Thailand does not have one durian season, it has several that run one after another as the crop moves across the country. Here is when to expect it, by region and by variety.
In Thailand, durian season runs from about April to August, peaking in May and June. The eastern provinces around Chanthaburi ripen first; the southern provinces come later, stretching fresh Thai durian into September and October.
The eastern provinces around Chanthaburi come first and supply most of the durian you see. As the east winds down, the southern provinces take over, and the deep south near the Malaysian border ripens last. The south runs on a different monsoon clock, and heavy Andaman and Gulf rain pushes flowering and ripening back, so places like Ranong, Yala, and Narathiwat crop months after the east. Every window below is approximate and shifts a few weeks year to year with the weather.
| Region | Season | Peak |
|---|---|---|
| Eastern Thailand (Chanthaburi, Rayong, Trat) | April to August | May to June |
| Central Thailand (Nonthaburi) | April to July | June to July |
| Northeast uplands (Si Sa Ket, Khao Yai) | Late May to August | June to July |
| West (Kanchanaburi, Pa La U) | May to August | June to July |
| Upper south (Chumphon, Surat, Krabi, Phang Nga) | May to August | June to July |
| Deep south (Yala, Pattani, Narathiwat) | July to October | August to September |
Chumphon is the outlier: alongside the main June-to-December run it carries a small early crop in January and February, giving it the longest season in the country.
January to February: The quiet months. Almost no Thai durian, apart from a small early crop in Chumphon in the south.
March: The first eastern durians arrive, led by early varieties like Kradum.
April: The eastern main season opens in Chanthaburi, Rayong, and Trat. Monthong, Chanee, and others come on.
May to June: Peak season. The widest choice and usually the best prices, as the east, central Nonthaburi, and Si Sa Ket all fruit at once.
July: The east winds down. Upland and western areas like Khao Yai and Kanchanaburi, and the upper south, carry on.
August: Mostly southern and late-eastern fruit, as the main eastern season finishes.
September to October: The deep south (Yala, Pattani, Narathiwat) has the last fresh durian of the year.
November to December: Off-season. Little fresh durian except the tail of the Chumphon crop, so most of what you see is frozen or imported.
Supply is highest at the May-to-June peak, which is usually when durian is cheapest. If the price looks steep outside those months, that is part of why durian is so expensive.
The early bird, around March to May. Often the first durian to reach the market each year.
The eastern main season, April to August, and one of the earlier varieties to peak.
The eastern main season, roughly April to August, peaking in May and June.
April to August, but it peaks later than most, around June to August.
The main season runs from about April to August, peaking in May and June. The eastern provinces (Chanthaburi, Rayong, Trat) ripen first, and the southern provinces run later, stretching fresh durian into September and October.
The first eastern durians, like the early Kradum, reach markets around March. The season builds through April and hits full swing in May.
May and June, when the eastern main crop is in full supply. This is usually when common varieties like Monthong and Chanee are easiest to find and best priced.
Not really as fresh fruit. The main run is April to August, the south extends it to around October, and Chumphon carries a long season into December. Outside those months you are mostly looking at frozen durian or imports.
Monthong follows the eastern main season, roughly April to August, peaking in May and June.
The east is mostly finished by August. The deep south (Yala, Pattani, Narathiwat) carries the last of the season into September and October.
The south sits on a different monsoon clock. Heavy Andaman and Gulf rain pushes flowering and ripening back, so southern provinces like Ranong, Yala, and Narathiwat crop months after the eastern provinces around Chanthaburi.
