  "question": "When is the best time to charter a yacht or catamaran in Greece?",
  "answer": "The best-value months to charter a catamaran in Greece are January, February and March: €4,527 per week in March against €9,538 in August, in 12 Knots' average asking prices (updated October 2026). The best weather months are June to October, with a mean air temperature of 20–28 °C (our calculation from NASA POWER data at Lefkada); the sweet spots are September (€8,098, 24 °C) and October (€5,414, 20 °C); avoid June, July and August if price matters, the three priciest months (from €8,402).",
