The Right Direction Plotting Western Australian swell direction data in 2013

Posted Tuesday 11th June, by Ray


Last month saw some pretty memorable days of surf in and around Perth. The swells weren’t particularly big, but these graphs tell the full story.

We’ve been compiling all swellcast data since January 1st this year. The forecasts are updated every six hours, and the nearest next forecast step (ie. typically the most accurate) is recorded for posterity. With 4 recordings per day, there are 120 per month, give or take. These charts show the ratios of swell direction data by compass bearing, by month.

It’s plain to see that things started to shift more west in May, giving small to medium swells a lot more emphasis. Also worth noting is the prevalence of west swell in January. There was a pretty solid swell event at the start of the year, but not enough to significantly skew the data.

It will be interesting to see the year pan out. We’ll keep this updated each week as more data comes in.
