The British weather can be described as being somewhat changeable, unsettled, unpredictable and mostly damp. It does rain a lot, but it can also be extremely pleasant. Britain enjoys a temperate climate brought across the Atlantic by the warm waters of the Gulf Stream, a constant flow of warm water that starts in the Caribbean. This means that Britain enjoys a warmer climate than it ought to, according to its northerly latitude. Unfortunately, these warm waters also bring with them a great deal of moisture, meaning that rain is a common occurrence, sometimes accompanied by wind, especially in March, or fog in November.
Expect it to be cold, foggy and damp, with somewhat subdued sunlight and occasional gales. Due to Britain’s northerly latitude, 51 degrees in the south of England, to be exact, you can only expect to get between seven and eight hours of daylight in the winter, mainly between 8:00AM and 4:00PM. Sometimes it can remain overcast all day, with low, grey cloud cover. This can make things a little dark and depressing at this time of year, especially when it stays so dark all day that the street lights remain on! You can expect temperatures between 28 degrees and 50 degrees Fahrenheit, but it may feel colder due to the damp. You can also expect frost and ice, and of course, rain, but little in the way of snow. Do not, however, discount the sun, it does, in fact, shine quite often, no matter what anyone says to the contrary. Also expect and be careful of patches of fog and ice, especially when driving at night or early in the morning.
The wettest time of the year, without doubt. During the months of March and April, although the plants are budding, the temperatures are rising, generally in the 40s and 50s, and the days are getting longer, it can be very stormy, especially during March, when one gale after another seems to batter Britain from the Atlantic. The good news about March is that, on or about the 21st of the month, the clocks are moved forward one hour into British Summer Time. You have heard the term April showers, well, that describes the month of April here. During this month, spring is firmly underway, and the countryside really greens up. Expect the occasional early morning frost, with misty patches, plenty of showers, and sunny intervals.
By far the best season for weather, although it can still be highly changeable. May through to September should be warm, and more or less sunny, with temperatures in the 60s and 70s, dropping down to the high 40s and low 50s at night. If you are visiting for the purpose of seeing the crop circles, then June, July, and the first half of August, are the best times to come. However, be prepared for rain, and bring with you some light weight waterproof clothing and some waterproof footwear. It can be muddy underfoot if you intend to venture into the crop circles. As I am writing this guide, it is a beautiful June morning in Salisbury, England. Although there are some clouds in the sky and it is a little hazy, the sun is shining and the temperature must be in the 70s, with a light breeze. This is a typical summer’s day in the south of England. Apart from this, another great feature about summer in Britain is the amount of daylight available. At mid summer, it is light from before 5:00AM to about 10:00PM, and the further north you go, the better it gets!
Again, a very nice season, mostly because of the colors of the trees and the falling leaves. Autumn is known as autumn in Britain, and not as fall. As this season progresses from the month of September, the daylight hours decrease and the temperatures start to fall. On or about October 21st, the clocks are moved back one hour to Greenwich Mean Time (GMT), bringing dusk to about 6:00PM at this time. Expect temperatures to be anywhere from the 40s to the 50s, with increasing frosts, fog, and gales as winter approaches.
