Opening week (Akshaya Tritiya ~26 April): temperatures still cold 8–14°C day, 1–5°C night. Snow patches possible on the Janki Chatti to Yamunotri trek in early May. June — Day 14–18°C, night 6–10°C, but monsoon approaches from mid-June. Late June becomes rainy with potential for landslides on the approach road.

What is the weather at Yamunotri in September?

September is the best month to visit Yamunotri: Day temperature 12–18°C, night 4–8°C. Monsoon retreats from Uttarakhand by late September — skies clear, visibility excellent. The trek from Janki Chatti (2,650 m) to Yamunotri (3,291 m) is in perfect condition — trails dry, no landslide risk, cool air. The Yamuna river is full and roaring but within its banks. Rhododendron and wildflowers in late bloom. Smaller crowds than May–June. October: temperatures drop (day 8–14°C, night 0–4°C), drier, excellent autumn weather. Good for a quieter Yamunotri experience before closing.

Should I visit Yamunotri in July or August?

Generally not recommended. Yamunotri in July–August: Heavy monsoon rainfall (300–500 mm/month). High landslide risk on the Barkot–Janki Chatti road and on the Janki Chatti–Yamunotri trek trail. Flash floods in the Yamuna gorge are possible. Trek trail can be very slippery and dangerous. The Uttarakhand government and the Char Dham Devasthanam Board actively discourage yatra during peak monsoon and sometimes restrict access. If you must travel in July–August: monitor SDRF alerts, travel only in morning before 12 PM, avoid after heavy rain, travel with a group. Not recommended for solo travellers or first-timers.

Planning

Janki Chatti to Yamunotri trek weather impact:
The 6-km trek (641 m ascent) is the crux of the Yamunotri visit — weather on the trail directly impacts safety and enjoyment. In May: trails dry, possible snow patches above 3,000 m. In September: perfect trail conditions — dry, cool, good grip. In July–August: slippery, flood-prone sections near stream crossings, serious landslide risk on the upper section near Yamunotri (many rockfalls in this gorge during heavy rain). In October: trails dry and firm, cold in morning, perfect for trekking.

Barkot and Janki Chatti weather (lower altitude):
Barkot (1,220 m, trek gateway) is approximately 2,000 m lower than Yamunotri. Summer temperatures: 20–28°C day. Monsoon: warm and wet. In July–August, even Barkot is affected by landslides on the approach roads. The Barkot–Janki Chatti section (13 km mountain road) is landslide-prone in peak monsoon.

Travel Tips

September vs May — September wins at Yamunotri: May has the advantage of the opening ceremony and fresh season energy. But September is better for the trekking experience — dry trail, clear mountain views, fewer crowds, easier accommodation availability, and the Yamuna running full and beautiful. If you can choose, September is the clear winner.
Carry a light rain jacket even in September: Afternoon showers are possible even in post-monsoon September in the Himalayan valleys. Bring a light packable rain jacket or poncho for the trek — it fits in a day pack and takes up minimal space.
Avoid the trek in monsoon rain: The Janki Chatti–Yamunotri trail has steep exposed sections and several stream crossings that become dangerous in heavy rain. Check the weather forecast (available at Barkot) before starting the trek. If rain is forecast, delay to the next morning.

What to Wear

May: fleece jacket (morning/evening), t-shirt (afternoon), warm hat and gloves for early morning trek start.
September: same as May. Layer up for the 6 AM–7 AM pre-dawn start from Janki Chatti.
October: warm mid-layer + windproof outer, thermal inner for nights. Days are sunny but cold at 3,291 m.
November (closing): serious winter gear — down jacket, thermal pants, warm gloves, hat. Not for casual visitors.
