The wind, the rain and the history.
Wellington's weather has been at its wintry best during the past week, which should play in to the hands of the Junior All Whites who will be more adept to the chilly conditions when they meet Myanmar in their pivotal Group A clash tomorrow at the Fifa Under-20 World Cup.
Myanmar's squad all play domestically and the temperature in the country fluctuates between 22 and 27 degrees during the year.
Having the weather on your side certainly won't win you a game but it could be a useful leg up as New Zealand search for their first win at an Under-20 World Cup. Their previous 11 matches, including the ongoing event, have yielded eight losses and three draws.
Victory over Myanmar, who have opened the tournament with defeats to the US and Ukraine, could push the Junior All Whites through to the round of 16 given four third-placed teams escape pool play, alongside the top two sides from each group.
