Welcome to May—the final chapter of Nepal’s glorious spring trekking season. The crowds begin to thin, the trails are still lush and colorful, and the skies, though starting to turn, often stay clear until late in the month. If you’re looking for a slightly quieter Himalaya experience without sacrificing good weather, May is your sweet spot.
But it’s also a month of change. The temperature is rising, pre-monsoon clouds begin to flirt with the peaks, and the smell of summer hangs in the air. Think of it as the last call for crisp mountain views before the clouds roll in.
What’s the Weather Like in May?
May is warm and increasingly humid in Nepal, especially in lower elevations. In the mountains, though, it remains pleasant and dry for the most part, especially in the first two-thirds of the month.
| Region | Day Temp | Night Temp | Weather |
|---|---|---|---|
| Kathmandu | 20°C to 32°C | 15°C to 20°C | Hot, humid, occasional afternoon showers |
| Namche Bazaar | 8°C to 15°C | 2°C to 6°C | Mild, some clouds |
| Ghorepani (ABC) | 10°C to 20°C | 5°C to 10°C | Lush, warm, increasing haze late in month |
Visibility: Excellent in early May, slightly hazy by mid-to-late May
Rain: Pre-monsoon showers in late afternoons/evenings, especially after mid-May
Trail Conditions: Excellent, with some humidity in lower forests
Why Trek in May?
1. Spring’s Final Show
Rhododendrons may have peaked, but the high-altitude wildflowers take over. You’ll still see color in the forests and greenery across the terraced hills.
2. Fewer Crowds
Trekkers thin out after April, which means quieter trails and easier bookings in tea houses. Perfect if you’re looking for a bit of solitude without giving up spring beauty.
3. Warmer Evenings
Chilly tea house nights? Not in May. The higher nighttime temperatures make sleeping more comfortable and your gear list a little lighter.
4. Great for Higher Altitude Routes
May is excellent for high passes like Thorong La, Larkya La, and Cho La, which remain stable and relatively snow-free (unless it’s a freak late-spring snowfall).

Treks to Consider with Caution

Travel Tips for May
-
Start early: Clouds and rain tend to roll in by mid-afternoon. Morning starts are your best friend.
-
Keep an eye on the forecast: Pre-monsoon showers are unpredictable. Be flexible with your daily plan.
-
Dehydration is real: May heat is sneaky, especially at lower altitudes. Drink more water than you think you need.
-
Mosquitoes & leeches: Starting to show up in humid areas. Bring repellent if trekking in lowland zones.
What to Pack in May
May is warm but not yet full monsoon. You still need layers for high altitudes but can go lighter on cold-weather gear.
Essentials:

Lightweight long-sleeve trekking shirts
-
Convertible trekking pants or light trousers
-
Windproof shell for high-altitude breezes
-
Down jacket for early morning base camp views

Packable rain jacket

Waterproof cover for your backpack

Quick-dry clothes and socks
Getting There: Still Smooth Sailing
-
Flights to Lukla: Still operating daily but can experience morning fog and delays, especially late May

Road travel to Pokhara, Syabrubesi, and other trailheads remains open and smooth
-
Domestic air travel is reliable, with some heat-related visibility issues toward the end of the month
Offbeat May Trekking Alternatives
If you’re worried about haze or rain in popular regions, these alternatives shine in May:
-
Nar Phu Valley: Remote, culturally rich, and dry
-
Upper Dolpo: Requires more time and permits, but pristine and untouched
-
Khopra Ridge: Less crowded than ABC, with sweeping views and warm tea houses
Is Trekking in May Worth It?
Absolutely — with a little planning.
If you’re trekking before the 20th of May, you’re in for spectacular trails, warming weather, and fewer people. Even beyond that, treks like Upper Mustang, Manaslu, and EBC can still deliver an incredible experience with a bit of flexibility.
So lace up your boots, pack your shell jacket, and chase those final spring views before the monsoon curtain drops. May is Nepal’s underrated window — not perfect, but often unexpectedly glorious.
