Chonburi flooding triggers evacuations and marine disruption

More than 200 households were evacuated in Nong Kham

Heavy rain caused serious flooding in parts of Si Racha district on September 25. In Nong Kham, water approached one metre in some locations, prompting the district chief to order the evacuation of more than 200 households. Wat Nong Kham was used as temporary shelter, with local teams giving priority to older residents and people who needed assistance leaving their homes.

Flooding also affected road access. Several routes in Si Racha became difficult or unsafe for small cars and motorcycles, and local officials warned drivers away from deeper sections where vehicles could stall or be exposed to stronger currents.

The disruption was highly localised. Conditions in Nong Kham did not describe the whole of Chonburi, and even neighbouring roads could have very different water levels. For residents and commuters, the useful question was therefore not simply whether “Chonburi was flooded”, but whether the specific route they needed was passable.

Rough seas disrupted Pattaya departures and the Koh Si Chang ferry

The same weather system also affected marine travel. Ferry service between Koh Loi pier in Si Racha and Koh Si Chang was temporarily suspended on September 25 as strong winds and rough seas made the crossing unsafe. In Pattaya, marine authorities raised red flags and stopped boats from leaving shore during the dangerous conditions.

These were separate operational decisions affecting specific areas and services. They should not be read as evidence that every port or ferry route in Chonburi was closed. For people living on Koh Si Chang, commuting along the coast or planning a day trip by sea, the practical consequence was that a normal timetable could no longer be assumed while the weather remained unstable.

The weather warning continued through September 27

A Thai Meteorological Department advisory issued on September 26 forecast waves of roughly two to three metres in the upper Gulf, with higher seas in thunderstorms, through September 27. Small boats were advised to remain ashore, while heavy to very heavy rain remained a concern for parts of eastern Thailand.

That broader weather warning is not the same thing as an extension of every local evacuation or harbour order from September 25. In the sources checked for this article, there was no sufficiently reliable confirmation that the original Nong Kham evacuation order or Pattaya’s blanket departure ban remained unchanged on September 27. Anyone travelling through previously flooded roads or relying on a ferry should therefore check the current status of that exact route or pier rather than rely on the September 25 notice alone.
