The easiest window for a Vietnam visa run out of Da Nang is February through May, when Central Vietnam sits in its dry season and land border crossings run close to their fastest. Outside that window, two fixed dates matter more than anything else: the October-November typhoon peak, and the Tet holiday, which falls on February 14-22, 2026.
I’ve been driving visa-run transfers out of Da Nang to the Lao Bao crossing since 2023, and the same three variables wreck people’s plans every year: the weather, the Tet calendar, and how backed up the checkpoint happens to be that particular week.
Vietnam Visa Run Timing at a Glance
| Period | Weather in Central Vietnam | Holiday risk | Border crossing note |
|---|---|---|---|
| Feb 23 - Jul | Dry, warm, calm coastal seas | None major | Fastest, roughly 1-2h at Lao Bao |
| Feb 14-22, 2026 | Dry but transitional | Tet: 9-day national holiday | Up to ~3h; buses sell out |
| Apr 14-16, 2026 | Dry | Khmer New Year (Cambodia) + Lao Pi Mai | Border-town services slow down near Moc Bai, Ha Tien, Lao Bao |
| Apr 30 - May 3, 2026 | Dry | Reunification Day + Labor Day, 4-day weekend | Heavier domestic travel, book buses ahead |
| Aug - Sep | Wet season starts | None major | Normal, but typhoon risk building from Sep |
| Oct - Nov | Peak typhoon season | None major | Highest risk of road/border closures |
When Is the Best Time for a Vietnam Visa Run?
February through May is the calmest stretch to plan a visa run in Central Vietnam. The region is dry, the coastal road toward Lao Bao is clear, and there’s no major national holiday shutting down the checkpoint or filling up the buses. This is also the window I book most often for clients who have flexible dates.
The wider dry season in Central Vietnam actually runs January through July, but the first two weeks of January still carry Tet-run-up traffic, and by August the wet season is already building. Feb-May is the part of that stretch with the fewest variables working against you.
Which Months Have the Highest Typhoon Risk in Da Nang?
October and November carry the highest typhoon and storm risk around Da Nang, with monthly rainfall that can pass 600mm and more than 20 rainy days in a single month. Risk starts climbing already in September, so I treat the whole Sep-Nov stretch as a season to build in a spare day.
A typhoon doesn’t just mean rain on the drive. Roads toward Lao Bao get closed by local authorities ahead of a storm, and sleeper buses cancel departures with almost no notice. I’ve written up the full typhoon-season bus disruption and refund rules separately.
If your current visa is about to expire, a two- or three-day closure can turn into an overstay problem you didn’t plan for. If your trip has to happen in this window, I’d rather you go two or three days before your visa deadline than on the last possible day.
How Does Tet Affect Vietnam Border Crossings in 2026?
Tet 2026 is a nine-day national holiday, February 14-22, with the Lunar New Year itself falling on Tuesday, February 17. Bus tickets on the Da Nang-Lao Bao route sell out well ahead of the holiday, and immigration lines back up across the whole region.
The neighboring China-Vietnam border reported waits of up to six hours during the 2026 Tet rush, and Lao Bao’s normal 1-2 hour clearance can stretch toward its own holiday ceiling of roughly three hours.
There’s a second Tet-season trap that has nothing to do with crowds: your e‑visa has to list the exact entry port you’re using - “Lao Bao,” not a generic Vietnam entry - or immigration can turn you back even with a technically valid visa. It’s one of the most common mistakes I see, and it has nothing to do with the season, but people rush their applications right before Tet and skip that field.
This is where I usually get pulled in during Tet season. I set the correct entry port on the e‑visa application myself so nobody gets turned back at the gate, and I pay the government fee with a card that evisa.gov.vn actually accepts, since a lot of foreign cards get declined at checkout. On my side that’s the paperwork and the ride to the border; on yours it’s just your passport and your travel dates.
Lao Bao vs Moc Bai vs Ha Tien: Which Crossing Is Fastest?
Lao Bao is the only Laos crossing within reach of Da Nang and clears in about 1-2 hours on a normal day, up to roughly 3 hours during holidays. Moc Bai is the busiest Vietnam-Cambodia gate, on the main Ho Chi Minh City-Phnom Penh highway.
Ha Tien-Prek Chak is the quieter alternative into Cambodia, favored by travelers going the scenic way through Kep and Kampot. I’ve covered the full Lao Bao vs Moc Bai vs Ha Tien breakdown with distances and costs separately.
| Crossing | Countries | Typical clearance | Note |
|---|---|---|---|
| Lao Bao - Dansavanh | Vietnam - Laos | 1-2h (up to ~3h on holidays) | Only Laos crossing near Da Nang; Laos side issues visa-on-arrival, not e‑visa |
| Moc Bai - Bavet | Vietnam - Cambodia | No verified wait-time data | Busiest VN-Cambodia gate, main HCMC-Phnom Penh highway |
| Ha Tien - Prek Chak | Vietnam - Cambodia | No verified wait-time data | Quieter option, scenic route via Kep and Kampot |
Cambodia and Laos have their own calendars to plan around too: Cambodia’s Khmer New Year and Laos’s Pi Mai both fall on April 14-16, 2026, and both slow down services in the border towns on either side of Moc Bai, Ha Tien, and Lao Bao.
How Long Does a Vietnam E‑Visa Take in 2026?
A Vietnam e‑visa costs $25 for single entry or $50 for multiple entry, stays valid for 90 days, and the government portal evisa.gov.vn typically processes an application in three to five working days. It’s non-refundable even if declined, and it’s been open to every nationality since 2023.
The processing time is the same in January and in the middle of Tet, but the mistakes that cause a rejection or a resubmission - wrong entry port, a photo that doesn’t meet spec, a name that doesn’t match your passport exactly - take longer to fix when you’re racing a holiday deadline. Apply with a buffer, not on the day you need to travel. For a done-for-you version, see our Da Nang visa run page.
So When Should You Actually Book Your Visa Run?
If your dates are flexible, book anywhere from late February through May, since that’s the calm season with nothing major working against you. Locked into October or November, build in a spare day around the typhoon forecast and confirm your bus is still running the day before. If your trip lands during Tet (Feb 14-22, 2026) or the mid-April Cambodia/Laos new year window, add at least two extra hours at the border and book your transport two weeks ahead.
Most of the visa runs I drive out of Da Nang with BestBus Vietnam fall into exactly one of those three cases, and I set them up the same way regardless of season.
If you’d rather skip the season math altogether, message me on Telegram with your travel dates and I’ll tell you the same day whether it’s a good week to go.
Methodology: Where These Numbers Come From
The e‑visa fee, validity, and processing time come directly from the official portal, evisa.gov.vn, cross-checked against two independent visa agencies. Tet 2026 dates and the full public holiday count are published by Vietnam’s government news outlet. Typhoon-season rainfall and storm-risk figures are drawn from two independent Central Vietnam travel sources describing the same September-November pattern. Border-crossing clearance times for Lao Bao come from two independent sources plus our own transfer logs; Moc Bai and Ha Tien wait times aren’t independently verified anywhere I could find, so I’ve labeled them as such rather than guessing a number. Khmer New Year and Lao Pi Mai dates are confirmed against two independent holiday-calendar sources.
