So my interpretation is; the crappy weekend forecast is just misinformation from the hack, and it's actualy going to be nuking.

I feel better already.

I believe "pwned" is the correct term.

I think the hacker was actually someone from the Mandurah Mob who wanted to keep others away from their super flat water.

The forecasts last week showed very ordinary wind for the Mandurah estuary, and the Mandurah wind graph supported that.
A lot of us from Perth did not make the trip to Mandurah on that basis, while the locals (and others who did take the chance) were making record runs in the strong wind, day after day.
