In northeast Greenland in April you can experience all manner of arctic winter conditions and as Iceman Polar participants, you must be suitably experienced and equipped to deal with such conditions.
Conditions can vary from perfectly calm days with clear skies and daytime temperatures rising to -5°C to extreme blizzards and whiteout conditions with night time temperatures of -30°C (not accounting for further wind chill). Average day and night time temperatures are around -15°C to -20°C. Several hours dusk/darkness will be experienced between the hours of approximately 11pm and 5am.
Camping will be in full Arctic winter conditions throughout the event and weather in Greenland can change rapidly. Tents should always be pitched and secured in a safe manner as if an extreme storm was expected at any time. Strong and sufficiently high snow walls should be built to protect camp sites from the effects of storm-force winds, taking into account possible wind direction changes. You will be given full training in these methods on arrival in Greenland.
