Summary
Forecast for the next 7 days according to Reefranger:
Today at Julian Rocks, conditions are marginal for snorkeling and diving due to high swells of 2.8m and strong winds at 34.6 km/h creating significant surface chop. As the week progresses, conditions improve, with Saturday and Sunday being the best days for underwater activities. Swells reduce to 2.1m on Saturday and 1.6m on Sunday with manageable winds of 16.2 km/h and 18.4 km/h, respectively. Ocean temperatures are comfortable at 25°C, so a short wetsuit should suffice. Avoid Tuesday due to rising swells up to 2.7m and stronger winds. Prioritize safety and enjoy the vibrant marine life at its best on calmer days.

Diving Forecast
These are the reefranger ratings for the next 7 days. Ratings are available for the morning, low tide, and high tide. Tides are shown during the daytime (6am to 8pm). Ratings currently take into account Swell Height, Swell Direction, and location exposure based on swell direction versus the orientation of the site.
Scores reflect the ocean conditions in the 2 hours between 8am and 10am, and consider local heavy rainfall in the period prior.

Model
Swell and wind impact diving suitability, but not all swells and winds are equal. A dive site may be protected from wind and swell by nearby geography. The model uses these exposure ratings to determine how much impact a wind and swell will have on the dive site, based on the origin of the winds or waves.
