@SailorElliot being a new sailor means you need to consider the skill development to enable you to survive on the open waters you plan to sail. As Rome was not built in a day, neither will your weather and water skills come instantly from an app.
Here is a "good" NOAA site. It is called Now Coast.
nowCOAST™: NOAA's Web Mapping Portal to Real-Time Coastal Observations, Forecasts, and Warnings
The raw data is presented in a user friendly format to assist the boat owner to understand what the weather forecasters consider important.
Windy is another excellent tool. I use it all the time for looking at the NOAA weather information in again a user friendly format.
Even with these tools, as with the gear on your boat to trim sails, the user (skipper) needs to be able to interpret the information and reconcile it with their boat skills.
You can be the boat owner that ventures out into all sorts of conditions and learns to survive or not whatever Mother Nature throws at you.
Or you can choose to learn to forecast your own weather. Then you take your boat out and adventure a little to see if your forecasting provides the same conditions you experience.
I suggest plan two is just as adventurous but safer. At some point if you keep doing this you'll be able to wake in the AM, look at the water and decide "Today" would be a fun time to take the boat out, or NOT.
