July is summer in northern Vietnam, is the dry season with hot temperatures in the Central Coast, is the rainy season with pleasant or chilly temperatures in the Central Highlands and rainy season with pleasant temperatures in southern Vietnam.
It is worth noting that with global climate change, and Vietnam is a long and skinny country with a long coastline, the weather patterns in Vietnam in a given year may be drastically different from the norm.
And it was dramatically different in 2025 as we found that the dry season in the Central Highlands and southern Vietnam was much less dry than normal. The Central Coast of Vietnam suffered from a typhoon in June with flooded places from Quang Binh, Quang Tri, Hue, Da Nang and Quang Nam Provinces. There was rain all over Vietnam in June 2025. Northern Vietnam seemed to have been experiencing a much shorter summer than normal with very pleasant temperatures mostly and only a short few days with high temperatures above 35oC.
Some bird species in the Central Highlands started nesting and mating from March 2025 which was quite unusual.

Adventure Travel, Nature Tours, Bird Watching Tours, Photo Tours in Vietnam in July
1/ Hiking Tours, Mountain Trekking Tours
July is not a good time time for trekking tours or mountain hiking trips in northern Vietnam and in the Central Highlands of Vietnam. This is because of either hot or rainy weather.
It is often warm or hot and humid in northern Vietnam and this makes it not suitable for long distance hiking. There are occasional rain in the region that the trekking trails are quite muddy or slippery.
In the Central Highlands, it is the rainy season that makes trekking or hiking tours not operable due to either muddy trails or flooded tracks.
2/ Adventure Tours
The lowland of Northern Vietnam including Hanoi, Halong Bay and Ninh Binh is a good place for general adventure holidays in July. It may be humid or it may be short-lived rain in this region, most tours in the region are still operable.
In the Central Coast of Vietnam, it is more likely to be hot in July. But general adventure tours such as walking or country road biking are still fine as this is done mostly in the shade or by the sea with some breezes.
In the Central Highlands, it isdaily short-lived rain. If you plan for adventure tours by car, then your tours should be fine still. The air is fresh and the temperatures are very pleasant mostly.
Southern Vietnam is to experience pleasant temperatures mostly and there is daily short-lived rain. All adventure tours such as walking, cultural exploration, boat trips... are to be done without any difficulties. It is good to know that some streets in Saigon Ho Chi Minh City, in Dong Nai and Binh Duong may be temporarily flooded after each heavy rain which may pose dangers from electricity leakage, open sewers... Some flooded streets in Dong Nai and Binh Duong may have strong currents that could sweep away people and vehicles.
3/ Birding Trips and Bird Watching Tours
July is not a good time for bird watching all over Vietnam: in the North of Vietnam, in the Central Coast, in the Central Highlands and in southern Vietnam. The reason is that it is hot in the North and in the Central Coast, and it is rainy season in the Central Highlands and in southern Vietnam. Most migratory bird species have returned to their resident areas. And most bird species have come into a period of nesting and mating in July.
But for those who can not change your trip to a different time, then it is still possible to observe resident birds in all birding sites in Vietnam. Besides, the rain in the Central Highlands and southern Vietnam in July last 1 or 2 hours per day only, and you can always have the rest of the day for bird watching.
Sites for bird watching in Vietnam in July :
- Cuc Phuong National Park (Ninh Binh): resident birds, some bird species have nesting and mating time in July.
- Van Long Nature Reserve (Ninh Binh): resident and migratory storks and waterfowls.
- Xuan Thuy National Park in Nam Dinh Province : water birds, some migratory species.
- Bach Ma National Park in Thua Thien-Hue Province with representatives of birds between northern and southern Vietnam. It is tricky with the weather at Bach Ma at anytime of the year!
- Yok Don National in Dak Lak Province in the Central Highlands of Vietnam: among the best places in Vietnam for birding, bird watching.
- Da Lat, Bidoup Nui Ba National Park, Deo Nui Sam at Di Linh (Lam Dong, Central Highlands) : among the best places in Vietnam for birding and bird-watching tours, highly rich in endemic bird species.
- Cat Tien National Park (Dong Nai, Southern Vietnam) : July is among the best places in Vietnam for birding and bird watching.
4/ Family Tours
Generally speaking, families should have a great time traveling in Vietnam in July if you only travel in the lowland in the North, in the Central Coast and in southern Vietnam. July is not a good time for family holidays in the far northern mountains because rainy weather may pose dangers such as flash floods, landslides, rockslides.
5/ Island Holidays
July is a great time to make trips to the islands in Vietnam. The reason is the sea is often not rough, and sea exploration tours are operational due to the weather. The temperatures are also perfect on islandsin Vietnam in July. Be warned that there may be typhoons/cyclones,hurricanes in northern Vietnam in July which may disrupt boat trips between the inland and the islands.
Some typhoons are very strong which cause rough sea all over Vietnam during the time of influence, and in this case boat travel (and possibly air travel) between the islands all over Vietnam and the inland are disrupted.
6/ Beach Vacations
July is a good time for beach holidays in Vietnam. But beaches in the country may be crowded due to that the Vietnamese are having summer holidays too.
In Northern Vietnam, Sam Son Beach, Cua Lo Beach or the beaches on islands in Northern Vietnam have pleasant or warm temperatures. The beaches are crowded this month.
And those beaches in the South of the Central Coast have mostly sunny weather, and with pleasant or warm temperatures : Quy Nhon, Tuy Hoa, Ninh Chu, Mui Ne, Phan Thiet.
If you travel to Southern Vietnam then you July try Vung Tau Beach, Long Hai Beach and Ho Tram Beach (all in Ba Ria-Vung Tau Province). You can have pleasant temperatures with some sun and mostly clouds, and some short-lived rain.
