Nepal Weather Forecast This Week 2025: What Tourists, Trekkers, and Communities Need to Know
Introduction: Monsoon on the Move—And Why This Week Matters
Nepal’s monsoon typically tapers off between late September and early October, but it can “pulse” before withdrawing—delivering bands of intense rain across the hills and Terai, with spillover showers into the high valleys. Nepal weather forcast this week’s forecast points to widespread showers and periods of heavy rain across multiple provinces, raising risks of localized floods, swollen rivers, landslides, and travel disruptions—especially along key tourist and trekking corridors. Nepal’s Department of Hydrology and Meteorology (DHM) has urged special caution heading into the weekend, noting the potential for heavy monsoon rains and flash-flood conditions through early next week.

Kathmandu Valley (Bagmati)
- Pattern: Humid, mostly cloudy, with recurring thunderstorms and periods of rain.
- Temps: Highs around 23–27°C, lows 16–18°C through mid-week.
- Impacts: Urban waterlogging on heavy-rain days; minor road delays; domestic flight knock-ons possible if storms line up over the Valley.
Pokhara & Lower Annapurna (Gandaki)
- Pattern: Cloudy with heavy showers, particularly Saturday, and scattered storms on adjacent days.
- Temps: Highs 26–32°C (cooler during rain), lows 16–19°C.
- Risks: Short-notice ATC holds at Pokhara airport during downpours; slippery trails in Phewa-side hills and lower Annapurna approaches.
Lukla / Everest Gateway (Khumbu, Solukhumbu)
- Pattern: Cool and mostly cloudy with frequent rain spells through the week.
- Temps: Highs 15–21°C, lows 8–10°C.
- Risks: Low cloud and rain commonly disrupt Lukla flights in early October; expect morning backlogs and rolling delays.
Jomsom / Mustang Rain-Shadow Edge
- Pattern: Mostly cool, with intermittent showers; heavier bursts possible as the system pulses.
- Temps: Highs 14–20°C, lows 4–6°C (cold mornings).
- Risks: Jomsom winds plus passing showers may limit visibility; plan buffer days for inter-valley flights/jeeps.
Eastern Terai (Biratnagar; Koshi)
- Pattern: Cloudy with thunderstorms, steady rain lining up over the weekend; humid and hot between cells.
- Temps: Highs 27–34°C, lows 23–27°C.
- Risks: Urban flooding, water-logging, and river rise in downstream belts; watch small rivers for sudden surges.
Mid-Western Terai (Nepalgunj; Lumbini/Karnali)
- Pattern: Humid with showers, thunderstorms most likely in the afternoons; hotter mid-week.
- Temps: Highs 28–35°C, lows 22–24°C.
- Risks: Short-lived but intense downpours; localized flooding in low-lying wards.
Government/Media Guidance: DHM and disaster authorities caution that heavy monsoon rains could trigger flash floods in small rivers and raise water levels in major basins (Koshi/Gandak/Bagmati) through Monday; travelers should track advisories closely.
Aviation Advisory: Nepal’s civil aviation regulator issues seasonal monsoon guidance on reduced visibility, wind shear, and convective storms—conditions likely to recur this week, especially at Lukla, Pokhara, and Jomsom. Expect delays/cancellations during convective windows. (flightsafety.caanepal.gov.np)
Impact on Tourism: Treks, Flights, and Safety
Trekking Corridors
- Everest (EBC approach via Lukla): Persistent cloud and showers increase the chance of flight delays into/out of Lukla; on-trail, expect slick stone steps, leeches at lower altitudes, and reduced visibility above tree line. Allocate at least one buffer day on both ends.
- Annapurna (ABC/ACT): Heavy rain Saturday may cause landslide debris on jeep roads and muddy traverses below 3,000 m. Consider jeep repositioning to skip road-affected stretches; watch for stream crossings rising after mid-day.
- Manaslu Circuit: Narrow trails above the Budhi Gandaki are vulnerable to rockfall after sustained rain; check bridge status daily with your guide; be ready to halt at Sama/Samdo if forecasts tighten.
- Langtang Valley: Forested sections can get leechy and slick; cloud can shut down views from Kyanjin—but safety first: avoid narrow landslide gullies after heavy showers.
- Upper Mustang: Usually drier, but this week still shows passing showers around Jomsom; winds + showers reduce visibility—plan flexible transfers.
