London weather seems to be the epitome of the old saying “If you don’t like the weather, just wait five minutes”. Although it enjoys quite a temperate and mild climate and lacks the wild extremes that are found in other areas, London has a reputation for unpredictable and highly changeable weather that is well-deserved.
Myth #1: It’s raining all the time
London has a reputation as an extremely rainy city, which is really not true at all. Overall, London gets less rain than Sydney, Australia or Dallas, Texas, neither of which are considered to be cities that get excessive rain. Perhaps it is London’s propensity for unexpected showers that has earned it the rainy reputation; carrying an umbrella seems almost mandatory amongst residents.
Myth #2: London is very foggy
One atmospheric condition that London has long been linked to is fog, but this has changed in recent years. Long ago, industrial pollution caused a combination of haze, fog, and smog to form into the famed “London Pea Soup” which actually ended up killing thousands in the 1950s. Clean Air Laws have all but eliminated this problem, and London’s fog is now just as ordinary as that of other cities.
London Weather: So when is the best time to visit?
The best time to visit really depends on what you’re looking for. For many people visiting London the warmer months are the ideal time to walk around London enjoying all its attractions from dusk to dawn. Others love the cold and rainy months, whether it’s going Christmas shopping or exploring museums.
There is really no bad time to visit London. The weather has its special charm in each season, and there are good reasons to recommend a visit at any time of year. Here is a little summary if you can’t make up your mind:
- Springtime is magical in London, the city’s numerous gardens and parks come back to life and the weather is cool and mild.
- Summer can be quite warm at times, although the lack of humidity makes it quite tolerable, and there are many outdoor festivals and events to enjoy. And if you’re visiting with kids, make sure to take advantage of London’s many fabulous playgrounds.
- Autumn brings a bit of chill back to the air, wonderful changing foliage, and some terrific activities like Bonfire Night. Enjoy the autumn colours in all its magnificence in Royal Parks like Hyde Park, Richmond Park and Greenwich Park.
- Winter is an enchanting time in London, with wonderful seasonal activities. The weather then is chilly and cold, but not the bitter cold of other northern climates, making outdoor activities still quite pleasant much of the time. Favourite activities during winter include going to markets and enjoying the many museums the city has to offer.
Now let’s dive into some more details about each London weather season:
Winter: Bundle Up and Pack Your Woolies
Winter weather in London: The temperatures in London from December to February are usually above freezing but rarely go higher than about 48F or 9C.
Winter weather in London can be quite changeable, so make sure to pack accordingly and bring accessories such as hats, gloves, and boots to ensure that your visit is a pleasant one. London is at the same latitude as Siberia, which might naturally lead you to think it would be a bitterly cold and inhospitable place, but happily this is not the case.
London is generally quite a nice change for those visitors coming from frigid Northern climates; chilly and damp but not snow-bound or icy. We have the powerful Gulf Stream currents to thank for this meteorological anomaly.
Recent global climate changes point towards shifts in the Gulf Stream that may have an adverse effect on London’s temperatures, but for the time being everything is holding steady.
Rainfall during the winter months can be a factor, London gets an average of 40mm to 50mm of precipitation during the winter months. Bring some rain gear with you or be prepared to purchase some if necessary.
Remember that the same rain you might just shrug off in the summer can be quite unpleasant or even dangerous in the winter; hypothermia may seem unlikely but it can actually happen quite quickly. Travellers who get soaked to the skin in cold London weather and have no way to change into dry things should head for a warm place as soon as possible; a pub with a fireplace would be ideal but even a heated shop would do.
There are sometimes snow or ice storms in London, but these are generally short-lived and the average temperatures are high enough that nothing stays on the ground for very long.
Winter weather in London can be fun; if you are in the city during one of the rare snowstorms, you will likely see the residents playing in the snow and hard at work building snowmen while the temperatures permit.
Spring: Could be a Lion, Could be a Lamb
Spring weather in London: The average temperatures in London during the spring months of March, April, and May are generally between 50F and 60F or 11C to 15C. Mornings may start out a good deal colder and the same goes for the evenings.
Spring climate in London can be some of the best and worst sorts of weather. There is nothing as nice as the warmth of a spring day, reminding us that the cold and dreary winter will soon give way to sunny days and flower-scented evenings.
There is nothing so cruel as when that warm spring day is then drenched with a sudden downpour of icy rain and buffeting winds that seems intent on reminding us rather unpleasantly that winter does not give up its grip so easily.
Spring visits to London require flexibility and preparation; pack accordingly and consider alternatives for outdoor activities or else you risk having the vagaries of Mother Nature derail your best laid plans. Despite the uncertainties, springtime is a lovely time of year to visit London; people are getting out and enjoying the weather when it is fine and everything seems to be green and growing and full of promise.
Packing a little bit of everything is probably the best course, as you may find you need both cold weather and warm weather clothing and outerwear during your stay in the city.
There is a good deal of rain in London during the spring months, expect anywhere from 37mm to 46mm per month. Umbrellas and waterproof jackets are good things to bring with you, or they can be purchased during your visit if you would prefer.
Londoners are used to dealing with the peculiarities of the weather here, and stores carry a dizzying variety of rain gear.
Spring climate in London can put a damper in outdoor plans, but the delightful days more than outweigh the risk of spring showers.
Summer: Warm and Getting Warmer?
Summer weather in London: Temperatures in the summer months of June, July, and August usually hover around 70F or 20C, although there are times when the mercury has climbed as high as 100F or 37.9C.

