During the autumn of 2026, maximum temperatures are expected to be warmer than usual across much of Chile, according to the Seasonal Climate Forecast for the March–April–May (MAM) period prepared by the Chilean Meteorological Directorate (DMC).

According to the report, the prevailing signal will be above-normal maximum temperatures from the northern regions to the southern part of the country, which could translate into warmer afternoons throughout the season.

Regarding precipitation, from the southern part of the Coquimbo region to the O’Higgins region, rainfall is expected to range from Normal to Below Normal, meaning precipitation within the historical range or even below it.

For example, in Valparaíso, rainfall could fall within the lower end of the climatological average, which ranges between 32 and 120 mm for the period.

Further south, from the Biobío region to parts of Aysén, precipitation is projected to be within the Normal to Above Normal range. A similar situation could occur in pre-Andean areas of the Altiplano. Meanwhile, the far north is expected to maintain its typical dry-season conditions.

Minimum temperatures: Colder mornings

Regarding minimum temperatures, between the regions of Valparaíso and Los Lagos, values could range from Normal to Below Normal, which would favor colder mornings and nights.

In the north of the country, minimum temperatures are projected to be Above Normal, while in the southernmost regions temperatures would range between Normal and Above Normal.

Late varieties: Favorable climate scenario

Regarding late blueberry varieties, whose harvest extends between March and April, Patricio González, academic and researcher at the Irrigation and Agroclimatology Research and Transfer Center (CITRA) of the University of Talca, projects an equally favorable scenario.

“We estimate that rainfall would begin from mid-May. Therefore, March and April would present scarce precipitation and moderate temperatures, conditions that will continue to benefit the harvest of late varieties,” he notes.

The specialist explains that although rainfall was recorded in early February, it did not have the intensity or volume necessary to cause damage to the fruit.

According to the expert, the season has shown particularly positive conditions for production. “This 2026 has been very favorable from a production standpoint. Everything indicates that volume expectations will be met, largely thanks to the moderate climate we have experienced, something that had not occurred with this level of stability over the past four years,” he says.

Preventive management in response to greater climate variability

Given this scenario, Consultora Agrícola y Comercial Santa María (CASM Blueberries) recommends that growers continuously monitor weather conditions and work closely with their technical advisors.

Specialists highlight that proactive management, based on up-to-date climate information and timely agronomic decisions, is key to:

  • Protect fruit quality.
  • Safeguard the productive potential of the orchards.
  • Minimize potential economic losses.
