Cool & Dry Season (November–February): Ideal for Multi-Country Exploration

• Vietnam: Clear skies in the north (Hanoi, Ha Long Bay: 15–25°C) and central regions (Hoi An, Hue: 20–28°C); cooler evenings perfect for street food tours.

• Cambodia: Peak season for Angkor Wat (Siem Reap: 20–30°C); low humidity, ideal for sunrise photography and temple hopping.

• Thailand: Coolest months nationwide (Bangkok: 20–30°C; Chiang Mai: 15–28°C); perfect for island-hopping in Phuket or Koh Samui.

• Why Visit Now? Comfortable weather for outdoor activities, fewer crowds at major sites early in the season, and vibrant pre-Tet energy in Vietnam.

• Legend Travel Group Tip: Combine Vietnam Tours in the north with Cambodia Tours in Siem Reap and Thailand Tours in Bangkok for a 12-day dry-season highlights itinerary.

Hot Season (March–May): Adventure & Festivals

• Vietnam: Warming up (Hanoi: 25–35°C); central beaches (Da Nang) at their best; pre-monsoon heat builds energy for Khmer New Year.

• Cambodia: Hottest month in April (Siem Reap: 28–38°C); Khmer New Year (mid-April) brings water fights and temple ceremonies.

• Thailand: Peak heat (Bangkok: 30–38°C); Songkran (April 13–15) transforms streets into joyous water battles.

• Why Visit Now? Experience Southeast Asia’s biggest festivals; fewer tourists mid-week; excellent visibility for diving in Thailand’s islands.

• Legend Travel Group Tip: Join a Cambodia Tours festival package during Khmer New Year, then cool off with Thailand Tours on Koh Phi Phi.

Wet Season (June–October): Lush Landscapes & Fewer Crowds

• Vietnam: Monsoon in the north (Hanoi: 25–33°C) and south (Ho Chi Minh City: 25–32°C); central region driest July–August.

• Cambodia: Heavy but short afternoon rains (Siem Reap: 25–32°C); Angkor Wat surrounded by lush greenery and reflective moats.

• Thailand: Southwest monsoon (Phuket: 25–32°C); east coast islands (Koh Samui) sunny July–September.

• Why Visit Now? Lower prices, dramatic cloudscapes for photography, rice paddies at their greenest, and intimate cultural experiences.

• Legend Travel Group Tip: Opt for Vietnam Tours in central Vietnam (Hoi An, Hue) during July–August, paired with Thailand Tours on Koh Samui’s sunny side.

Respecting Local Traditions in Three Kingdoms

Cultural harmony is key when traveling across Vietnam, Cambodia, and Thailand. Legend Travel Group ensures every Vietnam Tours, Cambodia Tours, and Thailand Tours itinerary includes respectful practices:
