Weather is extremely important to sailors, boaters and weekend yacht enthusiast. Knowing what the conditions are is important before you head out on the water. I recently counted almost 3000 weather related app in the iTunes App Store. Sorting out which ones are the best depends on the boaters need.
There is a ton of weather data out there for free so don't pay for weather or a weather app for your iPhone or smartphone. My criteria for a good weather app would have to include forecast for temp and wind, wave and sea state conditions and radar and satellite maps. Of course you have to have a cell or Internet connection to get the most up to date information. Some of my favorites are listed below.
Weather Channel App (free)
The Weather Channel is hard to beat. They have a great app that has all the data you will need. We have all come to know and love the Weather Channel girls. The have been on cable TV for as long as most of us can remember.
hourly, 36 hour and 10 day forecasts
Weather+ HD App (free)
Weather+ HD displays all information on one display which makes it more for a desktop display. The font for the forecast data is kind of small otherwise a nice looking app.
Five day forecast
National Weather Service (free)
This is not an app but these are screen shots from the NWS site (http://forecast.weather.gov/) accessed through the Safari browser. You can make a home screen icon of your location and add it for easy access by going to the site, selecting the arrow button on the bottom of the screen, instead of adding a bookmark, select add to home screen instead. This will create a icon shortcut on your home screen of your iPhone, iPad or iPod touch. The national weather service is my main source for weather. They provide free weather and are the source for most other weather site on the Internet.
