Signs of Spring: What to Look Out For
Spring is a glorious time in nature. After the cold and dark of winter, signs of new life begin to emerge. The sights, sounds, and smells bring hope and cheer as more light and warmth encourage unfurling leaves, colourful blooms, and thriving wildlife. But when does spring really start, and what are the key signs to look for?
When Does Spring Start?
Technically, spring has two start dates. The astronomical start of spring is marked by the equinox. This usually falls on the 20th of March or a day either side. This is the point when daylight and dark hours become equal, signaling the official transition from winter to spring.
Meanwhile, the meteorological definition of spring is based on temperature patterns and divides the year into four equal seasons. Under this system, spring begins on the 1st of March and lasts until the 31st of May.
Of course, nature doesn’t always follow a set timetable. So, it’s best to observe the arrival of spring through the changes happening all around us.
Tree leaves and blossom
One of the most noticeable signs that the seasons are shifting are the fresh new leaves. Throughout March, the bare branches of ash, beech, oak, and rowan begin to burst into bud, while alder, field maple, and silver birch reveal their first delicate leaves. Meanwhile, blackthorn and crab apple trees begin to blossom, covering their branches in frothy white flowers.
These early signs of growth not only transform the landscape but also provide an essential food source for insects. Blossom on hedgerows is often one of the first significant sources of pollen for bees and butterflies.
First Flowers Blooming
As the days grow longer and the sun begins to warm the earth, early spring flowers bring a welcome splash of colour to gardens, parks, and woodlands. Snowdrops and crocuses often appear first, sometimes as early as mid-February. They’re soon followed by the bright yellow blooms of colt’s foot and the delicate white petals of wood anemones in early March.
Later in the month, cuckoo flowers and bluebells begin to emerge, adding a riot of pinks, purples, and blues to the seasonal palette. These flowers not only signal the arrival of spring but also play a vital role in supporting pollinators such as bees and butterflies.
Insects and Amphibians Awakening
The first bumblebees emerge from hibernation in March, while butterflies such as peacock and small tortoiseshells can often be spotted as early as late February. Alongside these winged wonders, beetles, spiders, and ladybirds start to appear, taking advantage of the warming temperatures.
Amphibians are also on the move at this time of year. Frogs emerge from their winter hiding places in ponds, log piles, and stone crevices, with one thing on their mind- spawning. From February through to April clusters of frog spawn appear in shallow, still waters. This is a great time to spot frogs and other amphibians as they become more active in search of mates.
Birds Arriving and Nesting
The sound of birdsong filling the air is one of the most iconic signs of spring. Blackbirds, in particular, become more vocal at this time of year as they search for a mate. Their rich, melodic calls are most commonly heard at dusk, making it the perfect time to pause, take in the sunset, and listen to nature’s evening chorus.
Migratory birds also begin to return to the UK after spending the winter in warmer climates. Blackcaps, chiffchaffs, and sand martins are among the earliest arrivals, with sightings becoming more frequent in March. Meanwhile, resident species such as blackbirds, blue tits, and great tits start their nesting preparations. Blackbirds and blue tits typically begin to build their nests from late February, while great tits follow in early March.
Where to See the First Signs of Spring
The beauty of spring is that its arrival can be observed almost anywhere. Whether you have a garden, a balcony, or even a window box, keeping an eye on nearby plants and trees will reveal subtle changes as the season unfolds. Street trees, parks, and local green spaces also offer fantastic opportunities to witness nature’s seasonal transition. And, of course, rivers and wetlands are teeming with life at this time of year, making them ideal spots to look for birds, insects, and amphibians.
If you’d like to encourage more wildlife into your garden, there are plenty of simple steps you can take to make it a haven for nature. From planting native flowers to providing shelter for birds and pollinators, small changes can make a big difference.
Rivers are at the heart of our local landscapes. Whether you’re casting a line, exploring a riverside trail, or simply basking in the beauty of nature, you can help protect these special places now, and for generations to come.
