Conditions at Bondi in January
January: Summer Sea Breeze Sessions
January is classic Bondi summer surf. The dominant swell window shifts away from the Southern Ocean and toward the Tasman Sea, with ENE and E swells accounting for more than a third of the wave energy and ESE/SE/SSE filling in the rest. Average surf heights hover around 5-6ft (1.6m), and the period sits at 8.4s, so most days are punchy and rideable rather than heavy. The S/SSE/SE directions are still present, which is good, but the lack of long-period groundswell means the wave quality is highly dependent on wind. Offshore N/NW flow is scarce at only 10 percent, while onshore S/SSE/SE/ESE seabreezes develop on 37 percent of days, leaving a slim 25 percent ideal-wind window. Water temperature is 22.8°C and air temps average 22.7°C, making summer gear the norm. Rain averages 2.8mm per day, mainly from afternoon heating. Get up early to beat the seabreeze and you'll find clean, fun-size waves at Bondi, but by midday it's often a mushy crumble.
