Why did Britain stop the weather forecast during World War II?

Britain stopped the weather forecast during World War II to prevent the weather information from being used by Germany to bomb Britain.

Because during World War II, "the two armies confronted each other, except for the strength factor, the climate often played a decisive role in the victory or defeat of the war. The weather in Britain changes greatly, so does the probability of rainfall. Wet and foggy, it is often impossible to reach out during the day. In this case, Germans will be very tired if they want to enter Britain. Therefore, the "changeable" weather in Britain is an advantage of war. The weather in Britain can be called "top secret" in the war. The "weather forecast" has been blocked since then. It was not until May 9th 1945 that the weather in Britain shed its mysterious cloak for the first time in several years and became public information. The British air force department announced the weather of the day: the whole territory was low in pressure, and the overall temperature felt warmer, sometimes accompanied by thunderstorms! In just a few words, the British and foreigners living in Britain have found a long-lost sense of security.
