Residents are urged to check risk areas, as this morning’s sea level spike set a new annual record at Bang Pu, with water reaching 1.99 metres, 18 centimetres higher than yesterday. Flooding has now impacted all routes surrounding Pak Nam – Phra Samut Chedi, with close monitoring required for areas outside flood barriers or where flood protection infrastructure remains incomplete.

Tidal surge inundates key areas of Samut Prakan

This morning, several economic and densely populated communities in Samut Prakan were hit by sudden flooding as sea levels surged to their highest point of the year.

On December 6, 2025, Sansern Ruangrit, Assistant Director of Ratchathewi District Office, Bangkok Metropolitan Administration, confirmed the highest tidal level of the year at Bang Pu — 1.99 metres above mean sea level.

He added that while water runoff from upstream has decreased, vulnerable communities located outside flood barriers or near incomplete structures must remain on high alert.
