At a Glance: Nepal's Trekking Seasons

• High Season (Best Time): October to November (Post-monsoon) and March to April (Pre-monsoon). Stable weather, clear skies, and ideal temperatures.

• Shoulder Seasons: September (end of monsoon) & May (beginning of monsoon). Good conditions with a higher chance of rain or heat.

• Low Season (Monsoon): June to August. Heavy rainfall, leeches, and obscured views, but lush landscapes and no crowds.

• Winter Season: December to February. Very cold, especially at high altitude, but offers stunning, crisp days and solitude.

Month-by-Month Breakdown for Trekking in Nepal

January & February: The Winter Challenge

• Weather: Days are often surprisingly clear and sunny, but temperatures are bitterly cold, especially at night. Higher passes (like Thorong La on the Annapurna Circuit) can be treacherous and are often closed due to snow.

• Pros: Solitude, incredibly clear air, stunning photography conditions.

• Cons: Extreme cold, many teahouses closed, some high routes inaccessible.

• Best For: Experienced trekkers prepared for cold weather. Lower altitude treks like Ghorepani Poon Hill are viable options.

• Not For: First-time trekkers or those attempting high-altitude treks like EBC.

March to April: Spring Bloom (Pre-Monsoon)

• Weather: This is one of the two best times to trek in Nepal. Days are warm, and the skies are generally clear. The rhododendron forests are in full, spectacular bloom, adding incredible color to trails in the Annapurna region.

• Pros: Excellent weather, warm temperatures, beautiful flora, good visibility.

• Cons: Popular trails start to get busy towards the end of April.

• Best For: Everyone! This is a perfect window for all treks, from Everest Base Camp to the Annapurna Sanctuary.

May: The Shoulder Month

• Weather: The beginning of the monsoon. Days start hot and humid, with a increasing chance of afternoon thunderstorms. Mornings are usually clear.

• Pros: Still good trekking conditions early in the month, fewer crowds than April.

• Cons: Heat, humidity, and the onset of rain. Views can become hazy.

• Best For: Trekking early in the month or in higher, rain-shadow areas like Upper Mustang.

June to August: Monsoon Season

• Weather: Characterized by heavy, persistent rainfall. Landslides can occur, and trails can be muddy and leech-infused. Clouds consistently obscure mountain views.

• Pros: The mountains are incredibly lush and green. You will have the trails completely to yourself.

• Cons: Rain, leeches, mud, flight delays/cancellations to Lukla, and poor visibility.

• Best For: Trekking in the Himalayan rain shadows (e.g., Upper Mustang or Dolpo), which are protected from the monsoon.

• Not For: Classic treks like EBC or Annapurna.

September: End of the Monsoon

• Weather: A transitional month. The rain tapers off, but the skies can still be hazy. By the end of the month, conditions rapidly improve towards the perfect October weather.

• Pros: A great "shoulder season" option with fewer crowds than October.

• Cons: Some residual rain and haze possible, especially in early September.

• Best For: Trekkers looking to avoid the peak season crowds.

October to November: Autumn Excellence (Post-Monsoon)

• Weather: This is the prime trekking season in Nepal. The monsoon has cleared the air, leaving stunningly clear skies, stable weather, moderate daytime temperatures, and cold nights. Visibility is at its absolute peak.

• Pros: The best possible mountain views, festive atmosphere, and ideal trekking conditions.

• Cons: Extremely crowded trails and teahouses. Prices are at their peak. Book flights and lodges well in advance.

• Best For: Every trekker and every major trek. This is the gold standard for trekking in Nepal.

December: Early Winter

• Weather: A return to cold winter conditions. Similar to January/February, but often slightly milder at the start of the month. Days are often clear and sunny, but nights are freezing.

• Pros: Clear skies and far fewer crowds than November.

• Cons: Very cold temperatures, especially at high altitude.

• Best For: Lower altitude treks or experienced trekkers prepared for the cold.
