On 9th February 1836 the Jersey Argus printed a letter from a passenger recounting his recent experience of sailing on the steam packet paddle steamer Flamer on a voyage from Guernsey to Weymouth in a gale.
This does illustrate the lack of quality weather forecasting at the time as no responsible and experienced master would have set off on a cross Channel voyage on a ship of that size if he had believed in advance that he would be caught out in a gale.
Today a master has a plethora of information on which to base his decisions about sailing or not sailing on account of the weather not only from mainstream sources like the Met Office but also from websites which give predictions of the force and direction of the wind, as well as the predicted wave heights, on an hour by hour basis for any particular location
Of course in 1836 there was none of this. There were storm signal stations around the coast which would hoist a cone by day and three red lights in a triangular shape by night if a gale was thought to be in the offing with the point facing upwards if the wind was from the north and downwards if from the south. However the information on which that was based was a bit hit and miss, was dependent on opinion and folklore rather than absolute fact and you had to be close enough to them to see the signal stations anyway.
In 1836 weather maps as we know them today with isobars and so on were still way in the future. The arrival of the electric telegraph in the late 1830s enabled information to be more readily gathered from distant locations and this gave a better picture of the weather already in another place but heading your way on the wind. The term fronts was not coined in weather forecasting circles until after the First World War when the similarity between cold and warm areas of pressure battling it out with each other and military confrontations in war led to the adoption of the name fronts to help describe what was going on with the weather.
Signal stations were placed on the Channel Islands in the early 18th Century so there would have been this information available to Flamer's master but how accurate it was I don't know. Indeed looking south west from the Channel islands into the prevailing SW winds rolling in from the Atlantic, or indeed winds from any other direction, in 1836 it was just not possible to know what the weather was already like a hundred to two hundred miles plus away from you. With a severe gale sweeping in with wind speeds gusting 50 knots or more, serious weather 100 to 200 miles away when you set off from St Peter Port would be with you in two to four hours, less than the journey time between Guernsey and Weymouth. And so it was with the Flamer.
