During the short summer season, the sea ice, which has formed over the long winter, as well as the ice left from previous winters, melts to a greater or lesser extent. The ice usually retreats from west to east (Pacific to Atlantic). This means that in most years the eastern approaches to the NW Passage are the last to become free of ice. If planning an east to west passage, as in our case, the way to overcome this problem is to plan on arriving at the chosen point of departure in the second half of July, and be prepared to wait until the ice has started retreating to such an extent that a transit may be safely attempted. This tactic can entail a long wait, and also means that yachts must be ready to go as soon as conditions look favourable, as the situation can change rapidly. It is therefore imperative to be in the appropriate area and ready by mid-July at the latest, which is exactly what we are doing by having arrived at Nuuk before the end of June.
