The ocean forecast for the Port-to-Pub swim remains for strong northward flow on Saturday, persisting throughout the day. This strong cross current will increase the swim times for all swimmers by about 15 minutes for the fastest to up to an hour for the slower swimmers. In order to stay close to the buoys but not get swept north of Rottnest we advise heading almost westward at the start and then gradually increasing your southward heading as you approach Rottnest Island and the current becomes stronger. Your best heading will depend on your swimming speed and the swim-optimizer can help you with that. The good news is that the Bureau of Meteorology is forecasting weak winds from the east so the sea chop should not affect your swim time. Of course, our advice is based on forecasts which may turn out to be different on the day so all swimmers are advised to adjust their plan to the conditions on the day. Good luck to all swimmers from the OceanCurrent team!
