On the new Surfline, we no longer display surf heights on the regional forecast pages. The reason for this is because the data that you see on the regional forecast page is generated by our models for a single point within a region, and the surf height can vary significantly for different spots in a region due to many local factors. Therefore, we want to avoid applying the forecasted surf height for one spot to all spots within a region.
However, you can still access the forecasted surf height for any surf spot on Surfline by going to the spot forecast page. Navigate to the spot forecast page from any spot report page, scroll down a bit and look for the surf height graph:
