Conditions at Thunders in June
June: Peak SSW Powerhouse
June is when the Southern Ocean really winds up. Average swell height builds to 1.6m (5.2ft) and the period hits 14.2s, meaning long-period, high-energy waves are arriving on a daily basis. The direction is extremely concentrated - SSW accounts for 67.5% of all swell, with S at 15.8% and SW at 14%. The vast majority of the surf, 57%, is in the 1.5-2m (5-6.5ft) range, and another 9.4% sits at 2-2.5m (6.5-8ft). This is serious, reelable Indo reef surf.
Winds remain favorable. The ideal surfing wind share is 55%, and the trade-wind flow from the ESE/SE/SSE quadrant keeps the surface in check for most of the daylight hours. When the E/ENE offshore directions kick in overnight and into the morning, the lines on Thunders are world-class. With rainfall down to 5.47mm/day, sea temperature at 29.8°C, and air temps around 28°C, the tropical dry season delivers hot, clean days and consistent swell. June should be on everyone's radar if you want power and quality in equal measure.
