"From Yellow Fields to Golden Wheat - The Cycle of the Circles"
What Time of Year Heralds the Start of Crop Circle Season?
In the UK, the crop circle season follows the natural growing cycle of the crops themselves. The first possible formations can appear in oilseed rape, also known as canola, which produces the striking bright yellow fields seen across the countryside in spring. This crop can be mature enough to hold a formation from around the beginning of April, although not every year produces circles in oilseed rape.
Some years, the season begins later, once barley has grown tall and strong enough to hold a visible formation. This usually means the first circles may not appear until late May or June.
When Do Crop Circles Usually Appear?
In the UK, the first formations can appear from April or May, with activity gradually increasing as spring turns into summer. The season often reaches its peak in late July and August, when the fields are full, golden, and close to harvest. At the height of the season, several formations have sometimes been reported within the same short period, occasionally even overnight.
Although the UK is the most famous location for crop circles, they are not exclusive to Britain. They have been reported in many countries around the world and generally follow the local growing seasons. In the United States, for example, formations are more commonly found in crops such as corn/maize or soya.
Where Do Crop Circles Usually Appear in the UK?
The traditional heartland of the UK crop circle season is the ancient landscape of Wiltshire, especially around areas such as Avebury, Devizes, Marlborough, Alton Barnes, and the wider Vale of Pewsey. Hampshire has also been a regular location over the years.
In more recent seasons, Somerset and Dorset have also produced notable formations, and circles can occasionally appear elsewhere across the country. Early in the season, reports are usually few and scattered. As the summer develops, the number of formations tends to increase.
The Crop Cycle: From Yellow Fields to Golden Wheat
The UK crop circle season often appears to follow the natural order in which crops mature:
Oilseed rape / canola usually comes first, bringing the possibility of early spring circles in bright yellow fields.
Barley follows, often becoming suitable from late spring into early summer.
Wheat usually dominates the later season, producing many of the classic golden formations associated with July and August.
From time to time, crop circles have also appeared in less common crops, including linseed, borage, oats, poppies, beans, and mixed fields.
When Does the Season End?
The season ends when the crops are harvested. In the UK, this usually means mid to late August, although timing depends on weather, crop condition, and the decisions of individual farmers.
Once the fields are cut, the landscape is effectively reset. The formations disappear, the season closes, and the cycle begins again the following spring.
A Note for Visitors to the Circles
Anyone visiting a crop circle should always remember that these formations appear on private farmland. Public access is not automatic. Always check whether permission has been granted before entering a field, follow any posted guidance, avoid damaging crops, park responsibly, and respect the farmer’s wishes.
For every farmer, the field in which a crop circle is discovered is also their livelihood. Respect for the land should always come first.
