If coastal kayaking is part of your vacation plans, here’s a site to bookmark – www.saltwatertides.com. It’s a coast-to-coast tide calculator that offers more than 200 places in California, including Monterey Bay (below).
Simply check the coastal area of interest, scroll down to select the month and date and how many days you want to include around that date, and click to find high-low tide times, height of tides, and sunrise-sunset times. It’s very useful. On a semi-related note, check out my post on Dreamflows, another good water data resource. It's primarily for river kayaking.
If you’re looking for kayak launch points in the Bay Area and beyond, try www.gotoes.org. The first thing you’ll probably notice is a link to sewing machine manuals. Huh? Never mind, just go on to “Kayak and Canoe Watertrails.” And note that this is a wiki site – information is submitted by anyone who cares to post, and accuracy can’t be assured. So before you go, always look for corroborating sources, such as “Paddling Northern California” and the “Guide to Sea Kayaking Central & Northern California." See my post on these fine, hard-copy guides. California sea kayaking, kayaker trips river paddling
