Where Surfline is the right choice
Surfline's live cam network is a real moat. For any break they cover, you can watch the surf right now — period, wind, sets — before you decide to paddle out or drive further. This alone is worth a Premium subscription for a lot of surfers, especially in crowded urban breaks where conditions turn on and off faster than a forecast updates.
Surfline also has a massive team of forecasters producing regional narrative forecasts, deep archival footage, and editorial surf content. If you want context for why a swell is arriving (storm system, storm track, peak arrival time), Surfline's human-written forecasts are unmatched.
Where LazySurfer is the right choice
LazySurfer solves a different problem: "is the current surf the kind of surf I personally like?" Surfline's 1-5 star rating reflects average opinion across all surfers at a break. But a 3-star day for the average surfer can be a 9-star day for you — depending on your board, style, crowd tolerance, and wind preferences. LazySurfer's model learns from your logged sessions and predicts the rating you would give.

LazySurfer also pulls data directly from NOAA's National Data Buoy Center and National Weather Service stations — for example, NDBC station 46232 (Point Loma South, San Diego) or NDBC station 46042 (Monterey Bay, CA). The raw data in LazySurfer is the same as what NOAA publishes — no intermediation, no proprietary smoothing. The NOAA Buoy Basics post covers how to read this data yourself.
And LazySurfer is offline-first. Session logging works without a signal (common at remote breaks), and the ML model runs on-device so predictions are instant. The free tier has no ads and no time limits. At $49.99/year, Pro is roughly half of Surfline Premium's annual price.
Can you use both?
Yes — and many dedicated surfers do. Surfline for cams and editorial, LazySurfer for personalized timing at spots you know well. The two apps cover different use cases, not directly competing ones. The question isn't "which one replaces the other" — it's whether live cams are worth Premium pricing for your particular breaks.
Verdict
If your home break has a Surfline cam and you value seeing the surf before driving, Surfline earns its subscription. If you log your sessions, surf at breaks Surfline doesn't cam, or want a lower-cost forecast that learns your preferences, LazySurfer is the better choice. Many surfers keep Surfline for cams on free-tier and use LazySurfer Pro for personalization, bringing total annual cost below Surfline Premium alone.
