We've now got a clear idea of what's happening and who stands to benefit.

Why, if there are a million coral reefs, is there only one Teahupo'o?

Tom Shand investigates.

Today's unexpected high point will be followed by three days of short-range swell and southerly wind.

Warming in the upper atmopshere could affect our swell climate into August.

More swell, bigger rips, bigger rip bowls.

And why is it good for your surfing? (Hint: If you're on the East Coast, you've been drinking from the trough block all week)

It's code for 'it's gonna be big'.

A possible record-breaking high pressure system will produce unseasonal swells.

It topped out at ten metres, the biggest swell in over two years, and it broke under light winds.

The fetch will produce a swinging uppercut on top of an active sea state.
