Clothing on the Summit

What to Wear

The temperature is 8 to 10°C lower at the summit than at the base.

Sensitivity to the temperature differs from person to person. So if you are unsure about what to wear, take a jacket with you so that you can easily adjust the number of layers as the weather changes.

  • Spring
    (April to June)

    Bring a compact down jacket that you can wear over your clothing. Ideally, also bring a windbreaker to be prepared for the sudden changes in springtime weather. Keep them somewhere that is easily accessible so you can put them on or off quickly. Some days may feel cold in a light spring coat.

  • Summer
    (July to September)

    Some days will feel hot even in short-sleeves, but bring a light layer like a cardigan as it can get chilly in the evening.

  • Fall
    (October to December)

    It is relatively warm during the daytime but gets cold in the evening, so bring a compact down jacket, etc. You will feel comfortable wearing the same type of clothing as during the spring season.

  • Winter
    (January to March)

    The temperature occasionally drops below 0ºC (32ºF) so a down jacket or a thick coat is a must. Ski clothing is a good choice to help you stay comfortable. Earflaps, scarves and gloves are also definitely needed. Bring snow boots for extra comfort.

Does it get colder when the wind is blowing?

Generally, “the wind chill factor causes a drop of 1°C in temperature per 1m/s wind speed” when the wind is blowing. The wind chill factor can be roughly calculated by subtracting wind speed from temperature (this becomes especially accurate in winter). Our website provides wind speed and temperature, updated three times a day (9:00,12:00,15:00). Please check our website to get tips on what to wear when going out.
