Asia in May: Weather, Crowds & What to Expect

Western Asia & the Middle East (Turkey, Levant - Israel, Lebanon, Jordan, Syria, Iraq, Iran, Arabian Peninsula - Saudi Arabia, UAE, Oman, Qatar, Kuwait, Yemen)

Warmer, sunnier days arrive for coastal Turkey and Lebanon, and the Arabian Peninsula heats up noticeably during daylight - Dubai and Doha become more reliably warm and dry. Inland Iran and Iraq see clearer skies but still cool nights, while mountain snowpack thins; seismic hiking routes start to reopen. Travelers should expect river valleys and archaeological sites to be muddy from winter melt and pack sturdy, waterproof shoes.

Central Asia & the Caspian Steppe (Kazakhstan, Uzbekistan, Kyrgyzstan, Turkmenistan, Tajikistan)

Full spring warmth and clear skies bring very agreeable conditions for city visits and trekking approaches: April sees carpets of wildflowers in Kyrgyz valleys and comfortable temperatures in Tashkent, while Turkmen desert landscapes are pleasantly dry. The best window for cross-country drives opens as mountain passes start to clear, but strong daytime winds still make camping on the steppe blustery; sunscreen and a light jacket are essential.

Siberia & the Russian Far East (Yakutia/Sakha, Krasnoyarsk, Irkutsk, Kamchatka, Vladivostok and Magadan)

June opens the brief but intense summer: Siberian interiors and around Lake Baikal experience mild, mosquito-heavy weather with long daylight hours, while Kamchatka’s volcanic landscapes bloom and support wildlife viewing. This is the peak season for the Trans-Siberian Railway and for wilderness trekking in the taiga; book accommodation and guides ahead and bring robust insect repellant and lightweight rain gear.

The Himalaya & Tibetan Plateau (Nepal, Bhutan, Tibet/Autonomous Region, Sikkim and northern Indian ranges)

By this stage the pre-monsoon trekking window is in full swing: clear mornings, warm afternoons and blossoming rhododendrons make for excellent trekking conditions around Pokhara and lower Everest regions. The Tibetan Plateau has short, dry days that are strong on sun and cold at night - ideal for high-altitude touring if you can tolerate sharp diurnal swings. Crowds peak on standard routes; book teahouses and permits ahead.

South Asia (India excluding high Himalaya, Pakistan lowlands, Bangladesh, Sri Lanka, Maldives)

The southwest monsoon typically breaks over Kerala and the southwest coast, bringing torrential rains and dramatically different travel conditions; heavy, sustained precipitation spreads through most of India and sets the tone for the next few months. Bangladesh and the eastern coasts also see increasing rain and risk of cyclones in active years. Beach and hill destinations on the western side of India can be very wet and slippery - indoor plans and flexible itineraries are crucial.

East Asia (China - coastal and central provinces, Japan, South Korea, Taiwan)

Mild, often sunny conditions in much of Japan, Korea and central China make this prime travel season; Beijing and Seoul are comfortable for full-day urban exploration, and late-spring festivals draw visitors. The East Asian rainy season typically starts to build in pockets around late May-June (Meiyu in China and Baiu in Japan), especially affecting the Yangtze corridor and western Japan. Book accommodations early for popular cultural events.

Southeast Asia (Mainland: Thailand, Vietnam, Cambodia, Laos, Myanmar; Maritime: Malaysia, Singapore, Indonesia, Philippines, Borneo, Timor)

Widespread rain makes lowland trekking difficult and some rural roads impassable across mainland Southeast Asia; Mekong tributaries swell and outdoor temples can be slippery. On the other hand, western Indonesian islands and parts of Borneo can be in a more settled phase, offering better wildlife-spotting opportunities. Mosquito-borne disease risk is higher - pack repellant and take appropriate health precautions.
