Rain, Rain, Go Away: Unpredictable Seasons and the Changing Rhythms of Bhutan
If Jigme had his way, he would gather his harvest beneath a bright, clear sky.
Every year, toward the end of September, Bhutan celebrates Thruebab (Blessed Rainy Day). On this sacred day, all natural water sources are believed to become purified, capable of cleansing accumulated bad karma. For generations, Thruebab also served as a practical milestone: it marked the official end of the monsoon and signaled the start of the autumn harvest.
This year, however, the monsoon refused to depart.
After September 23rd, rain continued to shower across the country straight through September and into late October. In Paro, farmers were left helpless as their cut paddy—spread across fields to dry for threshing—lay soaking in relentless rain. Following age-old traditions and seasonal certainties, farmers had cut their crops expecting the skies to clear after Thruebab. Instead, a brief day or two of sunshine gave way to continuous downpours, leaving farmers to witness heartbreaking post-harvest losses.
Waiting for Clear Skies
Down in Tsirang, Barsha wished the rain away during Dashain. She could not recall ever celebrating the festival under soggy, overcast skies. After waiting the entire year for Dashain, she longed for a warm, sunny day. Because of the persistent downpours, many of her family members and relatives had to postpone their travels, waiting for the weather to clear so they could gather and receive Tika from their elders and kin.
Neither Jigme nor Barsha fully understood why the rains lingered so long past their welcome.
Historically, Bhutan’s climate followed well-known rhythms:
Northern Region: Sparse annual precipitation averaging around 40 millimeters, mostly as snow.
Central Temperate Valleys: Yearly rainfall averaging roughly 1,000 millimeters.
Southern Foothills: Subtropical downpours reaching up to 7,800 millimeters annually.
In Thimphu, winter months (December through February, stretching into March) brought a strong likelihood of snow, with light average rainfall around 20 millimeters a month. Rains would gradually build toward a peak of 220 millimeters in August, accumulating to an annual total of about 650 millimeters. Jigme’s harvest decisions and Barsha’s festive expectations were anchored in these predictable patterns passed down over generations.
Searching for New Certainties
In recent years, Bhutan’s climate patterns have subtly shifted. The lingering autumn rains stretching into late October—paired with increasingly uncertain winter snowfall in main Thimphu city—signal that the old references are changing.
This shift leaves us with profound questions for the future:
What new benchmarks will farmers rely on to time their planting and harvesting?
How will younger generations adjust as ancestral knowledge faces unpredictable weather?
How prepared are we as a community to modernize post-harvest techniques and safeguard hard-earned yields against sudden climate shifts?
As the rain falls past its appointed hour, it reminds us that adapting to a changing climate isn't just a global debate—it is a deeply personal reality played out in the paddy fields and family homes of Bhutan.
