The situation as of 8 October 2026
Severe flooding continues to affect 27 provinces and Bangkok, with the Department of Disaster Prevention and Mitigation (DDPM) reporting 1,149,285 households still impacted as of 8 October 2026, per the Chiang Rai Times. An earlier DDPM count on 4 October recorded 1,171,165 affected households representing over 3.26 million people, per The Nation Thailand.
Chon Buri province, which includes Pattaya and the surrounding area, is named explicitly in the Bangkok Post’s province list as of 3 October 2026. That makes this a live local issue, not a distant national headline.
What has already happened in Pattaya and Chonburi
On the night of 23–24 September 2026, more than an hour of thunderstorms caused widespread flooding across Pattaya in Bang Lamung district, with water rising rapidly on several roads and reaching around 50 centimetres in many locations and as much as one metre in some of the city’s recurring flood-prone areas, per The Nation Thailand. Highway 331 in Si Racha was also submerged, with floodwater covering all traffic lanes towards Laem Chabang and traffic backed up for several kilometres by early morning.
As of 5 October 2026, Chonburi’s reservoirs were reported above their normal storage threshold, with irrigation officials ordering faster drainage ahead of further expected rain, per The Pattaya News. Residents in Phan Thong and Phanat Nikhom were specifically advised to watch natural waterways for rising levels and to prepare early.
What is still coming
Thailand’s Joint Information and Coordination Center (JICC) issued a rain-bomb alert for Pattaya and Chonburi on 5 October 2026, per Khaosod English. A further period of heavy rain was forecast for 10–13 October, with water from northern rivers expected to continue flowing into the Central Plains. Southern provinces were also warned of increased rainfall and flash-flood risk during this period.
While water levels are declining in the North and Northeast, they continue to rise in several Central provinces receiving large volumes of upstream water, per The Nation Thailand.
What this means for daily life in Pattaya
For residents and retirees living in or around Pattaya, the practical effects are real and ongoing:
- Roads. Flood-prone roads in Bang Lamung district and along Highway 331 towards Si Racha and Laem Chabang have already been impassable for smaller vehicles. If you drive a low-clearance car or a motorcycle, check conditions before setting out, particularly after overnight rain.
- Drainage. Chonburi’s canal and drainage infrastructure is under active management. Officials are pumping and dredging around Phan Thong and Phanat Nikhom. If you live near a canal or in a low-lying area of Pattaya, keep an eye on water levels at your property boundary.
- Reservoirs. Khlong Luang Ratchalothorn Reservoir releases are being managed in stages. Downstream communities have been warned. If you are in a downstream area, follow local authority announcements.
- Further rain. The 10–13 October window carries a real risk of additional accumulation on already-saturated ground. This is not a situation that is over.
What to do this week
- Follow the DDPM. The Department of Disaster Prevention and Mitigation publishes daily situation reports. Their figures are the primary source for province-level flood status.
- Follow the Thai Meteorological Department. Daily forecasts are published at tmd.go.th and are the authoritative source for rainfall warnings.
- Check local Pattaya groups. Real-time road conditions circulate faster on local Facebook groups than on any official channel. The Pattaya News also publishes same-day flood updates.
- Move valuables upstairs if you are in a ground-floor unit in a flood-prone area. This is a practical step, not an overreaction, given that water rose to one metre in some Pattaya locations in late September.
- Keep a torch and a power bank charged. Short outages follow heavy flooding in some areas.
What is still unknown
The situation is evolving daily. As of 8 October 2026:
- It is not yet confirmed whether the 27-province count will rise or fall in the coming days.
- The full damage assessment for Chon Buri province has not been published.
- Whether the 10–13 October rainfall period will bring a further surge to Pattaya-area roads and canals is not yet known.
- Long-term infrastructure repair timelines for Highway 331 and Bang Lamung district roads have not been announced.
