  breakdown:
    swell direction:
      score: 18
      out of: 25
      explanation: Moderate alignment: Swell from 0° is 10° off optimal 350°, workable but not ideal.
    swell size:
      score: 0
      out of: 25
      explanation: Too small: 0.0m is below minimum 1.5m. Waves will be weak/mushy.
    swell period:
      score: 4
      out of: 25
      explanation: Short period: 11s is below minimum 12s. Windswell-dominated (choppy, weak waves).
    wind:
      score: 0
      out of: 25
      explanation: Onshore/cross-shore: 25 km/h from 15° (NNE). Destroying wave quality. Offshore range: 150°-220°.
  adjustments:
    wind history:
      adjustment: -21
      groomed: false
      morning sickness: true
      explanation: -21 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 El Hierro (The Bubble). Either swell direction (0°), size (0.0m), or wind (25 km/h from 15°) is unfavorable. Consider other spots or wait for better conditions.