The London weather forecast for summer is usually quite good. The city has a temperate and mild climate, which means temperature extremes are rare.
Summer is usually warm and sunny with occasional rainstorms, but being London, you can expect a certain changeability in the forecast as well. A day might start out dreary and wet only to turn into a glorious warm day, or vice versa.
London lacks the oppressive humidity that is commonly found in many locations during the summer months, and this in itself makes it a delightful place to be in the warm season.
The Gulf Stream currents are largely responsible for London’s mild climate, and global changes in these currents may eventually lead to more extreme temperature changes. For now, however, the weather is fairly stable and temperatures rarely get really hot even at the height of the summer.
London has a great deal of green space, parks, and grassy areas that are especially appealing during the summer months, and there are many outdoor activities such as open-air concerts, and festivals.
Rainfall during the summer months usually ranges from about 45 mm to 55mm.
Be ready for anything when it comes to packing for a summer visit to London. Warm weather clothing is a must, but make sure to bring a lightweight waterproof jacket, and a jumper might also be useful for the occasional chilly evening.

The autumn weather forecast for London is not all that different from the London weather forecast for spring. During these transitional seasons, the weather is usually mild and pleasant with a fair amount of rainfall and changing skies.
Some years, the weather can stay quite summer-like well into October, while other years it would seem like winter by the time November rolls around.

To celebrate Guy Fawkes Day, there are many fireworks displays and bonfires that take place all across the city, and the cool autumn London weather is the perfect time to enjoy these festive outdoor events.
The vibrant autumn foliage of September begins to fall in October, and by November it is easy to imagine wintertime is just around the corner. Happily, London’s climate is quite temperate so autumn weather is not the bitter introduction to winter that you might find in destinations with a more extreme climate.
Packing a warm coat and accessories like gloves and a hat are advisable, because a warm and pleasant autumn day in London can easily be followed by days of cold and damp.
Ever unpredictable, London weather requires some patience and flexibility from visitors.
To its credit, London weather is quite changeable so a dreary morning could well give way to a beautiful afternoon. Londoners are accustomed to the capricious nature of the elements and are generally prepared for anything when it comes to weather, and it is advisable for you to follow their lead.
The autumn weather forecast for London is a bit unpredictable, but this time of year is a very nice time to visit the city.
The most reliable UK weather forecast app
The weather forecast is known for being painstakingly inaccurate in the UK. Not so much because the weathermen and weatherwomen are doing a bad job, but because Britain is a small island in the middle of the ocean surrounded by winds from all directions making the weather highly variable.
Who predicts the weather in the UK? It’s the Met Office, United Kingdom’s national weather service which is streaming the weather data to all the other weather apps and websites like BBC weather, Google weather and The Weather channel.
So does it matter which weather app you’re using?
Since all the apps are using the same data coming from the Met Office, it’s more down to personal preference which one you should use. If you prefer asking Google Assistance for the weather in the morning or rather watch the BBC weather forecast on TV it all comes down to the reliance on the same data source.
The forecast will often be displayed in different ways though, so even if the underlying data is the same you might perceive the prediction differently. The Met Office also has its own website and app where you’ll also be given warnings and very detailed technical weather forecasts.
