- Spring is peak season for most green and first-flush teas: China’s pre-Qingming Longjing is picked before about April 5, Japan’s shincha runs late March through May, and Korea’s prized ujeon is plucked before Gogu (around April 20).
- Darjeeling and Assam reward two different trips: the delicate first flush arrives late February to April, while the muscatel second flush peaks from late May into June and July.
- Sri Lanka’s most coveted cup is a summer event: the Uva quality season runs roughly late July to mid-August, when dry ‘cachan’ winds concentrate flavour in the Eastern Highlands.
- Taiwan’s high-mountain oolong has two prime windows: spring (mid-April to early May at altitude) and winter (late October into November), the only two harvests that yield premium tea.
- Some regions ignore the calendar: Kenya plucks year-round with crop peaks in March-June and October-December, and South Africa’s rooibos is a Southern-Hemisphere summer harvest (January-March).
How Tea Seasons Actually Work
Tea is an agricultural crop, and like wine grapes, the leaf changes character with the season it is picked. A ‘flush’ is simply a fresh growth of shoots after a rest period, and the first flush of the year is usually the most prized because the plant has spent months of dormancy concentrating amino acids and aromatics into a small number of tender buds. As the year warms, growth speeds up, the chemistry shifts toward stronger catechins, and the flavour moves from delicate and floral toward bold and brisk. For more, see our guide to Darjeeling tea estate stays.
That is why timing matters so much for a tea-focused trip. Visit Darjeeling in March and you taste light, green, almost champagne-like first flush; come back in June and the same gardens are producing dark, fruity, muscatel second flush. The catch is that exact dates move every year with the weather and shift with elevation, so treat the windows below as reliable seasons rather than fixed calendar entries. The single most useful planning rule: decide whether you want to see picking and taste the freshest leaf, or simply walk lush green hillsides in good weather, because those are often two different months.
Spring: The First-Flush and Green-Tea Window (March-May)
Spring is the headline season for most of the world’s green teas and for the celebrated first flushes of the Himalayan black-tea belt. If you only travel once for tea, this is the window that rewards it most. For more, see our guide to Shizuoka tea gardens.
China: Pre-Qingming Longjing (late March-early April)
China’s most famous green tea, Longjing (Dragon Well) from the hills around Hangzhou, is defined by a single date on the lunar calendar. The most prized grade, ‘Mingqian’ or pre-Qingming, must be picked before the Qingming Festival, which falls around April 4-5 each year. These early leaves are only the youngest buds with one or two small leaves, tender and high in the amino acid theanine, and the picking window is famously short. Arrive in the last week of March or the first days of April and you can watch hand-plucking on the terraces before the rush. Hangzhou is an easy high-speed-rail hop from Shanghai, which makes this one of the most accessible spring tea pilgrimages in Asia.
Japan: Shincha and Ichibancha (late March-May)
Japan’s first flush, called ichibancha, and the very freshest expression of it sold as shincha (literally ‘new tea’), sweeps up the country from south to north as spring warms. Picking begins in the southern lowlands of Kagoshima and Tanegashima in late March, reaches the famous gardens of Shizuoka through April and May, and arrives in cooler Nara around May and June. The leaves accumulate sweetness and savoury depth over winter dormancy, which is what gives shincha its prized fresh, grassy-sweet character. Golden Week in early May is both the heart of harvest and a busy domestic travel period, so book accommodation early if you want to combine picking season with the famous gardens of Uji or Shizuoka. For more, see our guide to Japanese green tea varieties.
Korea: Ujeon Before the Rains (early-late April)
Korean green tea is graded by exactly when it is picked. The top grade, ujeon, is harvested before Gogu, the spring-rain term that falls around April 20, and consists of only the tiniest first buds. The next grade, sejak, is plucked from late April into early May. The country’s most photogenic tea destination, the Daehan Dawon plantation in Boseong, comes alive in this window: most visitors arrive between late March and late April to see the first new leaves emerge on the terraced bushes, and the Boseong Green Tea Festival runs every May with tastings and hands-on activities. May temperatures sit at a comfortable 15-22C, ideal for walking the fields.
Darjeeling and Nepal: The Spring First Flush (late February-April)
High in the Himalayas, Darjeeling‘s first flush begins after winter dormancy from late February to mid-April, producing the light, brisk, floral teas that command premium prices at auction. Just across the border, the Ilam district of eastern Nepal follows a near-identical rhythm, with its first flush running late March to early May and its plucking season stretching March to November. Spring here means clear-ish mountain mornings and gardens busy with selective hand-picking. It is the most delicate tea these mountains produce, and tasting it on the estate days after it is made is a genuinely different experience from drinking it months later.
Summer: Muscatel, Monsoon, and the Uva Window (June-August)
As spring tips into summer, the character of the harvest changes and the geography of ‘best season’ shifts toward the second flush of India and Nepal and the unique quality season of Sri Lanka’s Uva highlands.
Darjeeling and Assam: The Second Flush (late May-July)
The second flush is, for many drinkers, the finest harvest of the year in the Indian black-tea regions. Darjeeling’s second-flush leaves are picked from late May into June and carry the famous ‘muscatel’ note, a rounded, fruity, less-astringent character that connoisseurs prize above the spring crop. In Assam, the low-lying black-tea heartland to the east, the bushes resume flushing by mid-May and the peak comes in June and July, when the quintessential malty Assam is made, often studded with golden tips. Summer is hot and humid in Assam, so plan estate visits for early morning and expect the dramatic, leaf-laden gardens that define India’s largest tea region.
