Surfnerd forecast for Lafitenia, with wind and swell arrows and hourly conditions.
Example forecast in Surfnerd.

How Surfnerd works

  1. Find your spots.

    Search for a surf spot or browse the map. Watch a spot to see its upcoming surf windows in your Timeline.

    Public forecasts do not require an account. Saving and watching spots require an account. Free includes one watched spot in your Timeline.

  2. Choose a time to surf.

    Check your Timeline, then open a day and hour that fit your schedule.

    Free covers five days. Plus or a trial extends the forecast to 15 days and shows multiple watched spots in your Timeline.

  3. Check the local conditions.

    Check swell, wind, tide, and the spot guide. Map arrows show wind and swell directions against the coast. Model agreement shows how closely the models agree, not the chance of good surf.

    Model agreement, individual model comparison, satellite maps, and advanced swell detail have Plus or trial access limits.

  4. Make the call.

    Choose the spot and time that fit your ability and schedule. Wait if no suitable window is available.

  5. Record the result.

    Save your session and rate the conditions. Adding or editing a session on the website or in the iOS app can update shared spot rules used in future surf quality ratings.

    Updating these rules requires an account and a session linked to forecast data. These rules are shared for the spot; they do not learn your personal preferences.

Choosing a surf forecast app or website

What is the best free surf forecast app for my spot?

Start with a free forecast that covers your spot. Surfnerd Free includes five forecast days and one watched spot in your Timeline. Surf Captain offers five days with ads. Check the free limits for the features you need: a free download does not mean every feature is free.

Compare forecast ranges and access limits

Can I use a surf forecast website without an app?

All eight products in this comparison have a website. Native app support varies. Surfnerd has an iOS app, and its website also works in a browser on Android or a computer. You can open Surfnerd’s public forecasts without an account; saving and watching spots require one.

Which surf forecast is most accurate?

This comparison does not establish an accuracy winner. Check forecasts for the same spot, time, and number of days ahead, then compare them with observed conditions. Model agreement, surf quality ratings, human reports, and camera images each tell you something different.

Present

Worldwide catalog of public surf spots, with private custom locations. The current number of public spots was not counted in this implementation review.

SN1

Present

Global catalog with thousands of named surf locations. Surf, camera, and human-report coverage are different totals; exact current counts need confirmation.

SL5

Present

Worldwide forecast points and regional high-resolution models. Named surfing points are a subset; a current surf-spot count was not established.

W4

Present

International forecast locations with strongest report/camera coverage in Australia. Earlier global expansion and spot totals need independent confirmation.

SW2

Present

USA, Canada, Caribbean, and Central America are listed, including Great Lakes. No official current total was established.

SC3

F1F3

Present

Company reports over 7,000 surf breaks worldwide. Camera, observation, and guide coverage vary.

S1
Forecast location detail

Is the forecast for a region, a break, or an arbitrary point?

Present

Forecasts use coordinates and the named spot’s swell, wind, depth, and tide rules. Input model grids are distinct from the scale of an individual breaking wave.

SN1SN2

Present

Named-break forecasts use local wave modelling. Custom ocean points provide a different, offshore forecast product.

SL6SL3

Present

Forecasts refer to model points. A surf POI adds location information but does not establish a breaking-wave model for that break.

W5W4

Present

Named coastal locations; forecasts can distinguish differently exposed beaches within a region. A location name need not mean one individual break.

SW3

Present

Forecasts apply to a local region, not each individual surf break. The user applies knowledge of their specific spot.

SC1

Present

Model data is interpolated for a point. CS+ can shift coastal wind sampling offshore; this is not a break model.

G11

Present

Named points receive model forecasts. A break-specific transformation using reef, bottom, or shelter data was not established.

S11S9
Surf quality assessment

What does the surf rating mean, and which conditions affect it?

Present

Spot rules assess wind, wave energy, swell interaction, and tide. Ratings describe expected suitability; they are not observed surf or a personal safety decision.

SN2

Present

Hourly ratings distinguish model output from human assessment. Most basic ratings use surf height and wind; local tuning varies.

SL4

Partial

Surf POI stars indicate popularity from searches, not forecast surf quality. A separate break-quality prediction remains unconfirmed.

W4

Present

Observed reports can carry a rating out of 10 and surface description. A future hourly quality rating at every location was not established.

Sources and review notes

All assessments use the same capability definitions. “Unconfirmed” does not mean “No.” A source can document only part of a capability. Prices vary by platform, region, and billing period; use each product’s official access page for current terms.

Model agreement is not a probability of good surf. No common accuracy benchmark or comparative click-count test supports a “more accurate” or “fewer clicks” claim here. Forecasts, sensor readings, human reports, and camera images are different types of evidence.

Some Swellnet pages block automated access. Some Windguru evidence comes from indexed help pages. Windfinder sources disagree on catalog size and model resolution. Surf-forecast.com sources disagree on forecast range and alert access. Paid workflows and full keyboard/screen-reader access were not tested across competitors.

Each reference below links to official product material where available. The review date records when the material was assessed, not its publication date. Some documents and indexed copies are older. Surfnerd entries come from an implementation review; they are not independent accuracy tests.
