Conditions at Impossibles in April
April: The Magic Window Opens
April is a turning point. With the northwest monsoon retreating, ideal offshore wind frequency springs to 70%. The swell no longer relies on the SW quadrant alone-S and SSE directions contribute nearly 20%, while SSW still leads with 65.4%. The average period stretches to 13.8s, pushing the swell into the powerful long-period category, and average height holds at 5.5ft (1.7m). The bulk of energy sits in the 5-6.5ft (1.5-2m) range, with 11.2% of SSW wave faces exceeding 6.5ft (2m). East-southeast trades dominate the wind rose (ESE 32.2%, E 19.8%, SE 13.2%) but at mostly moderate 10-20kph speeds, Impossibles' offshore SW-wind windows are more frequent. The dry season brings sunny skies, just 4.23mm/day of rain, and water temperatures easing to 29.1°C. This is prime time.