Sri Lanka: The Uva Quality Season (late July-mid-August)
Ceylon estates produce tea all year, but the Uva district in the eastern highlands has a short, famous window when its sought-after seasonal teas are made: roughly late July to mid-August, occasionally stretching into early September. During these weeks the east of the island sits in a dry spell while dry ‘cachan’ winds blow in off the Bay of Bengal, and that combination of drought and fierce wind concentrates an unmistakable aromatic character in the leaf. The hill-country towns of Nuwara Eliya and nearby Ella are the practical bases. Note the dual calendar here: late July to late August is the cup connoisseurs chase, while Nuwara Eliya’s clearest, greenest weather for general sightseeing falls in the separate dry stretch from roughly January to March.
Autumn and Winter: Late Flushes and High-Mountain Oolong (October-December)
The cool end of the year is quieter on most estates, but it holds two genuinely special harvests: the autumnal flush of the Himalayas and the winter oolong of Taiwan’s highest peaks.
Darjeeling: The Autumn Flush (October-November)
After the monsoon ends in mid-September, Darjeeling’s bushes resume growth and are harvested again in October and November. The autumnal flush yields a darker leaf and a full-bodied, naturally fruity cup, and it coincides with some of the clearest post-monsoon mountain views of the year, which makes autumn an underrated time to visit the gardens.
Taiwan: Spring and Winter High-Mountain Oolong
Taiwan’s prized high-mountain oolong from Alishan, Lishan and the other peaks is harvested only twice a year for premium grade, and those two harvests are the reason to time a visit. Spring tea is picked from mid-March to early May (roughly mid-April to early May for Alishan specifically), moving up the mountains from lower elevations to higher; winter tea follows from late October into late November, running in reverse from the highest gardens downward. Summer and autumn pickings do not produce premium oolong, so spring and winter are the windows that matter. Winter oolong in particular is celebrated for its clear, refined liquor, low bitterness and crisp ‘cold aroma,’ and a journey from Taipei up to the Alishan tea trails in either season pairs spectacular scenery with the harvest.
The Year-Round Exceptions: Kenya and Rooibos
Not every tea region follows a flush calendar. Kenya, Africa’s largest producer, sits on the equator in highlands between roughly 1,500 and 2,700 metres around Mount Kenya, the Aberdares and the Kericho plains, and plucks tea continuously through the year. Production has two crop peaks that track the rains, March to June and October to December, but there is no single ‘season’ to chase, which makes Kenya a flexible destination weather-wise.
South Africa’s rooibos flips the hemisphere and the plant entirely. The red bush, Aspalathus linearis, grows only in the Cederberg Mountains north of Cape Town, and it is harvested in the Southern-Hemisphere summer, between January and March, just after the first summer rains when the plants are at their leafiest. A summer visit to the Cederberg is the way to see sickles and cutters at work and the cut bush laid out to ferment and dry in the sun into its signature reddish-brown.

How to Plan a Trip Around the Harvest
Start by choosing your goal. If you want to witness picking and taste the freshest possible leaf, build the trip around a single region’s flush and arrive at its start rather than its peak, since the earliest premium leaf often sells out fast. If your priority is scenery and comfortable walking, the best-weather month and the best-tea month can differ, as Sri Lanka’s split calendar shows. Always treat published windows as moving targets: elevation pushes harvests later (Taiwan’s highest Lishan gardens are the last to be picked in spring), and an early or late spring can shift dates by a week or two.
Two habits help. First, confirm timing with the specific estate or a local operator before booking flights, because a garden 500 metres higher up the valley may run a fortnight behind its neighbour. Second, layer your itinerary so each tea region pairs with reliable sights nearby, so a foggy morning or an off-week harvest still leaves you with a memorable trip. A little flexibility in dates pays off more than any single ‘perfect’ week.

Frequently Asked Questions
What is the best time to visit tea plantations?
Spring (March-May) suits most regions: it is when China’s Longjing, Japan’s shincha, Korean green tea and the Himalayan first flush are picked. But the ideal month depends on the region and your goal. For Sri Lanka’s prized Uva tea, aim for late July to mid-August; for Taiwan’s high-mountain oolong, target spring or late autumn instead.
When is the Darjeeling first flush harvested?
Darjeeling’s first flush is harvested from late February to mid-April, after the bushes emerge from winter dormancy. It produces the light, brisk, floral teas the region is known for. The richer, fruity ‘muscatel’ second flush follows from late May into June, and a darker autumnal flush is picked in October and November after the monsoon ends.
What month is Japanese shincha (new tea) available?
Japanese shincha, the first flush of the year, is picked from late March in the warm south (Kagoshima, Tanegashima) and progresses north into May and June in cooler regions like Nara, with the famous gardens of Shizuoka harvesting through April and May. Early May, around Golden Week, is the heart of the season but also a busy domestic travel period.
When is rooibos harvested in South Africa?
Rooibos is harvested in the Southern-Hemisphere summer, between January and March, just after the first summer rains when the plants are at their leafiest. It grows only in the Cederberg Mountains north of Cape Town. A summer visit lets you see the cut bush laid out in the sun to ferment and dry into its signature reddish-brown colour.
Can you visit tea plantations year-round?
Yes, in some regions. Kenya plucks tea continuously all year, with crop peaks in March-June and October-December, so any month works. Sri Lanka’s estates also produce year-round, though Uva’s prized seasonal teas are made only from late July to mid-August. Flush-driven regions like Darjeeling, Japan and Taiwan have specific harvest windows worth planning around.
When is Taiwan high-mountain oolong harvested?
Taiwan’s premium high-mountain oolong is picked twice a year: spring tea from mid-April to early May at higher elevations such as Alishan, and winter tea from late October into November. Only these two harvests yield top-grade oolong. Winter tea is especially prized for its clear, refined liquor, low bitterness and crisp aroma.
