Best Time to Visit Southeast Asia & Japan
The dry windows, the shoulder months worth gambling on, and the monsoons that quietly ruin an itinerary — eight countries, one table.
Last updated: June 2026.
Asia does not have one climate; it has dozens, stacked on top of each other and running on different calendars. The same week that delivers cool, cloudless mornings in Hanoi can be drowning the Mekong Delta a few hundred miles south. Bali and Bangkok dry out as Tokyo turns humid; the Andaman and the Gulf of Thailand sit on opposite coasts of the same country and rain in different months. The single most useful thing you can do when planning a long trip is to sequence countries — and regions within them — by the weather, then let the itinerary fall into place around that. What follows is the reckoning, learned mostly by arriving in the wrong place at the wrong time. For the mechanics of stitching those windows together, see Itinerary Building.
When is the best time to visit each country?
Broadly, the November–to–February cool-dry season suits mainland Southeast Asia — Thailand, Vietnam’s north, Cambodia — while Indonesia and the Philippines run on a roughly opposite April–October dry calendar in part. Japan’s two glories are spring blossom and autumn foliage. The table below is the quick reference; the country notes beneath it add the regional detail that the table flattens.
| Country | Best months | Shoulder | Avoid / wettest | Notes |
|---|---|---|---|---|
| Thailand | Nov–Feb (cool, dry) | Mar–May (hot) | Jun–Oct (wet) | Andaman coast wettest May–Oct; Gulf & Koh Samui wettest Oct–Dec. |
| Japan | Late Mar–Apr (blossom); Oct–Nov (foliage) | May; Dec–Mar (ski) | Jun (tsuyu rains); Jul–Aug (hot, humid); Aug–Sep (typhoons) | See the cherry blossom guide for 2026 bloom dates. |
| Vietnam | North Oct–Apr; Centre Feb–Aug; South Dec–Apr | Varies by region | Centre Sep–Dec (floods); South May–Nov | A 1,000-mile country with three climates — never one answer. |
| Indonesia | Apr–Oct (dry) | Apr & Oct (edges) | Nov–Mar (wet) | Bali follows the same pattern; July–August is peak and busy. |
| Philippines | Dec–Apr (driest) | Nov & May | Jun–Oct (wet, typhoons; peak Jul–Oct) | Dry season runs Nov–May overall; typhoons can still graze in shoulder weeks. |
| Cambodia | Nov–Feb (cool, dry) | Mar–May (hot) | Jun–Oct (wet) | The wet season greens Angkor and fills the moats — not without its case. |
| Malaysia | West coast Dec–Apr; East islands Mar–Oct | Borneo: year-round | East coast Nov–Feb (monsoon) | The two coasts rain in opposite halves of the year. |
| Taiwan | Spring; Oct–Nov (autumn) | Mild southern winters | May–Jun (plum rains); Jul–Sep (typhoons) | The south stays warm and drier when the north turns grey. |
When is the best time to visit Thailand?
The best time to visit Thailand is the cool-dry season from November to February — comfortable temperatures, low humidity, blue skies over Bangkok and the islands. March to May is fierce, dry heat; June to October is the wet southwest monsoon. Note the split coasts: the Andaman (Phuket, Krabi) is wettest May–October, while the Gulf and Koh Samui rain hardest October–December.
That coastal asymmetry is the planning trap. If your dates are fixed in, say, June, the Gulf islands are often the smarter bet than Phuket; flip it in November and the Andaman wins. More on sequencing the beaches in the Thailand destinations pages.
When is the best time to visit Japan?
Japan is at its finest in two short windows: cherry blossom from late March into April, and autumn foliage through October and November, when the maples turn and the air is crisp and dry. Avoid the tsuyu rains of June, the heavy heat and humidity of July–August, and the typhoon risk of August–September. Winter brings world-class snow to Hokkaido and the Japan Alps.
Blossom is the headline draw and the hardest to time — the front moves north over roughly two weeks and the peak lasts only days. We’ve given it a guide of its own: Japan Cherry Blossom 2026, with city-by-city dates and viewing spots. For the destinations themselves, start with Tokyo, Kyoto, and Mount Fuji & Hakone.
When is the best time to visit Vietnam?
Vietnam has no single best season because it spans three. The north (Hanoi, Sa Pa) is cool and dry October–April. The centre (Hoi An, Da Nang, Quy Nhon) is dry February–August and floods September–December. The south (HCMC, the Mekong) is dry December–April, wet May–November.
The sweet spot for a full north-to-south sweep is February to April, when all three regions are broadly dry at once. Travel in the autumn and you must choose: the north is glorious while the central coast is taking on water. Plan the route around that fork, not against it.
When is the best time to visit Indonesia and Bali?
The best time to visit Indonesia and Bali is the dry season from April to October, when the rice terraces are green, the dive visibility is good, and the afternoons stay clear. November to March is the wet season — warm but humid, with heavy tropical downpours, especially January and February. July and August are the driest and busiest months; the shoulders of April, May, and October trade a little rain for far fewer crowds.
When is the best time to visit the Philippines?
The dry season in the Philippines runs November to May, with December to April the best stretch for island-hopping — calm seas, reliable sun, the full archipelago open. The wet, typhoon-prone season is June to October, peaking July–October. The country sits squarely in the Pacific typhoon belt, so even good months can be brushed by a passing storm; build slack into ferry and island legs.
When is the best time to visit Cambodia?
Cambodia is best in the cool-dry season from November to February — manageable temperatures for tramping around Angkor Wat and clear, dust-free light at dawn. March to May is punishingly hot; June to October is the wet season. The rains aren’t all loss, though: they refill the temple moats, green the surrounding jungle, and thin the crowds at the famous sunrise.
When is the best time to visit Malaysia?
Malaysia splits by coast. The west coast (Kuala Lumpur, Penang, Langkawi) is driest December–April. The east-coast islands (Perhentian, Tioman, Redang) are at their best March–October and largely shut down under the northeast monsoon November–February. Borneo — Sabah and Sarawak — is reliably warm and wet enough to visit year-round, with no true off-season.
When is the best time to visit Taiwan?
The best times to visit Taiwan are spring and autumn, with October and November especially reliable — warm, settled, and clear. Avoid the plum rains (meiyu) of May and June, when the island sits under weeks of drizzle, and the typhoon season of July to September. Southern Taiwan (Kaohsiung, Kenting) stays mild and comparatively dry through winter when Taipei turns cool and grey.
How should I sequence a multi-country trip?
The simplest rule: chase the dry seasons rather than fight them. A November–to–April overland arc through Thailand, Cambodia, southern Vietnam, and Malaysia’s west coast keeps you in the dry almost the whole way, then hands you off to Japan’s cherry blossom at the very end of the window. Pivot the same trip into the northern summer and you’re suddenly dodging three separate monsoons. Read the weather first, draw the line second.
