Conditions at Macaronis in May
May: The Trade-Wind Engine Fires Up
May is when Macaronis starts to crank. Average swell height rises to 4.9ft (1.5m) and the period reaches 13.9s, so the Southern Ocean is already sending serious groundswell. SSW dominates at 65%, with S at 20% and SW at 12%; the 5-6ft (1.5-2m) range grows substantially, and a few 6-8ft (2-2.5m) sets show up from the SSW and S. Ideal wind jumps to 54%, with the SE trade flow becoming much more prominent: SE (17%), SSE (10%) and ESE (10%) combine with a healthy NNE/NE/ENE component to groom the reef. The ocean remains warm at 30.1°C, air temps average 28.4°C, and rainfall drops to 5.7mm/day. Expect more glassy mornings, more consistent swell, and a far more photogenic Macaronis.
