As of the latest buoy reading (2026-08-26 09:56 UTC), 18th Street is marginal: the live 0–2 ft medium-period swell from the E is off its ideal SE direction and is under its usual size, and the wind is light from the S.
Is 18th Street good for beginners?

What's the best tide for 18th Street?
18th Street tends to be best on a high incoming tide — the tide stage LazySurfer surfers have rated highest here. Tide changes how the swell breaks, so check the two-day tide chart on this page for today's high and low times.
What swell direction is best for 18th Street?
The best swell direction for 18th Street is from the southeast (SE). Swell arriving from the southeast lines up best with how this break faces, which is when LazySurfer surfers have rated it highest.
What's the best wind for 18th Street?
18th Street is most often good when it's glassy, with little to no wind — the conditions LazySurfer surfers have rated highest here. Light or offshore wind keeps the wave face clean; check the live report on this page for current wind.
Where does LazySurfer's surf data for 18th Street come from?
LazySurfer reads public data directly from NOAA's National Data Buoy Center and the National Weather Service — the nearest NDBC wave buoy (station 41112) and the nearest NOAA tide station (MAYPORT (BAR PILOT DOCK)). The same raw readings NOAA publishes, with no proprietary smoothing.
Does LazySurfer predict whether 18th Street is good for me?
Yes. LazySurfer trains a custom deep-learning model — a PyTorch neural network with per-user embeddings, retrained weekly on real logged surf sessions from the LazySurfer community — to predict the 1-to-5 star rating you personally would give, rather than a single average rating for everyone.
