[2026.1] Historical Weather Overhaul

Historical Weather Overhaul You surface into a North Atlantic gale because it is November and you are at 55° North - not because a random number said so. This mod rebuilds UBOAT's weather from the real 1939–45 record: the wind, the storms, the rain, the fog, the snow and the cold your boat meets are the ones that region and month actually had, drawn from ERA5 and cross-checked against ICOADS ship observations. This mod gives every sea its own character. It doesn't replace the weather engine, so nothing you love breaks: fronts still build over hours, storms still roll through and pass, and the radio forecast still matches what arrives. It just makes all of it historically true. Fifteen real climate channels - wind, storms, rain, fog, snow, temperature, sea state and more - for every sea and every month of 1939–45. What you'll feel Seas with a memory. The North Sea in winter is brutal, with the odd dead-calm morning. Biscay in high summer is glass. You learn a patrol area's moods the way a real skipper did. Storms that actually come. Gales pass close as often as they historically did - frequent in the winter westerlies, rare in the summer tropics - instead of the broken near-never of stock 2026. 1. Rain where it really fell, thunder where it really formed. Rain follows the real precipitation record, not the cloud cover - drizzle coasts drizzle, dry-summer seas stay dry. Thunder is held to warm, convective waters, so the overcast winter Atlantic no longer rumbles. Snow that belongs to the place. Snow falls where the record shows snow and skips the mild maritime coasts that never saw it - no more January blizzards in the tropics. Fog where fog belongs. The Grand Banks close in every summer, just as they did in 1942. This mod also provides a fix for broken fog detection in vanilla. A living thermocline. Real seasonal water temperature drives the sonic layer - pair it with my Shadow Zone mod and your hiding depth shifts with the season and the current. Winds off the right
