How often is this page updated?
Each location is refreshed every three hours. The hourly view, 7-day forecast, luck factor and packing notes come from the same stored update.
What is the luck factor?
We compare the 7-day forecast with the version-matched historical observations available for the same time of year at Dee Why. The delta shows whether conditions look better, worse or about the same as a typical mid-October.
How is 'best session' picked?
We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer.
Where does the data come from?
Open-Meteo's Marine API (swell height, period, water temperature) and Weather API (wind and conditions).
Does the score capture local knowledge?
Partly. The model uses stored spot geometry, swell ranges and tide preferences where configured. It cannot see changing banks, crowds, access, closures or everything visible on a local cam, so treat it as a starting point.
When is the best time for Surf at Dee Why?
The best week for surf at Dee Why is the week of 2 November (score 3/5) with low crowds.
