Averages from a year of Skyscribe's weather in typical the open sea. You can set how high, how far from the sea and how far from the equator it lies, and the weather follows.

How it sounds at the table

A few days from that year, as Skyscribe describes them to read to your players. No two days read the same.

Rain has fallen on the ship since before dawn, and the scuppers have not stopped running. The air is mild and soft on the skin, while the rigging hums in a brisk south wind. The casks are full and the decks never dry, and the crew joke that the sea has moved aboard.
Warm voice · Autumn, steady rain
The cloud hangs low over the open sea, and the ship is the only thing in all that gray with any shape to it. The mild day asks nothing of anyone and gives about as much, and a faint northwest breeze touches the face now and then.
Grim voice · Spring, mostly cloudy
Lightning flashes, thunder answers and the rain comes in sheets, and the cook says this is exactly what happens when nobody finishes their porridge. It is the kind of cool day that puts color in every cheek, though every so often a gust from the south catches someone off guard.
Whimsical voice · Spring, thunderstorm

What to watch for

The hazards that come with the open sea. When the weather makes one likely, Skyscribe shows the risk and lets you roll to see whether it strikes.

Rare sights

Keep an eye on the scenery. Now and then something unusual turns up in the picture, and a few sights are rare enough that most players will never see them.
