Harvest on a ‘knife edge’ after record breaking spring – analysis
As Government support for farmers hangs in the balance, new analysis suggests farmers could face another poor harvest after UK’s warmest spring ever and driest spring for 50 years.

New analysis [1] suggests that the UK could be headed for another terrible harvest, following the warmest UK spring ever and the driest spring for over 50 years [2] left crops stressed and in poor condition relative to previous years.
The analysis from the Energy and Climate Intelligence Unit (ECIU), estimates that the production of the main arable crops, wheat, barley, oats and oilseed rape could once again be near all-time lows. This would follow the third worst harvest on record last year after the unprecedented extreme rainfall in winter 2023/2024 [3].
The most recent crop development survey [4] published by the Agriculture and Horticulture Development Board (AHDB) identified a major decline in crop condition following months of dry weather this spring. Despite recent rainfall, they concluded that this dry weather has reduced yield potential. By how much depends on what rainfall we see in the coming weeks, leaving prospects for harvest 2025 in the balance.
Tom Lancaster, land, food and farming analyst at the Energy and Climate Intelligence Unit said:
“Climate change is already having a devastating impact on UK farming and our collective food security, pushing up shopping bills and leaving many farmers at the end of their tether. Although it’s too early to tell what the true impact will be of this record-breaking dry spring, we know enough to conclude that it will have had a negative impact. All eyes are on the next few weeks’ weather.
“Scientists are clear that warmer springs are an anticipated feature of climate change, making the impact of a dry spring more severe. Just as the extreme wet weather that we saw last winter was too, and which had such a devastating impact on last year’s harvest. In this volatile context, the outcome of the spending review next week will be a crucial moment for farming in this country, and whether the government realises what’s at stake for UK farming and food security in a rapidly changing climate.”
The ECIU analysis sets out three scenarios. If crop condition is maintained at current levels the analysis assumes yields in line with last year, which would lead to a worst harvest than 2024, making 2025 the second worst harvest on record for the UK.
If crop condition improves in response to rain, and yield recovers to the 10-year average for 2015-2024, the UK harvest would be the seventh worst on record. However, if crop condition continues to decline over the next month and yields were equivalent to 2020 (the worst harvest since detailed records began in 1984), 2025 could be the worst harvest on record.
All scenarios suggest 2025 is likely to be a historically poor harvest, an outcome that would mean three of the worst harvests on record have occurred this decade after a series of extreme weather events.
This comes just as reports [5] suggest the sustainable farming budget could be cut at next week’s comprehensive spending review. This funding is vital to building resilience to climate impacts such as droughts, floods and heatwaves, by improving soil health, planting new hedgerows and trees that can shade livestock and boost pollinators and restoring peatlands to protect communities and infrastructure from flooding.
Commenting on the analysis, Martin Lines, chief executive of the Nature Friendly Farming Network said, “This year’s arable harvest is on a knife edge. Months of dry weather have left my crops stressed, with their yield potential now capped even if we get a good bit of rain. This is what farming in a changing climate looks like. In three years, we’ve had the hottest day ever, the wettest 18 months and now the warmest spring.
“It’s wreaking havoc with my ability to plan and many farmers are now facing yet more financial losses this harvest, just as support for nature-friendly farming is being called into question. Nature-friendly farming is the backbone of rural resilience. Cutting funding now won’t save money; it will cost us all in the long run. This doesn’t just threaten farming in the UK – the consequences will be felt far beyond the farm gate.”
As well as this dry spring, many farmers cropping plans for this year were hit by the extreme rainfall that many in England experienced last September and October, when some English counties experienced their wettest calendar month on record [6] just as winter crops should have been drilled. This delayed a lot of crop establishment to the spring, with spring cropping then more vulnerable to the dry and warm weather that we have seen in recent months.
Dr Clair Barnes, World Weather Attribution Researcher at the Centre for Environmental Policy, Imperial College London, said, "Spring rainfall varies a lot in the UK. It is strongly influenced by the jet stream, a rotating band of air in the upper atmosphere that guides weather systems and can bring either wet or dry conditions depending on its location. That makes it difficult to see long-term trends.
"However, spring temperatures are clearly increasing due to climate change. It is the UK’s fastest warming season and has become about 1.8C hotter compared to 1970. This worsens the very dry conditions when we have a spring with low rainfall, like this year, because higher temperatures evaporate more moisture from the soil and plants.
"Overall, this is bad news for farmers who are expecting smaller harvests of spring crops, like wheat and barley."
