We have used a weather station from Oregon Scientific for several years. I've fitted one of the mounting tubes to the ladder and have a coupling for a snug fit so that it can be stored among the clothes in the hanging locker, when underway.
There is wind direction and strength. Humidity, a Barometer, with a time graph showing trends, temps in and out, a rain gauge ( not often used), atomic time, date, and moon phases, It also offers a forecast based on returns and can be synchronized with the laptop.
After many years at sea we are very comfortable with doing our own forecasting. We did not have such a sophisticated system for the Ketch Imagine, it has been a very useful tool and fun to observe.
