- Highest temperature: 28-31 degrees C, in some places above 31 degrees C.
Cloudy, scattered showers and thunderstorms in some places in the morning, then light rain in some places. Light wind.

Advice for tourists:
1. Proactively schedule
Visitors should prioritize sightseeing and outdoor travel in the morning and early afternoon. Limit planning activities that last until late afternoon when the risk of thunderstorms increases.
2. Bring a raincoat
A lightweight raincoat or umbrella is a necessary item when exploring the Northwest in this weather. Showers can appear quite quickly, disrupting the schedule.
3. Be careful when traveling
If traveling by motorbike, tourists should slow down when it rains, especially on mountainous, steep and winding roads. Slippery road surfaces can increase the risk of unsafety.
4. Do not try to move when stormy
When thunderstorms appear, tourists should temporarily stop their journey and find safe shelter. Do not try to continue moving outdoors during this time.
5. Avoid large tree areas
During thunderstorms, it is necessary to limit standing under tall trees, near power poles or temporary structures. Tornadoes and strong gusts of wind can be dangerous for visitors.
6. Check forecasts before leaving
Mountain weather can change rapidly between regions. Visitors should check forecasts before each route and flexibly adjust their itinerary if thunderstorm warnings appear.
