Ships from opposite sides encountering each other in bad weather was rare, but when they did, they would typically engage. There are two examples of this that come to mind. The first was the hunt for the Bismarck in May 1941. During this, Fleet Air Arm aircraft made a number of sorties against Bismarck despite stormy weather. The carrier Victorious, approaching from the north, managed to launch her strike before the weather closed in, but the aircraft she launched to shadow Bismarck were not so lucky, with four aircraft being lost to bad weather over the next two days. Ark Royal, approaching from the south with Force H, was steering directly into a strong storm. Despite high winds and a very heavy sea (~55-60ft waves), Ark Royal was able to launch and recover a strike which unintentionally attacked the British cruiser Sheffield, fortunately doing no damage. A few hours later, with the same prevailing weather conditions, she launched a strike which successfully attacked Bismarck, crippling her. The next day, the British battleships Rodney and King George V, accompanied by several cruisers and destroyers, closed with and sank Bismarck. The weather had moderated only slightly from that encountered by Ark Royal, with gale-force winds and frequent rain squalls. The other example was the Battle of the North Cape, in December 1943. This pitted the German large cruiser/battlecruiser Scharnhorst against a British force centred on the battleship Duke of York and four cruisers. Fought in an Arctic winter, it was marked by heavy seas, with a prevailing wind of Force 7-8. Scharnhorst had set off with a force of four destroyers, but these had been forced to turn back, in part by the bad weather. The weather had little effect on the outcome of the battle, though the British destroyer Matchless did receive some damage from the waves as she closed to give Scharnhorst the coup-de-grace, preventing her launching her torpedoes. However, had Scharnhorst attempted to turn into the wind, Admiral Bruce Fraser, commanding the British force, felt that he would be unable to give chase, as his ships would be much slower travelling into the heavy seas.

EDIT:

A third action in heavy seas came in April 1940, during the German invasion of Norway. The British battlecruiser Renown encountered Scharnhorst and her sister ship Gneisenau off the Lofoten Islands in Northern Norway on the morning of the 8th April. Storm-force winds and high seas had been present throughout the night, with one of Scharnhorst's fuel tanks flooding through seams opened by a wave. Renown ambushed the German ships, which fled at speed into the waves. Renown was somewhat of a worse sea-boat, so the German ships were able to out-run her. Little damage was done by the fire of either side, with fire control greatly hampered by spray. Both sides took damage or flooding from the seas, with Renown taking some flooding down a hatch blown open by the blast of her guns, one of Gneisenau's turrets partly flooding through a hole opened by a British shell, and Scharnhorst's A turret being put out of action after the electrical motors that powered it were ruined by water entering the turret through the ejection ports for shell casings.

Sweet thanks for the knowledge
