The best time to trek Mardi Himal is October and November. After the monsoon, mornings at High Camp are the clearest of the year, the trail is dry, and the ridge has no snow. December is almost as clear and far quieter, if you don't mind cold nights. April is the month for rhododendrons, but clouds close in earlier in the day.
The months to be careful with are February, when heavy snow can block the climb to the Viewpoint, and June to August, when rain brings leeches to the lower forest.
That's the short version. The rest of this guide is what our guides actually see on the ridge, month by month, so you can choose the right week for you.
| If you want… | Go in | Watch out for |
|---|---|---|
| The clearest mountain views | October or November | Dashain and Tihar crowds |
| Clear views with fewer people | Late November or December | Freezing nights at High Camp |
| Rhododendron forest in bloom | April | Cloud by mid-morning |
| Snow on the ridge | January | Microspikes and warm gear needed |
| Your first trek, easiest conditions | Late October or early November | Book lodges early |
| An empty trail | June to August | Rain and leeches |
This is what our guides typically find on the ridge each month. A single storm can change a week, so we check conditions again before every departure.
Here’s a shorter version with just the key points:
| Month | Conditions | Verdict |
|---|---|---|
| January | Clear, snowy, cold | Good for snow lovers |
| February | Heavy snow, possible closures | Risky; keep a spare day |
| March | Good views, early snow | Good; flowers bloom late |
| April | Clear early, rhododendrons | Best for spring |
| May | Clear early mornings | Best in early May |
| June | Rain, leeches | Quiet but wet |
| July | Heavy rain, many leeches | Hardest month |
| August | Heavy rain, leeches | Better in late August |
| September | Improving weather | Good from mid-month |
| October | Clear, dry, crowded | Best overall; book early |
| November | Clear, cold nights | Excellent for trekking |
| December | Clear, cold, quiet | Excellent with warm gear |
High Camp (3,580m) is where you'll spend the coldest night. These are typical ranges; wind on the ridge makes it feel colder, and the Upper Viewpoint (4,200m) is below freezing at sunrise most of the year.
| Month | Forest Camp (2,600m) day / night | High Camp (3,580m) day / night |
|---|---|---|
| January | 8–12°C / -2–2°C | 0–6°C / -6 to -12°C |
| February | 9–13°C / -1–3°C | 2–7°C / -5 to -10°C |
| March | 11–15°C / 2–6°C | 5–10°C / -5–0°C |
| April | 14–18°C / 5–8°C | 8–14°C / -2–3°C |
| May | 16–20°C / 8–11°C | 10–15°C / 2–6°C |
| June | 17–21°C / 10–13°C | 10–16°C / 5–9°C |
| July | 17–21°C / 11–14°C | 11–16°C / 6–9°C |
| August | 17–21°C / 11–14°C | 11–16°C / 6–9°C |
| September | 15–19°C / 9–12°C | 10–14°C / 2–6°C |
| October | 13–17°C / 5–8°C | 8–12°C / -2–2°C |
| November | 11–15°C / 2–5°C | 5–10°C / -5–0°C |
| December | 9–13°C / -1–3°C | 2–8°C / -5 to -10°C |

Autumn is when Mardi Himal is at its best. The monsoon washes the dust out of the air, and from mid-September the mornings at High Camp turn reliably clear. On a good October morning you can see Machhapuchhre, Annapurna South, and Hiunchuli sharp against the sky, often until late morning.

Spring is the second-best season, and for many people it's the favourite. From late March through April, the forest between Forest Camp and Low Camp turns red and pink with rhododendrons.
The trade-off is the view. In April and May, our guides find that cloud rises from the valleys earlier in the day than in autumn. If you sleep in, you can miss Machhapuchhre completely. Leave High Camp before dawn and you'll usually get a clear sunrise, then enjoy the flowers on the way down.

Many websites tell you to avoid winter. We don't. December is one of the clearest months of the year on Mardi Himal, and you'll have the ridge almost to yourself. January brings snow on the upper ridge, which is beautiful and usually still passable with microspikes.
February is different. It usually brings the heaviest snow of the year, and after a big snowfall the steep section from High Camp to the Upper Viewpoint is the first part to become unsafe. Our guides wait, or turn back at a lower viewpoint, rather than push. If February is your only option, keep a spare day.
Nepal's monsoon normally runs from about 13 June to 23 September and brings around 80% of the country's yearly rain in roughly 105 days, according to the Department of Hydrology and Meteorology. On Mardi Himal that means rain most days, slippery stone steps, and leeches in the forest after rain.
We'll be straight with you: the leeches are bad. If they would ruin your trip, don't come in monsoon. But the ridge can surprise you. Some mornings High Camp sits above the cloud and clears completely, and you'll share it with almost nobody.

