The short answer
Best overall window: late February to April. All three regions are dry. Tet (Vietnamese New Year) falls in this window — plan around it (everything closes for 5–7 days).
Northern Vietnam (Hanoi, Sapa, Halong Bay)
- Best: October–December (cool dry), March–April (warm dry)
- Worst: July–August (hot + humid + heavy rain)
- Sapa hill towns: Sept–Nov for rice terraces; Mar–May for new green
- Halong Bay: Oct–Nov calmest seas; avoid Jul–Aug typhoons
Central Vietnam (Hoi An, Da Nang, Hue)
- Best: February–April (dry season)
- Worst: September–November (worst monsoons + flooding in Hoi An)
- Beach (Da Nang, An Bang): April–August for warmest water; July–Aug crowded
Southern Vietnam (Saigon, Mekong Delta, Phu Quoc)
- Best: December–April (dry season)
- Worst: May–November (rainy season — afternoon storms, but not all-day)
- Phu Quoc beach: November–April
Tet (Vietnamese New Year) — plan around
Tet 2026: February 17. The week before and after, everything closes. Trains and flights book up. Hotels in tourist destinations stay open but locals all return home — domestic travel is expensive and chaotic. Either come well before (Jan) or 1+ week after (late Feb).
Festivals worth planning for
- Hue Festival: April–May, biennial (2026)
- Mid-Autumn Festival: September — lanterns in Hoi An
- Lunar New Year (Tet): Feb 17, 2026 — see warning above

Practical tips that make the difference
- Plan in advance: book major attractions + restaurants 4-8 weeks ahead in peak season
- Use the local apps: country-specific transport, payment, and food delivery apps work better than generic international ones
- Carry small cash: card acceptance varies; €20-50 in local currency saves moments
- Travel insurance: even a $50 policy saves you from $5,000+ medical bills
- Photograph everything important: passport, BRP, important addresses, emergency numbers
Common mistakes to avoid
- Booking too tight: build 30-50% buffer between commitments. Strikes, weather, jet lag all cause delays
- Skipping local etiquette: brief research on greetings, tipping, and dress codes saves embarrassment
- Eating at tourist-trap restaurants near monuments: walk 2-5 minutes off main squares for better food + better prices
- Underestimating walking: most European + Asian cities are walked, not driven. Comfortable shoes essential
- Ignoring transit cards: city travel cards (Oyster, Suica, Navigo, etc.) are 30-50% cheaper than single tickets
When to consider professional help
For more complex situations — multi-country tax planning, complicated visa applications, or substantial property purchases — engaging a regulated professional saves money and stress in the long term. Look for: OISC-registered immigration advisers (UK), Spanish gestores (Spain), German Steuerberater (Germany), or cross-border tax specialists (any country).
