Today at Nazaré (quick links)

Use this 30‑second routine to check if it’s worth driving up to Praia do Norte:

  • Check significant wave height (Hs) and marine bulletins on IPMA.
  • Use the Windy embed below: toggle Waves, Swell 1, and Wind layers; click offshore from the lighthouse to open the spot card (hourly Hs, period, direction).
  • Open the Praia do Norte / lighthouse webcams to confirm face quality and wind texture.
  • New here? See Where to watch safely ↓ before driving up on XXL days.

Tip: On big-swell mornings, re-check the webcam around sunrise—a small wind shift can make or break conditions.

Quick Travel Planner – Praia do Norte

Plan your Nazaré big‑wave mission in minutes with these trusted partners:

Booking tip: November–February and holiday weekends fill up fast — lock in car + stays early if you’re aiming for a big‑swell window.

For full trip planning (how many days, routes from Lisbon/Porto, what to combine), use the dedicated Nazaré Surf Trip Guide on your site.

Praia do Norte Interactive Forecast (Windy)

Use the interactive Windy map embedded here to see:

  • Offshore wave height (Hs) gradients into Praia do Norte
  • Primary swell (Swell 1) direction and period
  • Wind speed and direction above the headland

Pro move: On the spot card, switch between ECMWF / ICON / GFS to compare runs. ECMWF is often the most consistent for the west Iberian coast, but always cross-check when a swell is borderline.

How to Read the Forecast (2-Minute Guide)

1. Wave height (Hs)  – Background Energy

Think of Hs as your background energy meter: higher Hs = more potential for big faces. Nazaré still needs the right period, direction and wind, but Hs tells you if the day is even worth considering.

  • Rule of thumb: You want Hs clearly above the typical west‑coast baseline on the maps, with a strong height gradient feeding the headland.

2. Period (seconds)  – Stored Power

More seconds = more stored energy and faster deep‑water travel.

  • Starts to matter: ≥14 s
  • Classic big‑wave days: 16–20 s is when the canyon usually “supercharges” incoming swell.
  • Shortcut: 16–20 s + big Hs + good direction = real potential under the lighthouse.

3. Direction  – Canyon Alignment

Direction decides whether the canyon gets “lit up” or not.

  • Sweet spot: W–NW into the canyon axis.
  • Too far N or WSW: The swell can miss the ideal focus onto Praia do Norte, even if numbers look good on paper.

4. Wind – Face Quality

Tide helps refine timing, but canyon focusing > tide here.

  • Best grooming: NE–E (light–moderate) keeps faces clean and lines open for rescue teams.
  • What to avoid: Strong onshore or cross‑onshore W–SW winds that crumble faces and add dangerous chop.

5. Tide – Helpful, but Secondary

Tide helps refine timing, but canyon focusing > tide here.

  • Many big days look best on the push, yet period and direction are far more important than tide alone.

6. Model Reality Check

Forecasts are only as good as the models behind them.

  • On the Windy spot card, compare ECMWF / ICON / GFS.
  • If guidance diverges a lot, treat the day as uncertain and re‑check on the morning of the swell with updated runs and webcams.

One‑liners:

  • Refraction = waves bend as depth changes.
  • Shoaling = waves steepen and grow as water gets shallower.

What Counts as a “Big-Wave Day” at Nazaré?

Use these rule‑of‑thumb thresholds as guides (never guarantees):

  • Period: Ideally 16–20 s (≥14 s can still be impressive).
  • Primary direction: W–NW into the canyon axis.
  • Wind: NE–E or very light winds locally.
  • Map signal: A clear height gradient aiming straight at the Sítio headland on Hs maps.
  • Webcam confirm: A clean, steep face under the lighthouse with minimal cross‑chop and obvious scale.

Example of a classic big‑wave pattern:

  • Hs 5–8 m on the west coast, period 16–19 s, swell WNW, light NE breeze at sunrise.

Set expectations:

Even with perfect numbers, local wind shifts, fog, rain and sandbar changes can flip the script. Always treat thresholds as filters, not promises, and confirm in real time on the webcams before committing to a long drive.

Webcams: Watch Nazaré Waves Live

Before you drive to the lighthouse, check all three cams in this order. Use each for a different decision.

1. Praia do Norte (Lighthouse) — Decision cam

Shows the main peak and bowl under the fort. Use it to judge face quality, peak consistency, and overall scale.
5-second check: are sets standing up in the same place, with spray blowing straight back (offshore) and minimal cross-chop?

Nazare: Nazaré – Leiria, Portogallo: Canhao

2. Nazaré Canyon View — Set detection / wide angle

Wider shot that helps you spot long-period lines marching in and how the canyon line is feeding the headland. Great for seeing if bigger sets are lurking outside when Praia do Norte looks quiet.

3. Praia da Vila (Town/Main Beach) — Wind & visibility sanity check

This angle is handy to confirm local wind, fog, rain, or sea-spray when the lighthouse lens is messy. If Town shows clean offshore while the lighthouse looks smeared, it’s likely spray on the lens, not bad wind.

Nazare: Nazaré – Leiria, Portogallo: Praia da Vila

How to read the cams (what “good” looks like)

  • Defined sets marching in on a consistent peak (not breaking randomly along the bank).
  • Clean faces with little to no cross-chop; lines look straight and groomed.
  • Offshore tell: spray blown straight back from the lip (not sideways).
  • Crowd & ops: tow/rescue craft staged and moving smoothly (often a sign the wind is cooperating).

Red flags (when to skip the mission)

  • Webcam shows messy whitewater everywhere, sideways spray, or low cloud/fog sitting on the headland.
  • Praia da Vila shows clear onshore while Windy suggested offshore → reality wins.

Troubleshooting (common webcam issues)

  • Hazy / smeared view? Salt-spray on the lighthouse lens — refresh, try a different angle, or re-check in 10–15 min.
  • Frozen frame? Browser cached the feed — hard refresh or open the “Open in new tab” links above.
  • Night glare? Wait for first light; long-period swells are easier to judge at sunrise.

Pro Tip

After cams look promising, cross-check the Windy spot card (Waves / Swell 1 / Wind) for the next 2–4 hours. If period 16–20 s and wind NE–E hold through your arrival window, you’ve got a solid chance at a show.

Where to Watch Safely (and Smart)

Watching is free; staying safe is non‑negotiable:

  • Best vantage: Forte de São Miguel Arcanjo (lighthouse) terraces above Praia do Norte.
  • Arrive early: On hyped swells, aim to be up there before ~10:00 — traffic control and temporary closures near the fort are common.
  • Parking & walking: Park legally, expect to walk, and bring layers, water and sturdy shoes for wind and uneven ground.
  • Respect barriers: Never cross fences or tape; give rescue teams plenty of space to operate.
  • Photography tip: A telephoto lens (200mm+) and a soft cloth for salt spray make a huge difference on XXL days.

Getting to the Lighthouse on Big Days

  • From Lisbon (LIS): Around 1 h 30 via A8 to Nazaré, then follow signs for Sítio / Farol / Forte.
  • From Sítio da Nazaré: Follow the road toward the fort; on XXL days, expect slow traffic or restricted access, sometimes pedestrian‑only near the headland.
  • Where to stay to avoid traffic headaches: If wave‑watching is your priority, stay in Sítio da Nazaré so you can walk to the terraces and skip parking stress.
