Mera Peak Climbing Weather and Temperature Guide. Mera Peak, standing at 6,476 meters (21,246 feet), is Nepal’s highest trekking peak and a popular objective for climbers. The weather in the Mera Peak region is highly seasonal and a crucial factor for a successful and safe ascent.
The best times to climb Mera Peak are during the spring (March to May) and autumn (September to November) seasons. These periods offer stable weather, clear skies, and favorable climbing conditions.
January
- Weather: This is the coldest month of the year, with extreme cold and dry conditions. While skies can be clear, there is a high risk of heavy snowfall and strong winds, which can lead to blizzards and whiteout conditions.
- Temperature: At higher altitudes, temperatures can drop to -20°C to -25°C (-4°F to -13°F) or lower. Even during the day, temperatures remain well below freezing.
- Conditions: The trails and mountain are covered in deep snow and ice, making the climb technically challenging and dangerous for all but the most experienced and well-equipped winter mountaineers.
February
- Weather: Similar to January, February is still very cold, but the days begin to get slightly longer and clearer toward the end of the month. Heavy snow is still a significant possibility.
- Temperature: Temperatures remain frigid, with nighttime temperatures at the summit often dropping to -20°C (-4°F).
- Conditions: The mountain remains covered in snow and ice. The cold and icy conditions require proper gear and experience. Early February is still deep winter, but late February can be a more viable, albeit still challenging, option.
March
- Weather: This month marks the start of the spring climbing season. The weather becomes more stable with increasingly clear skies and minimal precipitation. However, the first few weeks can still be very cold from the lingering winter.
- Temperature: Daytime temperatures at lower altitudes can range from 0°C to 15°C (32°F to 59°F), while at higher altitudes and at night, temperatures can fall to -10°C to -15°C (14°F to 5°F).
