It is said that in Britain it is possible to experience all four seasons within a single day. Although this may be a slight exaggeration,there is no doubt that the weather is so unpredictable that a warm and sunny summer morning can easily turn to a cold,rainy storm within a few short hours. Because of this,there is no custom of designating a certain period of the year when winter clothes are put away and summer clothes extracted. All clothes are kept available at all times of the year in order to be prepared for all eventualities,and shops probably sell nearly as many sweaters and overcoats in summer as they do in winter.
But Britain’s unpredictable climate also gives its citizens a lot of experience in the vagaries of the weather,and this has turned everybody into amateur weather forecasters. People claim to be able to “smell” the rain coming,and predictions of a thunderstorm are rarely wrong. In most cases people use their instincts for these forecasts. If the wind is blowing in the right direction,it is, in fact,possible to smell the approach of rain. A breezeless,humid day with a tang of ozone in the air will also provide accurate predicttions of thunderstorms. And there are other indications,too. A red sunset predicts fine weather the following day,but a red sunrise points to bad weather. Rain can also be predicted by thin clouds that resemble the patterns on a herring’s back,by cows lying down,and by pine cones opening their bristles. In fact,there are many items that can be used to predict rain.
