There is no racing in the America's Cup in San Francisco Bay on Sunday because of the weather.
Steady rain was falling earlier in San Francisco for the first time in the regatta.
Wind reports indicated a strength of 13 - 16 knots, but the breeze was still too far south to start a race before the latest possible time of 9.40am (New Zealand time).
The race course is set up for the bay's westerly sea breeze.
Regatta director Iain Murray said the race was far too important to have a skewed racecourse.
AAP reports the America's Cup official Twitter account said the wind was not far west enough for a good course, but conditions on Monday (NZT) look very good.
Emirates Team New Zealand needs one more win to clinch the Cup and Oracle Team USA needs six.
The longest America's Cup series was in Auckland in 2003, when Alinghi took 16 days to beat Team New Zealand 5-0. San Francisco is one day short of this.
Waterfront venues in Auckland were full on Sunday morning. Hundreds of fans lined up early outside the doors of Shed 10 to get a prime viewing position in front of the large screens.
The crowd spilled over to the Cloud next door.
Afterwards, many said they would be back on Monday.
The clubrooms at the Royal New Zealand Yacht Squadron were packed and so was the Royal Port Nicholson Yacht Club in Wellington. Chief executive Dean Stanley said the waiting has been nerve-wracking.
