The figure is significantly higher than Phuket’s long-term annual average of 2,195.3mm, confirming what officials describe as an unusually wet year. It has also exceeded the total rainfall recorded in 2024, which stood at 2,396.2mm.
According to the TMD’s monthly breakdown, October and November this year saw particularly heavy rainfall.
October delivered 508.2mm, far above the 30-year monthly average of 336mm. Last year, the island recorded 320.1mm in October.
This month, Phuket has already recorded 191.9mm in just the first 19 days, surpassing the historical monthly norm of 174.8mm and well above the 54.3mm logged in November last year.
Several earlier months also recorded substantial increases.
May marked the start of the monsoon, with 492mm of rain ‒ more than double the long-term average of 236.9mm. Last year May saw only 203.1mm.
June registered 402.8mm, well above the long-term average of 249.4mm and the 203.1mm recorded last year.
The mid-rainy season proved comparatively dry. July recorded just 127.4mm, below the 30-year average of 240.1mm and below last year’s unusually wet July, which saw 344mm.
August this year saw 293.8mm of rainfall, compared with the 30-year average of 308.6mm and last year’s 424.4mm, while September this year logged 237.7mm, compared with the long-term average of 349.7mm and the exceptionally heavy 644.4mm last year, which triggered landslides across the island, including the deadly landslide in Kata.
With more than a month still to go before year-end, officials say Phuket’s total rainfall for 2025 is likely to exceed 2,700mm, marking one of the wettest years in recent records.
