Where can i find relevant swell charts to track any swell that might reach Perth?? Or am i dreaming? 
Thanks in advance for the constructive feedback

If the swell did reach Perth it would make it to Geraldton first and we could tell you guys all about it. 
NW would just increase stuff like "seas". There is too much activity down Antarctica way. There is always tiny pulses of swell coming from the south direction. NW pulse would create washing machine seas.
On a good note there could be some awesome double ups to punt off at hells gates!
Cyclones in WA provide of shore breezes sth of them and only create swell after they have passed you by
