Conditions at Kealia Beach in April
April: Trades Take Over
April is when the tradewind regime locks in. The average swell height drops to 7ft (2.1m), the period shortens to 10.3s, and the swell rose flips hard to the east: ENE is 25.0%, E is 16.5%, NE is 15.6%. These are wind swell and medium-period pulses generated by the strong Pacific trades, and they hit Kealia's east-facing shore directly. The surf is still very much rideable, with the 5-8ft (1.5-2.5m) range making up a huge chunk of the distribution.
But the same trade machine that creates the swell also ruins the surface. ENE winds blow 44.6% of the time and ideal offshore winds only 7%, so Kealia spends most of April side-on and bumpy. Rain actually decreases to 1.61mm/day, and air temps warm to 23.2°C with water at 24.1°C. If you are not picky, there are still pulsing highs, but the months of clean, glassy Kealia are growing distant.
