  description: Frigates is Fiji's Coral Coast answer to Cloudbreak—a heavy left-hand barrel that breaks over a mushroom-shaped reef in the remote Kadavu Passage. The wave is powerful and hollow, with a deep takeoff zone and a challenging mushroom section that can double up and throw. The 40-60 minute boat ride from Waidroka Bay keeps crowds minimal, making Frigates one of the least surfed world-class waves in Fiji. When it's on, it delivers the kind of empty barrels you dream about.

      out of: 25
      explanation: Perfect alignment: Swell from 219° is within 5° of optimal 220°.
    swell size:
      score: 3
      out of: 25
      explanation: Too small: 1.0m is below minimum 1.2m. Waves will be weak/mushy.
    swell period:
      score: 23
      out of: 25
      explanation: Good period: 15s is 94% of ideal 16s. Clean, powerful groundswell.
    wind:
      score: 1
      out of: 25
      explanation: Onshore/cross-shore: 26 km/h from 158° (SSE). Destroying wave quality. Offshore range: 60°-135°.
  adjustments:
    wind history:
      adjustment: -10
      groomed: false
      morning sickness: true
      explanation: -10 points: Previous days of onshore wind left residual chop ("morning sickness"), reducing wave quality.
    windswell penalty:
      adjustment: 0
      windswell degraded: false
      explanation: Groundswell-dominant conditions (clean, long-period waves).
    secondary swell bonus:
      adjustment: 0
      explanation: No secondary swell bonus.
  summary: Poor conditions at Frigates. Either swell direction (219°), size (1.0m), or wind (26 km/h from 158°) is unfavorable. Consider other spots or wait for better conditions.
