The Aloha Classic is not a PWA-run event, but they have started posting daily live ticker updates on the PWA site.
If you see a link to a live stream on some social media platforms, then watch out that is a scam that is going around, and someone will ask you for money - when the actual live stream will be free.
That IWT livestream will only happen when the competition is on, and this event runs for 12 days, with a licence to run heats on any day but only for five days in total of the waiting period. This five day ruling is so as not to annoy the local surfers by blocking out their wave break.
The lack of information so far is down to the organisers not yet knowing which day they will compete on, and they need waves and some wind. The Windguru forecast (pictured here) shows a 1.6m swell arriving for today, Wednesday, but not much wind. The wind will however be in the E/NE tradewinds direction, so there may be more wind than forecast. it could happen today - and I think they have yet to run the men's trials heats, to determine the final placings for the competition heat ladders.
Windguru then shows a bit more wind for the weekend onwards, but maybe with less swell and/or with the swell in the 'wrong' direction, and so it's a tricky call for head judge Duncan Coombes. It's also a gamble to rely on a forecast that comes in at the end of the waiting period, especially when that forecast is still a week away.
So they probably will start today (Wednesday) if they can, and we may hear that soon, once it's breakfast time or later, on Maui.
If you are reading this in Mainland Europe then Hawaiian time is ten hours behind, whereas in the UK it's an 11 hour time difference - so any action won't happen until mid evening for us, at the earliest. In Australia, you get to watch any live heats from breakfast time, at the earliest, I think.
(If it's 9am on Maui then it's 8pm on the same day for London, or 9pm in Paris - and 3am the following day in Perth. )
