Latest updates and advice

  • Crops have established over much of the southern agricultural areas that experienced an earlier break of season. In northern areas, crops have been sown dry with growers adjusting their seeding programs as appropriate in preparation for the predicted end of break of season at the end of May.
  • The Bureau of Meteorology’s rainfall outlook for June to August 2025 indicates near normal rainfall for the lower west of WA. The pattern of above normal temperatures is expected to continue through winter with forecasts of unusually high daytime temperatures over most of Australia. See the Bureau’s seasonal outlook video for details and check monthly updates to the Seasonal Climate Outlook.
  • While some areas have received some dam-filling rainfall, other areas remain drier. Plan ahead to ensure there is enough quality water available for livestock until break of season and formulate or enact contingency plans. See Livestock management and Water sections for information to assist decision-making, particularly for dry seasonal conditions.
  • Consider the timing of soil mixing and soil inversion; these operations should be carried out when the soil is moist to reduce the risk of soil erosion and ensure the best amelioration outcome. See Soils section for further information.

Livestock

  • Consider stock water requirements. Plan to ensure there is enough quality water available into early winter and formulate or enact contingency plans. Visit the Water for livestock page to learn more. 
  • Pastures have germinated but Pastures from Space™ shows growth rates have slowed. Review feed budgets and use supplementary feeding until sufficient pasture is available to support stock. Factor in multiple plans, including worst-case scenarios such as supplementary feeding for longer if conditions remain dry and pasture Feed on Offer (FOO) is low or there has been a false break. 
  • Dry sowing of forage cereal crops can provide early grazing and allow deferment of regenerating annual pastures. Sow crops at 80-100 kg/ha, followed by a nitrogen application of 5-10 kg/ha for low soil nitrogen paddocks. Ensure crops are protected from pests and wait until plants are well anchored before grazing.
  • Keep an eye out for insect pests of regenerating and newly sown legume pastures such as red-legged earth mite and lucerne flea. Severe infestations can reduce feed availability and applications of insecticide may be required. Chemical control options can be found in the Autumn/Winter Insecticide Guide 2025, being mindful of any withholding periods for grazing. See pasture and grazing management for further information.
  • Confinement feeding is an option to reduce overall energy demand and allow pastures to establish at the break of season. Pregnant ewes should be released from confinement at least 2-3 weeks prior to the start of lambing. Read our factsheet to find out more about considerations when setting up confinement feeding areas.  
  • Be vigilant for signs of kikuyu poisoning in sheep and cattle. Toxicity is more common in stock grazing lush kikuyu dominant pastures and is most likely 2 to 3 weeks after a rainfall event.  See StockedUp (May 2025 edition) for management tips and signs of kikuyu poisoning.
  • Be aware of the symptoms of Annual Ryegrass Toxicity (ARGT). It’s important that purchased feed is tested for ARGT.
  • Contact your local DPIRD field vet to report unusual disease signs, abnormal behaviour or unexpected deaths in your livestock.
  • See the latest StockedUp newsletter for a range of seasonal production advice and management tips.

Crops

  • Refer to the 2025 WA Crop Sowing Guide for some management tips on major crops.
  • Refer to the Rainfall to date tool to assist with seasonal decision-making. The tool produces graphs using daily rainfall data from weather stations across the state and displays how the season is tracking compared to historical date displayed in deciles. Growers should also consider additional factors such as stored soil moisture, soil water-holding capacity, stored nitrogen, rainfall timing and intensity for in-season decisions.
  • For information to identify and manage your crop pests and diseases throughout the season refer to PestFacts WA.

Soils

Consider the timing of soil mixing and soil inversion; these operations should be carried out when the soil is moist to reduce the risk of soil erosion and ensure the best amelioration outcome. For deep ripping, timing involves finding the appropriate window when the soil is moist, whilst not conflicting with seeding. The options include:

  • deep rip after seeding but early enough not to disturb establishing plants too much (generally within 3 days of seeding) although this can also reduce crop establishment
  • deep rip in the inter-row of crops sown on wide rows during the growing season, which requires precision and patience
  • deep rip opportunistically after significant out-of-season rains, which may require waiting until spring then ripping fallowed paddocks.

For soil inversion or mixing, it is imperative to plan management of wind erosion risk after the operation.

  • Rolling susceptible sands with a ridged or 'sheeps foot' roller that leaves a compressed, ridged or pitted surface may slightly reduce wind erosion risk, but will not remove it.
  • Amelioration techniques that leave a cloddy surface can reduce erosion levels and should not be rolled until immediately prior to sowing. 
  • Sowing cereal crops into the wet soil as soon as possible after inversion will also minimise risk by achieving an emergence at the earliest possibility. Damage to the establishing crop through sand blasting remains a risk.
  • Late amelioration, generally that completed during June, is more profitable than late crop sown into non-ameliorated soil.

Landholders are encouraged to assess and manage wind erosion risk at each stage of the cropping year:

Climate outlook

Rainfall outlook for June 2025 from the Bureau of Meteorology, updated 19 May, shows normal rain is highly likely for most of the state, including parts of the agricultural area. The seasonal rainfall outlook for June to August 2025 indicates near normal rainfall is likely for the lower west of WA. See the Bureau’s seasonal outlook video for more details.

Many international climate models have a neutral to above normal rainfall outlook for the South West Land Division for this period, from their May runs. A neutral outlook means extreme wet or dry events are less likely, and a wide range of rainfall amounts remains possible.

The pattern of above normal temperatures continues through winter, with chances of unusually high daytime temperatures being elevated over most of Australia.
