Traveller notes on Punakha in August
Other months in Punakha
Bhutan's forum places May right at the edge of monsoon onset, hazy and cloudy with a real chance of rain most days, but posters were consistent that forecasts tend to overstate it - many days bring only brief showers or overcast skies rather than a genuine downpour, and multiple regulars still called May a pleasant month to visit overall. Temperatures in this range run roughly 8-20C depending on elevation and time of day. Roads connecting Paro, Thimphu and Punakha stay in generally good shape this early in the season, with only the occasional minor landslide in hillier stretches rather than major closures.
Forum posters describe mid-November as generally good Bhutan weather - clear skies, plenty of sun, and daytime conditions comfortable in a light jacket or hoodie with a heavier layer needed once the sun goes down. Posters specifically flag Punakha as running noticeably warmer than higher-elevation stops like Paro or Thimphu, given its much lower valley elevation (around 1,200m versus roughly 3,000m), often 10C or more milder at the same time of year. September through November is generally described by posters as Bhutan's dry, pleasant post-monsoon stretch, though posters also note a lingering shower or two is still possible into November before the fully dry winter pattern sets in, so packing for one isn't unreasonable even on an otherwise sunny-leaning trip.

Glacial flood risk on the rivers
1 Jun – 15 Oct · usuallyFlood seasonThe Mo Chhu and Pho Chhu, which meet at the dzong, are fed by glacial lakes upstream that have burst before: floods in 1957, 1960, 1994 and 1996 each damaged Punakha Dzong, the worst killing 23 people. The risk sits in the monsoon and glacier-melt months, not the dry winter. Source ↗
