Colombia’s Coffee Plantations Set To Register Lower Rainfall in May, June’s  Showers Even Lower

Bogota (Coffee Network) – For May, Colombia’s rainfall is expected to fall across much of Colombia’s coffee-growing regions and showers are expected even lower in June. As a result, the coffee research department Cenicafe warns of measures to control of broca, also known as the coffee berry borer.

For May 2026, rainfall conditions are expected to vary by region. Below-normal rainfall is expected to prevail in areas of Bolívar, Cesar, Norte de Santander, Santander, Antioquia, Caldas, Risaralda, Quindío, Valle del Cauca, Tolima, Cundinamarca, Cauca, Huila, and Nariño.

In small- localized areas of La Guajira, Cesar, Norte de Santander, Santander, Tolima, and Cundinamarca, rainfall above normal levels is expected. However, precipitation in the remaining areas is forecast to remain within historical averages.

For June, differentiated weather patterns are also expected across specific sectors of the coffee-growing region.

Below-normal rainfall is expected mainly in Antioquia, Caldas, Tolima, Valle del Cauca, Cauca, Nariño, Cundinamarca, and Santander.

Above-normal rainfall is forecast across broad areas of Nariño, Cauca, Huila, Cundinamarca, Caquetá, Boyacá, Norte de Santander, and Cesar. In the remaining regions, precipitation is expected to remain within historical averages.

But June could be drier than expected. El Niño is likely to emerge soon (82% chance in May-July 2026) and continue through Northern Hemisphere winter 2026-27 (96% chance in December 2026 – February 2027), the National Oceanic and Atmospheric Administration, NOAA said yesterday.

According to latest diagnostics call for a transition to ENSO-neutral conditions continued, as indicated by near-average sea surface temperatures (SSTs) in the east-central equatorial Pacific Ocean. The latest weekly Niño-3.4 index value was +0.4°C, with the westernmost (Niño-4) and easternmost (Niño-1+2) indices at +0.5°C and +1.0°C, respectively.

Coffee borer

Coffee berry borer management remains essential, particularly at the end of the harvest season in the southern departments of Cauca, Narino and Tolima, which are now picking their main harvest. During harvesting and processing, producers should avoid dispersing coffee berry borer adults, Cenicafe added. Once harvesting ends, growers should carry out a “repase” — the collection of ripe, dry, or overripe cherries left behind — and properly dispose of the fruit to prevent the spread of the pest and protect the next harvest.

To ensure high-quality coffee, the following recommendations should be followed:

  • Ensure harvest quality by using tools such as Cromacafé® or Mediverdes® to verify that the share of green cherries in harvested coffee remains below 2.5%.
  • Process coffee by batches.

Additional drying recommendations

  • Improve solar drying efficiency by following the recommendations.
  • When using mechanical or combined drying systems, follow best practices to maximize efficiency while avoiding quality defects.
  • Add value to lower-grade coffee beans (“pasillas”) by processing them separately to create commercial value and increase income. .

Perspective: Morning Commentary for August 11

August 11 – It was generally a quiet night for the markets until early this morning when a headline hit that Iran and Oman were close to reaching a deal. Stock futures rallied, while the dollar index followed Treasury yields lower, along with active selling in the energy- and food-based commodities. The headline had limited impact though in a world that has become skeptical of promises of peace. Stock futures remain steady to firmer at this hour, while the VIX trades near 16 – just above 2026 lows. The dollar index is trading near 99.8 this morning, after recovering from its early morning selloff over the following hour of trade. Yields on 10-year Treasuries are trading near 4.69%, while yields on 2-year Treasuries trade near 4.22%. WTI crude oil is trading near $82 per barrel at this hour, while Brent trades near $88. The grain and oilseed markets are mostly weaker, after failing to recover from this morning’s early selloff that started in the crude oil market.

Perspective: Morning Commentary for August 10

August 10 – The world commodity markets and economy remains at risk amid two wars this morning. Tensions continue to escalate in both the Middle East and the Black Sea – risking pulling other countries into the conflicts. Stocks are down modestly this morning as we start a week of trade in which we’ll see key inflation and retail sales data following a weak jobs report this past Friday. Yet, stocks continue to trade just below record high levels, with the VIX trading near 2026 lows just above 15. The dollar index is trading near 99.7. Yields on 10-year Treasuries are trading near 4.68%, while yields on 2-year Treasuries are trading near 4.23%. The energy and food-based markets are firmer today amid the escalated risks. WTI crude oil is trading near $80, while Brent trades near $85 per barrel. Double-digit gains in the winter wheat markets lead the way for higher grain and oilseed prices.
