      score: 0
      out of: 25
      explanation: Too small: 0.5m is below minimum 6.1m. Waves will be weak/mushy.
    swell period:
      score: 7
      out of: 25
      explanation: Moderate period: 15s meets minimum 14s but below ideal 20s. Some groundswell energy present.
    wind:
      score: 0
      out of: 25
      explanation: Onshore/cross-shore: 29 km/h from 77° (ENE). Destroying wave quality. Offshore range: 135°-225°.
  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: -10
      windswell degraded: true
      explanation: -10 points: Short-period windswell is present, creating choppy, disorganized conditions.
    secondary swell bonus:
      adjustment: 0
      explanation: No secondary swell bonus.
  summary: Poor conditions at Jaws. Either swell direction (66°), size (0.5m), or wind (29 km/h from 77°) is unfavorable. Consider other spots or wait for better conditions.
