When is the rainy season
Weather-model data for Dong Van (2015 to 2024) shows rain from May to September: about 215 to 310 mm a month and 23 to 28 days with more than 1 mm. From October it drops to about 120 mm, and December is the driest month at about 60 mm. These are model values, so a rain gauge may read higher.
What changes on the road
Heavy rain makes the mountain roads slippery, cuts visibility and can trigger landslides and flash floods. Landslides on the main road have been reported in several years, mostly after long or heavy rain. Fog can sit on the passes even on dry days, so the same pass can be fine in the afternoon and poor at dawn.
How to check before you ride
Look at the status of the pass you will ride that day, read the reason, then check the official warning for landslides and flash floods at luquetsatlo.nchmf.gov.vn. Ask your guesthouse about the road ahead. Keep one spare day in the plan so that a bad day does not force a risky ride.
If the weather turns on the road
Slow down, turn the lights on and keep your distance. Stop in a village rather than on a bend or under a slope. Do not cross water over the road. Emergency numbers: 112 (general), 113 (police), 114 (fire), 115 (ambulance).
Questions people ask
Can I ride the Loop in the rainy season?
Many people do, but you need slack in the plan. Check each day's status, and be ready to wait or skip a pass on a red day.
How long does it take to clear a landslide?
It varies from hours to days. We do not guess: confirmed road events appear on the pass page with their source and time.
