TideGuide

This skill will give the tide report for most locations with a NOAA station along with some popular beaches. If Tide Guide cannot find your location in the NOAA database it will try to find a location within 100 miles of the specified location. It will also allow you to set a default city, state and or country. Some of the supported cities/locations are:

Seattle
Portland
San Francisco
Santa Barbara
Santa Monica
Baltimore
Long Beach
San Juan Island
Los Angeles
Monterey
Ventura
Puget Sound
Vancouver
Portland
Astoria
Honolulu

and many, many more.
