The week begins with a fading south-southeast swell, dropping from 2m Thursday dawn to 1-1.5m under glassy-to-moderate north-northeast wind. A fresh northeast/east-southeast pulse builds Friday to 2m by evening under strong-to-blown-out east-northeast wind, then eases Saturday under blown-out northeast wind. Sunday sees a rising southeast swell to 2.5m under strong east-northeast wind before a powerful south-southeast swell arrives Monday, building to 4-5m under strong east-northeast wind. This peaks Tuesday with a dangerous 5-8m south-southeast swell at 16-18 seconds under strong-to-blown-out north-northeast-to-north wind, then peaks Wednesday at WEEK PEAK with an extreme 9m east-southeast swell at 12-18 seconds under blown-out north-to-northeast wind before

About Chiba

Chiba is the closest stretch of Pacific surf to Tokyo, 60 to 100 km east of the city on the Bōsō Peninsula. The coast splits in two. North Chiba runs along Kujukuri Beach, 60 km of straight east-facing sand and the country’s second-longest beach. Tsurigasaki, also called Shida, sits at its southern end in Ichinomiya and hosted the inaugural Olympic surfing event in 2021, where Italo Ferreira and Carissa Moore won gold. South Chiba turns reefier through Onjuku, Kamogawa, Maebara, and Hebara. The Bonsoy Chiba Ichinomiya Open runs at Shida every year on the WSL QS.

Late August through late October is peak, when Pacific typhoons fire east to south-east swell at the coast. Typhoon pulses run shoulder-high to 2 m with mid-period energy. Winter brings shorter north-east wind swell from North Pacific lows, scrappier but punchy at the Kujukuri piers, where locals surf through cold mornings. North-westerlies are the offshore and groom the coast clean.

Water sits warmer than the latitude suggests because the Kuroshio Current sweeps north past the peninsula. Summer is boardies; spring and autumn a 3/2; winter a 4/3 with booties. Crowds are the main hazard. A few hundred Tokyo surfers turn out for any quality day, and Shida is the busiest stretch in the country. Weekday dawn is the only time you’ll find space. On a small day, push down to Taito at the south end of Shida, where longboards take over, or further south to the longboard bay at Ubara.
