"So not that strong...but a nice day for racing."
A northeasterly swell measuring about 1m is forecast as well, but is not expected to be significant or have much impact on the sailing activities.
With temperatures being above normal for many parts of the country, members of the public keen to see the action live tomorrow are being told to be sun smart.
"It's going to be a nice day, so put on some sunblock. I definitely recommend that."
Heading into Saturday, light winds and sea breezes are forecast in Auckland and a similar high of 25C. A low of 17C is expected.
Like tomorrow, the weather is set to be fine on the start of the weekend - save for some areas of morning and evening cloud.
But come Sunday, a period of rain is due in the afternoon.
The MetService also says there is a chance of a shower and northwesterly winds will start to develop.
