanchey, and Siem Reap — the gateway province for Angkor Wat — are now named among the worst-hit. In Banteay Meanchey, the border town of Poipet, a common overland entry point from Thailand, was hit hardest, with more than 1,200 families evacuated to nine government shelters. The cause remains local heavy rain plus peripheral effects of a typhoon system, not a Mekong overflow; no deaths have been reported, and rain is forecast to continue through September 30.

Why This Matters for Travelers
Cambodia’s rainy season regularly brings localized flooding to low-lying and rural areas between roughly June and October, and this week’s flooding is a reminder that conditions can escalate quickly in affected regions. While the specific provinces have not been officially named, travelers with plans anywhere in Cambodia over the next several days should build in extra flexibility, since flooding can affect road conditions, rural transport links, and travel times even outside the hardest-hit areas.
What Travelers Should Do
If you have travel planned in Cambodia in the coming days, check road and transport conditions with your hotel, guesthouse, or tour operator before setting out, especially for routes outside Phnom Penh and the main tourist corridors. Keep an eye on updates from the National Committee for Disaster Management and local news for the latest on which areas are affected. Build extra time into overland journeys in case of detours or delays, and avoid driving or wading through flooded roads, since water depth and road conditions underneath can be hard to judge. If you’re unsure whether your destination is affected, a quick check with your accommodation before departure is the simplest way to avoid surprises.
Siem Reap and Battambang: What Visitors Should Know
Siem Reap, the gateway to Angkor Wat, is among the hardest-hit provinces, and local authorities issued warnings to residents and tourists around the Kulen Mountain area on September 22 as water levels rose there. There have been no reports of Angkor Wat or the main temple complex itself closing, but if a Kulen Mountain day trip is on your itinerary, check conditions with your guide or hotel before heading out. In Battambang, the Samlout, Bavel, and Ek Phnom districts have been hit hardest; travelers weighing whether to add a stop there beyond Siem Reap should see our Battambang vs Siem Reap comparison for what the town normally offers, and check current road conditions before committing to the detour. Despite the flooding, Siem Reap’s air links keep expanding — IndiGo is resuming direct Kolkata-Siem Reap flights from October 1, a sign the airport itself is operating normally even as the wider province deals with flooding on the ground. If you want a broader read on safety in the area, our Siem Reap safety guide is worth a look before you go.
