Although it can be wet from March to May, this is still a good time to visit Bhutan as the wildflowers are out in bloom.
September to November is also a great time to visit as rainfall is lower and views are clear.
Although it rains all year round, monsoonal weather can be expected in Bhutan between June and August.
From December to February snowfalls may result in road closures and delays. Nevertheless, winter can be a good time to visit as the days are generally sunny (although cold) and the blanket of snow makes for picturesque panoramas.
Any time of the year is a good time to travel in Cambodia, although there are two distinct seasons – dry (October to late April) and wet (May to late September). In general, the entire country is subject to the same weather patterns, mainly due to the relatively uniform altitude and latitude throughout Cambodia.
The climate in Cambodia is generally hot and humid throughout the year. Temperatures stay in the 30’s most of the year, dropping back to the 20’s at night. The final few dry months leading up to the wet season (March and April) and the early months of the wet season (May and June) are usually the hottest of the year with temperatures in excess of 35°C at times.
Humidity is at its height during March and April whilst the coolest months of the year tend to between October and December, however this is cool for Cambodia but far from chilly (avg temperatures 24°C – 26°C).
The weather in India varies dramatically. While the southern tip of the India is being lashed by tropical monsoon rain, the north will be blanketed in thick snow. Therefore, the best time to travel to India depends greatly on the destinations to be visited and the climate experienced there.
Based on temperature and rainfall, the Indian Meteorological Service has classified the country into seven different climatic regions. These are the Himalayas, Assam and West Bengal, the Indo-Gangetic Plain / North Indian Plain (a huge section of north-central India), the Western Ghats and coast, the Deccan Plateau (south-central India), and the Eastern Ghats and coast. In general, the north of India is cooler, the center is hot and dry, and the south has a tropical climate.
Indian weather itself is divided into three distinct seasons — winter, summer, and the monsoon. Generally, the best time to visit India is during the winter, when the weather in most places is relatively cool and pleasant.
Summer (March to May): India starts heating up from around February, first in the northern plains and then the rest of the country. By April, many places are experience daily temperatures exceeding 40 degrees Celsius (105 degrees Fahrenheit). It stays cooler in the southern parts of the country, with temperatures reaching around 35 degrees Celsius (95 degrees Fahrenheit), although it’s a lot more humid. In late May, signs of the approaching monsoon start appearing. Humidity levels build, and there are thunderstorms and dust storms. The most tiring thing about summer in India is that the heat is so relentless. Day after day the weather doesn’t change — it’s always extremely hot, sunny, and dry. While the summer can be very uncomfortable and draining in most parts of India, it’s the perfect time for visiting the mountains and hill stations. The air there is fresh and soothing. The summer is also the best time to visit India’s national parks as the animals all come out of the thickets in search for water in the heat.
Monsoon (June to October): India actually has two monsoons –- the southwest monsoon and the northeast monsoon. The southwest monsoon, which is the main monsoon, comes in from the sea and starts making its way up India’s west coast in early June. By mid July, most of the country is covered in rain. This gradually starts clearing from most places in northwest India by October.
March, April and May are excellent months to visit Japan and, consequently, are also the busiest. Since it’s springtime, the weather is usually fine and beautiful cherry blossoms are in full bloom.
September, October and November are also great months to visit Japan on holidays, as the days are warm, but not too humid, and the autumn colours make the gardens and countryside look amazing.
Winter offers great conditions for skiing, snowboarding, going to snow festivals and admiring the stunning mountain scenery. The summer months can be quite humid but tourist areas are generally quieter and there are many fun festivals and fireworks displays to enjoy.
You can travel in Laos all-year-round as Laos’s weather system is relatively straight-forward. It consists of a dry season (October to late April) and a wet season (May to late September). The dry months leading up to the wet season (March and April) and the early wet season (May and June) are the hottest of the year.
The early months of the wet season (May – July) remain very hot and rainfall is often short lived, while in the latter months (late July – September) the rains tend to be more constant and can be heavy at times. Throughout much of the rainy season, daytime temperatures average around 29°C in the lowlands and 23°C in the mountain valleys.
Although Burma has two distinct seasons – dry and wet – you can visit the country throughout the year. That being said, at the peak of the wet season some regions become inaccessible and some, such as Ngapali Beach, close altogether in preparation for the high winds and heavy rainfall that batter the coast annually.
Myanmar’s dry season runs from October through to May and the wet season from May/June through to early October. The dry months leading up to the wet season (March and April) and the early wet season (May and June) are usually the hottest of the year when temperatures can reach astronomical highs. The colder months follow the end of the rains, from October to December/January, when it is cool in the foothills and highland areas, especially at night.
The very best months to visit Burma are from November to February however this is also the busiest time.
From June until August the monsoon hits, making it too wet and humid for trekking.
The post-monsoon period from September to November is rice-harvesting season and is characterised by lush vegetation, clean air and excellent mountain views. Days are warm and sunny, although nights become increasingly cool. This is the start of the trekking season, which runs until May.
Winter (December to February) is dry and clear with temperatures dropping below freezing at high altitudes, although in Kathmandu, it can still sometimes reach a pleasant 25 C.
Spring (March to May) is warmer and is a particularly beautiful time to visit as the rhododendrons and the orchids are in flower.
Unlike many other Asian destinations, Sri Lanka can lay genuine claim to being a year-round holiday destination.
The south-western monsoon brings rain to the south-west of Sri Lanka between May and September, while the dry season in this region runs from December to March. In the north and eastern coastal regions of the country, the weather is influenced by the north-eastern monsoon, which brings wind and rain between October and January, and dryer weather between May and September. There is also an inter-monsoonal period during October and the first half of November, when rain and thunderstorms can occur across the island. This clears up as December nears, with conditions getting balmier by the day during the second half of November.
In general when it does rain, it’s unusual for the rain to last all day, with downpours more often being short and sharp, often with a number of inches falling in just a matter of minutes
As with many South-East Asian destinations, the period from December to mid-April is considered the peak season for overall weather and therefore overall visitor numbers. Whilst there is good reason for this, there are equal benefits to travelling outside of this period, with the shoulder season often providing the best of both worlds; namely great weather and a lower visitor numbers.
There is not really a good or bad time to visit Vietnam, as during most months of the year you will experience both sunshine and rain in varying quantities.
Vietnam is typically warm and humid and the weather can vary significantly from one region to another due to the countries length. Most travelers divide the country into three when deciding when best to travel: the North and Far North, Central and Southern.
Far North and North:
Sapa is divided into two seasons – the dry season runs from October to late March and the wet season lasting from April to September. It can get very cold in December and January, especially at night. The best trekking conditions in Sapa and the northwest are from September to November and from March to May.
Hoi An, Hue & Danang in the centre of Vietnam have hot and dry weather from mid-January to late August, with temperatures often reaching the mid-30’s °C.
The climate of the south is split into two simple seasons, wet and dry. The dry season begins in November and ends in April/early May with late February to May being slightly hotter and with higher humidity. The wet season lasts from May to early November with the months from June to August receiving the highest rainfall of the year. Throughout much of the wet season rainfall is generally heavy but short lasting, often occurring in a mid-afternoon heavy downpour. The average temperatures in the south range between 25 – 35°C year round.
