Waves are the total wave energy at a given location, which is the sum of the swell and wind waves.
Swell is a series of ocean waves that have traveled a long distance from the source of the wind that generated them. Swell waves are typically longer and more organized than wind waves, and they can travel for thousands of miles.
Swell 1 and Swell 2 are the first and second largest swells, respectively. Swells can come from different directions, so it is possible to have two swells coming from opposite directions at the same time.
In your case, you are saying that the waves and Swell 1 are coming from the west, while Swell 2 is coming from the east. This means that the overall wave energy at your location is coming from the west, but there is a secondary swell coming from the east.
Whether or not it is safe to spend the night at anchor in your location depends on a number of factors, including the size of the swells, the depth of the water, and the type of anchor you are using. If the swells are large and the water is shallow, there is a risk of your boat dragging anchor or being swamped by waves.
If you are unsure whether or not it is safe to spend the night at anchor, it is always best to err on the side of caution and move to a more sheltered location.
