Typhoon Chaba #15 2010 Report
Surfline and Buoy Weather predicted the swell to come from 217º + - 10º. Which was pretty accurate as the map shows the swell was heading NE at 230º. At this angle Tokyo Bay is completely shadowed by IZU and Mera / Heisaura are 100% shadowed by Ogasawara island. Sean Collins the head forecaster at Surfline says that swells of medium period (10 - 14 seconds) have little propensity to bend around islands and underwater bathymetry.
1. Chaba started losing strength from Thursday 28th in the morning and sped up.
2. Chaba's winds were only driving swell at an angle to get into Tokyo for 18 hours on the 27th all the rest of it was angled to hit Izu and or ogasawara island.
Summary: For a big typhoon this turned into a non-event for Tokyo area surfers. Southern Japan seems to have gotten it good and Ibaraki will get nice back kicked swell as it passes.