Flights & Road Travel
- Lukla / Pokhara / Jomsom: Morning MVFR/IFR conditions (low cloud/visibility) likely on multiple days; ATC flow control may stack departures or cancel sectors outright. (flightsafety.caanepal.gov.np)
- Highways & rural roads: Expect slips, washouts, and delays on Muglin–Pokhara, Muglin–Narayanghat, Prithvi Highway, and feeder roads to trailheads. Night driving is not recommended during heavy rain windows.
Practical Recommendations for Tourists (This Week)
- Build 1–2 buffer days around treks and domestic flights.
- Keep route plans flexible (alternative trailheads, jeep assists, or extra acclimatization day).
- Trek early mornings to beat afternoon convection; avoid gullies and steep cut-slopes after heavy rain.
Confirm lodge availability along safer halts; consider down-valley pauses during red-flag days.
Impact on Festivals and Local Life
October’s festival calendar (including Dashain period events in some communities) often draws large family movements. Heavy rainfall can:
- Delay processions and outdoor rituals, with festival disruption Nepal likely where courtyards and streets flood.
- Slow inter-district travel for family gatherings, extending bus journeys and crowding shelters/stations.
- Affect schools and offices with late starts or temporary closures after night-time downpours.
- Interrupt agricultural work, especially harvest logistics and river-irrigated plots in the Terai.
Yet communities remain resilient: neighborhood committees clear drains; local volunteers guide traffic around flooded stretches; ward offices coordinate sandbags and pumps in low-lying lanes—measures that reduce exposure while festivities adapt.
Natural Calamities & Safety Measures
Key Risks
- Landslides in Nepal: Saturated slopes in the middle hills (250–2,500 m) are susceptible after multi-day rain. Avoid loitering below fresh scarps and overhanging cliffs.
- Flood Warning Nepal: Watch the Koshi and Gandak systems for rising levels; culverts can overflow suddenly after cloudbursts. Downstream states in India have already signaled high alert given upstream rain in Nepal.
- Urban Flash Floods: Kathmandu, Pokhara, Biratnagar neighborhoods can waterlog quickly; avoid basement accommodations during heavy-rain nights.
Official Warnings & Actions
- DHM advisory (Oct 2): Exercise special caution Oct 4–6 due to a renewed heavy-rain pulse; flash-flood potential in small rivers; larger rivers likely to rise.
- Aviation (Monsoon Circular 2025): Crews and operators are directed to heighten preparedness for convective storms, low visibility, and wind shear—expect conservative dispatch decisions this week. (flightsafety.caanepal.gov.np)
Advice for Tourists and Locals: Staying Safe in Heavy Rain
For Trekkers & Guides
- Start early, finish early. Convection peaks in afternoons.
- Reroute when needed. Do not push through active landslide zones; wait or detour with local guidance.
- Footing & gear: Poles, traction (microspikes for slick rock), and gaiters; pack warm layers—rain-cooled evenings are chilly even at modest altitudes.
- Comms: Carry a power bank; pre-download offline maps; share your GPS track with your operator.
For Drivers
- Avoid night driving on hill highways; watch for rockfall after prolonged rain.
- Cross spillways/fordings only with local advice; water depth and undercut edges can mislead.
- Keep hazards, triangles, and tow ropes handy; ensure wipers and lights are in good order.
For Everyone at Low Altitude
- Secure drains and gutters around homes/shops; move electricals off the floor.
- Avoid open manholes and fast-flowing roadside channels at night.
- Keep a go-bag: torch/headlamp, dry snacks, basic meds, copies of IDs and insurance.
Insurance & Information
- This week, treat travel insurance with helicopter evacuation as essential for trekkers.
Check DHM bulletins and local municipality pages twice daily; re-confirm flight status the night before and at dawn on the day of travel.

Enjoy the Season—But Read the Sky and Respect the River
Even at its stormiest, Nepal remains magnetic—clouds boiling over ridgelines, rivers the color of slate, prayer flags snapping over wet courtyards. The key to enjoying it safely is situational awareness and flexibility. If you’re here for treks, temples, or family festivals, build in buffer time, heed local guidance, and let the weather set the rhythm.
This weekly weather update Nepal isn’t a reason to cancel plans—it’s a call to plan smart and travel responsibly. Support community resilience efforts, book with operators who prioritize safety, and remember: in the Himalaya, good judgment is the best gear you carry.
Note: Forecasts are dynamic; check the latest bulletins before traveling.
