Best Time to Visit: Destination Weather Guides
When to go, when to stay away, and what the rain actually does month by month — weather-first travel guides for 19 destinations, built from long-term climate normals rather than marketing copy.
Most “best time to visit” advice is written around crowds and flight prices. These guides start with the weather instead: monsoon timing, typhoon windows, humidity, sea temperature, and how many days it actually rains. Each guide includes a month-by-month breakdown and a link to live radar for that destination, so you can sanity-check conditions before you book and again while you are there.

Southeast Asia & the Indian Ocean
Monsoon timing rules this region, and it flips depending on which coast you are on. The dry-season windows below are the difference between glassy seas and washed-out afternoons.
- Best time to visit Bali — go May – September. Avoid: Wet season, Nov – Mar.
- Best time to visit Thailand — go November – February. Avoid: Monsoon, May – Oct.
- Best time to visit Phuket — go November – April. Avoid: SW monsoon, May – Oct.
- Best time to visit Bangkok — go November – February. Avoid: Hot Mar–May; monsoon Jun–Oct.
- Best time to visit Singapore — go February – April. Avoid: NE monsoon, Nov – Jan.
- Best time to visit Philippines — go January – April. Avoid: Typhoon season, Jul – Oct.
- Best time to visit Seychelles — go Apr–May & Oct–Nov. Avoid: Windy trade-wind peaks.
East Asia
Autumn is the quiet winner across East Asia: the summer rains have cleared, humidity drops, and typhoon risk falls away.
- Best time to visit Tokyo — go Late Mar–Apr; Oct–Nov. Avoid: Tsuyu rains Jun; typhoons Sep.
- Best time to visit South Korea — go September – November. Avoid: Jangma monsoon, Jul – Aug.
- Best time to visit Hong Kong — go October – December. Avoid: Typhoon season, May – Sep.
South Asia & the Himalaya
In the Himalaya the monsoon does not just bring rain, it removes the view. Post-monsoon autumn delivers the sharpest mountain visibility of the year.
- Best time to visit Nepal — go October – November. Avoid: Monsoon, Jun – Sep.
Europe & the Mediterranean
The Mediterranean shoulder seasons give you swimmable sea without the July–August heat spikes and crowds. Iceland is the outlier, where the “best” season depends entirely on whether you want darkness or daylight.
- Best time to visit Iceland — go Sep–Mar aurora; Jun–Aug sun. Avoid: Depends on your goal.
- Best time to visit Santorini — go May; September – October. Avoid: Peak heat & crowds, Jul – Aug.
- Best time to visit Rhodes — go May, June, September. Avoid: Peak heat & crowds, Jul – Aug.
- Best time to visit Barcelona — go Late May–Jun; Sep–early Oct. Avoid: Peak summer crowds.
- Best time to visit Antalya, Türkiye — go May–Jun; Sep – October. Avoid: Intense Jul – Aug heat.
Middle East
Desert heat, not rain, is the limiting factor here. The comfortable window is the northern-hemisphere winter.
- Best time to visit Dubai — go November – March. Avoid: Extreme heat, Jun – Sep.
The Americas
Two very different climates: a tropical dry/green season split in Costa Rica, and a four-season continental city where both extremes are worth planning around.
- Best time to visit Costa Rica — go December – April. Avoid: Green season rains.
- Best time to visit New York City — go Apr–Jun; mid-Sep–early Nov. Avoid: Jul–Aug heat; winter storms.
How These Windows Are Chosen
Every guide is built from long-term climate normals — typically 30-year averages published by national meteorological agencies — rather than a single year of data or general impressions. That matters because one unusually wet January tells you very little, while three decades of records tell you what to actually expect. Where a destination has a genuine hazard worth planning around, such as typhoon exposure in the Philippines, rip currents in Bali, or altitude sickness in Nepal, the guide covers that too. Climate normals describe the odds, not a guarantee: they tell you which months are least likely to disrupt a trip, not which days will be dry.
Check Conditions Before You Fly
A seasonal guide gets you to the right month. For the right afternoon, use the live tools: the real-time rain map shows where precipitation is falling right now, the 7-day forecast covers the week ahead, and the air quality map matters more than most travellers expect during wildfire and haze season. You can also jump straight to live radar for 3,300+ locations.
Frequently Asked Questions
What does “best time to visit” actually mean here?
It means the months with the most favourable weather odds: lowest rainfall, most comfortable temperature and humidity, and lowest risk of seasonal hazards like typhoons or monsoon flooding. It is a weather judgement, not a pricing or crowd judgement, though the two often overlap.
Is the shoulder season always a good compromise?
Often, but not always. In the Mediterranean, shoulder months like May and September genuinely give you warm, swimmable conditions with fewer crowds. In monsoon climates, the shoulder month is frequently the transition into the wet season, which can mean the worst of both: rising humidity and increasingly unsettled afternoons.
How reliable are these seasonal windows?
They describe long-term averages, so they are a strong guide to probability rather than a forecast. An unusually early monsoon or a late-season typhoon can and does happen. Use the seasonal guide to choose your month, then check the live radar and forecast in the days before you travel.
Which destinations are good year-round?
Very few are genuinely uniform. Singapore has no true dry season, only wetter and less wet stretches. Seychelles is warm all year but has two distinct trade-wind regimes. Even destinations marketed as year-round usually have a clearly better and clearly worse half.
Do these guides cover sea temperature?
Yes, where it is relevant. Coastal and island destinations include monthly sea temperature alongside air temperature and rainfall, since a warm air temperature and a swimmable sea do not always arrive in the same month.
In Conclusion
Picking the right month is the single highest-leverage weather decision in trip planning — far more than any packing choice. Start with the table above to narrow the window, read the destination guide for the detail, then use the live maps as your departure date approaches.
