Samut Prakan is severely affected by "high tide" flooding since the morning of 6 Dec, inundating many areas. Suksawat Road is flooded along its entire length. Vendors express frustration as this problem occurs every year. Despite hurriedly moving goods to higher ground, water levels nearly match those of the 2011 flood, which occurred in 2011.
At 10:30 a.m. on 6 Dec 2025 GMT+7, reporters observed that water levels in the Chao Phraya River rose rapidly due to the high tide, causing water to overflow and flood houses along the riverbanks in several spots. Particularly affected were low-lying areas in Phra Pradaeng and Phra Samut Chedi districts of Samut Prakan province. Water levels reached 60–80 centimeters at times within Phra Pradaeng Municipality. Residents and shop owners rushed to move their belongings to higher ground to prevent damage, but many could not move their goods in time and had to endure the flooding.
Some residents reported that water levels began rising in the early dawn and continued to increase rapidly, flooding the market area within minutes. This caused damage to some of the goods they had prepared for sale. Meanwhile, Phra Pradaeng Municipality urgently placed sandbags to prevent further flooding within the municipal area.
Along the outbound lanes of Suksawat Road heading toward the Phra Samut Chedi intersection—a four-lane road with a median—from the air-conditioned bus depot (Bus No. 138) near Lat Luang Municipality to the entrance of Suksawat Soi 53, all four lanes were flooded over a distance exceeding 5 kilometers. Traffic moved slowly. Rescue vehicles and fire trucks from Lat Luang Municipality, along with officials, assisted in managing traffic, advising drivers to proceed cautiously and keep to the far-right lane where water levels were lower. Some small cars and motorcycles stalled and could not pass through.
Officials had to assist by pushing stalled vehicles to higher ground. On Suksawat Road near Pom Prachula, seawater flooding extended over more than 4 kilometers from the entrance of Wat Laem Fa Pha Soi to the Phra Samut Chedi intersection, with water depths ranging from 40 to 60 centimeters.
Mrs. Phayao Buacharoen, 62, a street food and noodle vendor operating on the sidewalk of Suksawat Road opposite a private school, told reporters she has been selling food here for many years and faces high tide flooding problems every year, especially around the New Year festival. During the 2011 flood that affected Bangkok and its vicinity, her home was also impacted.
Today’s high tide is nearly as high as the 2011 flood, and her household belongings are already submerged. She was unable to secure her possessions in time and had to let them be flooded. Yesterday’s tide was lower than this morning’s. Early this morning, she invested nearly 2,000 baht in goods to sell, which were all ruined by the flood, preventing customers from dining at her stall. She expected the water to recede by about 1 p.m., when she planned to pack up and go home. She does not yet know if the flooding will continue tomorrow and intends to keep her stall closed until the tide subsides.
Regarding the high tide situation, the Hydrographic Department of the Royal Thai Navy reported that high tide flooding will continue for another two to three days before returning to normal conditions. They urged residents living along the Chao Phraya River to remain vigilant about the high tide phenomenon. Assistance with moving belongings or installing water barriers is available from nearby agencies around the clock.
Meanwhile, the Bangkok Metropolitan Administration’s Facebook page has warned residents to monitor Chao Phraya River water levels due to high tides from today through 12 Dec 2025 GMT+7 between approximately 8 a.m. and 2 p.m., especially for 11 communities located outside the flood protection embankments, which are advised to stay alert.
Data from the Drainage and Sewerage Department indicates that Bangkok has 11 communities outside the flood protection embankments along the Chao Phraya River, Bangkok Noi Canal, and Mahasawat Canal, covering six districts: Dusit, Phra Nakhon, Bang Kho Laem, Yan Nawa, Bangkok Noi, and Khlong San. These areas include 320 households with around 1,070 residents living on low riverbanks who are directly vulnerable if water levels rise.
Houses outside the flood protection embankments are located beyond the riverside dikes and are directly affected by the river’s water level fluctuations. Residents in these areas are urged to closely monitor the situation.
