The forecast comes from elsewhere. The weather is already here.

Reading the weather from natural signs is the practice of working out what the sky is about to do from what it is doing now — the order the clouds arrive in, the way the wind backs or veers, the fall of the barometer, the behaviour of the birds, the set of the swell. For most of maritime history it was the only forecast a sailor had. It is still the only one that requires nothing outside the vessel — no signal, no satellite, no subscription. Once you've learnt the signs by logging, you wont need the app either

VAKA Skywatch is a training application for people who want to understand how it works, and to practice doing it. You log what you see; it weighs the signs the way the old hands did — by strength, by sequence, by the tendency of the barometer — into a plain twenty-four-hour outlook, and shows you which observations drove it. It carries around ninety signs, corrects the textbook North-Atlantic lore for the climate you are actually in — temperate, Mediterranean, trade-wind, inshore or inland, in either hemisphere — and sharpens the more you log. The reasoning is shown at two levels: for those with the seamanship already, and for those starting from nothing.
