This skill is great for knowing the wave conditions on Lake Michigan in Chicago. It's a handy little tool that helps you decide whether or not to take your boat out for the day. It works by fetching the wave report from the National Weather Service's website.
Once you've set up the skill, you can say "Alexa, get today's wave report" for the current day's report, or "Alexa, get the wave report" to get the full report for the next two days and nights.