On Mardi Himal, when in the day you reach the Viewpoint matters as much as which month you choose. In every season, cloud tends to rise out of the valleys as the day warms up. It comes earliest in April and May, latest from October to December.
That's why our guides leave High Camp (3,580m) around 4:00–4:30am to reach the Upper Viewpoint (4,200m) for sunrise. A few things we've learned:
Snow is most likely to cause trouble in February, is common in January, and is possible in late December and early March. Our guides decide each morning, based on fresh snow, ice, and wind.
| What the ridge is like | What usually happens |
|---|---|
| Frost or light snow | The Viewpoint is usually reachable with microspikes and poles |
| Fresh heavy snow | We wait at High Camp, or stop at a lower viewpoint until the trail is safe |
| A storm in progress | We stay at High Camp or descend; we don't go up |
Mardi Himal is trekked by many Nepali trekkers as well as visitors from abroad, so Nepal's own holidays decide the busiest weeks.
| Holiday | Dates | What it means on the trail |
|---|---|---|
| Dashain | 11–25 October 2026 (main Tika 21 October) | The busiest weeks of the year; buses from Kathmandu fill up |
| Tihar | 7–11 November 2026 | Busy, especially over the weekend |
| Nepali New Year | 14 April 2027 | A busy long weekend in spring |
| Saturdays | Every week | Day hikers from Pokhara on the lower trail |
In 2027, Dashain and Tihar fall earlier in October, so the autumn crowds arrive earlier too.
You can't simply turn up and pick a lodge at the busy camps anymore. Lodges are assigned in advance: a local community system places trekkers who walk without a guide in specific teahouses to spread the crowd, and trekking companies book rooms for their guided groups. In October, November, and April, book early.
The best months are the same, October, November, and April, but these are exactly the weeks when everyone else has holidays too.
Weather tables can't tell you these things. They come from walking Mardi Himal in every season.
On February snow: "When there's heavy snow, usually in February, the climb from High Camp to the Viewpoint is the first part that becomes unsafe. We wait or turn back. That's why I tell February trekkers to keep a spare day."
On spring cloud: "Around April and May the clouds close in early. But it's spring, so the rhododendrons make up for it. Leave High Camp early, get the sunrise, then enjoy the forest on the way down."
On monsoon: "In monsoon the leeches are really bad when it rains. I've experienced it myself. If you're afraid of leeches, don't do Mardi Himal in monsoon. But yes, High Camp can still clear on some mornings."
On the road out: "In monsoon, the first hour of road from Siding is bad. After that, everything is good."
On teahouses: "People think Mardi closes in winter or monsoon. It doesn't. Only a few teahouses close."

If you've read a few guides, you've probably seen "best time" ranges that don't match: some say mid-February to early June, others say September to mid-December. Most are applying the general Nepal rule of "spring and autumn" to a trek that behaves differently. Mardi Himal reaches High Camp in about two days from Kande and depends on clear mornings on an exposed ridge, so the details shift.
| You may read | What our guides actually see |
|---|---|
| "Spring and autumn are equally good" | Autumn mornings are clearer; spring cloud arrives earlier, but you get the rhododendrons |
| "Avoid winter" | December is one of the clearest, quietest months; February is the one to be careful with |
| "There are no views in monsoon" | The ridge does clear on some mornings; the real problems are leeches and slippery trail |
| "Mardi Himal is never crowded" | True most of the year, but Dashain and Tihar fill the lodges |
| "Teahouses close in winter" | Most stay open; only a few close |
Yes. December is clear, dry, and quiet, and one of the best months for views. Nights at High Camp are well below freezing, and snow becomes more likely in the second half of the month, so bring warm layers and microspikes.
Yes, if you start early. Clouds usually close the view by mid-morning in April and May, but leaving High Camp before dawn gets you to the Viewpoint for sunrise, and the rhododendron forest makes the walk down worth it.
Fit beginners can in December or January, with a guide and proper cold-weather gear. For a first trek, late October or early November is the easiest time.
It's shorter, about five days on the trail compared with around ten, but it climbs faster, reaching High Camp at 3,580m on the third day, and the descent is steep on the knees. We rate it moderate and suitable for fit first-time trekkers in autumn or spring.
From Pokhara, fast trekkers can in good weather, but it leaves no time to wait out a cloudy morning at High Camp. Our 9-day trip includes five days on the trail, which gives you that buffer.
We see trekkers without guides on the trail, and lodges for them are assigned through the local community system. A guide makes the most difference in winter snow and when deciding whether the Viewpoint is safe.
Go in October or November for the clearest views, December for clear skies with almost no crowds, and April for rhododendrons. Avoid February unless you can keep a spare day for snow, and avoid June to August if leeches would spoil your trip. Whatever month you pick, the view belongs to whoever leaves High Camp before dawn.
Majestic Trails Nepal runs the 9-day Mardi Himal Trek all year with a licensed guide who checks the weather each evening at High Camp, books your lodges in advance, and knows when to wait out a cloudy morning. Send us your dates on WhatsApp (+977 9700937981) and Bibek will tell you honestly what that week usually looks like on the ridge.
