Attire at Asilomar and the Weather
First, this is an INFORMAL conference. Many people will wear blue jeans! You will want to dress in layers (think vests, fleece jackets, etc.) because coastal fog will make it COLD. The facility is a campus so you will be walking OUTDOORS and you will want to dress appropriately to stay warm. It will feel COLD at some point, bring warm clothes!
During breaks and on the Sunday free afternoon you will want to have comfortable walking shoes to explore the beach (just across the road!), visit the Monterey Bay Aquarium, or for the intrepid join a group to go kayaking on the Monterey Bay (wet suit comes with kayak rental!)
