🗞️ TOP STORIES

Thailand has officially entered the 2026 rainy season, but TMD forecasts significantly less rain than normal and only 1-2 tropical storms this year.

Nation Thailand reported yesterday that the Thai Meteorological Department has formally declared the start of the 2026 rainy season, but the outlook for the coming months is considerably drier than a typical year. TMD forecasts below-normal rainfall across most of the country and only 1-2 tropical storms, compared with the long-term average of 2-3. The monsoon is expected to arrive later and weaker than usual, with some regions not seeing significant rainfall until mid-June or later. The forecast aligns with every warning signal this newsletter has been covering since late April: the Super El Nino that NOAA gives a 62% chance of emerging by August, the 57% cumulative rainfall deficit already recorded from January to mid-April, and the Royal Ploughing Ceremony's cloth prediction for limited rainfall issued just three days ago.

The practical implications are serious. The Royal Irrigation Department confirmed in late April that national reservoir storage was at 62% of capacity, a figure that will only improve if the rainy season delivers enough to refill what has been drawn down. The Agriculture Ministry's Super El Nino contingency plan, released in late April, warned that rice cultivation in many regions could face insufficient water supply if the monsoon underperforms. Fruit orchards in water-scarce areas were already at risk of tree death. The durian sector is sitting on a 2 million tonne surplus it cannot sell, and fertilizer costs remain elevated from the Hormuz crisis. A drier-than-normal rainy season arriving on top of all of this does not create a new crisis. It deepens the one that is already here.

Bottom Line: For Bangkok residents, the immediate effect of a drier rainy season is less flooding risk (welcome news for anyone who commutes through flood-prone areas), but the secondary effects are what matter: higher food prices as agricultural output falls, continued water management pressure, and an extended haze season if El Nino-driven wildfires intensify across the region from July onward. The rainy season has started. Whether it does its job is the question that will define the second half of 2026.

300 police officers raided 32 companies on Koh Pha Ngan on Wednesday in the largest single nominee enforcement operation Thailand has carried out this year.

More than 300 officers descended on Koh Pha Ngan on the morning of May 13, raiding 32 companies suspected of using Thai nationals as nominee shareholders to hold land and operate businesses on behalf of foreign owners. The operation was coordinated across multiple government agencies, with officers simultaneously entering business premises, requesting shareholder documentation and cross-referencing records against the Department of Business Development's database. The raid follows the in-person shareholder verification requirements that took effect on April 1, which require Thai nationals listed as shareholders in companies with foreign participation to appear in person, present identification and sign a sworn statement denying nominee conduct.

The scale of the operation is the story. Previous enforcement actions on Koh Pha Ngan involved targeted investigations of individual businesses: the 15 fruit-packing companies flagged by the DBD, the Ukrainian and Israeli luxury villa developments under investigation, and the discovery of over 100 companies registered to a single address on the island. Wednesday's raid moved from targeted to systematic, covering 32 companies in a single morning with 300 officers. The message to foreign business operators across Thailand's islands is unmistakable: the enforcement framework that was tightening gradually has now shifted to a pace and scale that leaves very little room for operators who have not already restructured. The Foreign Business Act provides for up to three years imprisonment and fines of up to ฿1 million for both the foreigner and the Thai nominee.

Bottom Line: For any expat in the readership who owns, co-owns or is involved in a Thai-registered business, the pattern is now clear. The crackdown started with isolated investigations, moved to the Phuket beachfront demolitions, escalated through the April 1 verification requirements, and has now reached the point where 300 officers can raid 32 businesses on a single island in a single morning. If your business structure involves nominee arrangements, the window to address that is not narrowing. It is closing.

🍷 SPOT OF THE DAY

LUZ takes the idea of a Spanish tapas bar and puts it on the 33rd and 34th floors of a Sukhumvit hotel, and the result is a rooftop that feels more like a neighbourhood in Barcelona than a Bangkok skyline experience. The format is built around chefs and bartenders working side by side behind the same counter, presenting Spanish street food classics, creative signature dishes, Spanish wines, craft gins and innovative cocktails in a way that blurs the line between kitchen and bar in exactly the way tapas culture is supposed to. The views are panoramic across the Bangkok skyline, and the open-air terrace on the 34th floor catches the evening light in a way that makes sunset feel like the first course rather than the backdrop. The food covers the range from ibérico ham and patatas bravas through to more ambitious plated dishes, and the cocktail list leans heavily on gin and citrus, which is the right call for a warm evening 33 floors above the city. Saturday nights have a live, social energy without tipping into the kind of volume that makes conversation impossible. For a Saturday evening on Sukhumvit when you want something that feels European, elevated and unhurried, LUZ is the call.

TIP: Book a terrace table for sunset. The 34th floor fills up from around 6:30PM on Saturdays. The gin-based cocktails are the strongest section of the drinks menu.
