El Niño threatens South Africa's crops, but a record maize harvest cushions the blow

What the record 17.7-million-tonne count actually tells us

South Africa's best-known agricultural economist, Wandile Sihlobo, also the country's Agriculture and Land Envoy, opened November with reassurance for a nervous summer. In a Daily Maverick analysis on 2 November, he argued that farmers are planting the 2026–27 summer grain and oilseed crop from unusual strength: the Crop Estimates Committee's ninth and final estimate, released on 27 October, puts the 2025–26 maize harvest at 17.69 million tonnes, the largest ever recorded.

The timing is what makes the number matter. The Pacific has swung into what the Weather Service says could become one of the strongest El Niño events in living memory, promising a hotter, drier summer through the first quarter of 2027. Farmers are planting early into soil moisture banked by September rains and a long 2025–26 wet season. The question is whether a record harvest can buy the country enough time to ride out the dry spell.

What the harvest ledger shows; down to the tonne

The ninth estimate, carried by the Reuters wire and South African outlets, revises the crop up by nearly 169,000 tonnes from the September figure of 17.52 million, and about 6% above the 16.65 million tonnes of the previous season. White maize accounts for 9.78 million tonnes, yellow maize for 7.91 million; the average yield of 6.49 tonnes a hectare is exceptional, and the Free State, Mpumalanga and North West together produced 82% of the crop.

The forward look is more cautious. The same committee release carried the intentions survey: farmers intend to sow 4.5 million hectares of summer grain and oilseed, 2% less than last season and roughly the five-year average. Maize alone accounts for 2.39 million intended hectares; down 12.4%, or 337,000 hectares, the smallest maize area since 2018–19, according to Standard Bank's agribusiness desk. These are intentions, not plantings; the final area will only be known with the committee's preliminary planting data on 27 January 2027.

The buffer is real: roughly 2.4 million tonnes of opening stocks against annual consumption of about 12 million tonnes. Late-October prices reflected the surplus, white maize around R3,700 a tonne and yellow around R3,800, down from above R4,000 a month earlier. December 2026 SAFEX futures closed on 29 October near R3,837 for white and R3,822 for yellow, with spot prices at R3,787 and R3,800, the market trading close to export parity, a sign of comfortable domestic supply. In grain terms, South Africa is a net exporter this year.

Why the next four months decide everything

What nobody can yet say is whether farmers will hold to their stated intentions as El Niño deepens and input costs bite. The decisive variable is the January–February rainfall over the maize belt; the period that makes or breaks yields. A second unknown is the price path: as regional demand gathers pace in 2027, maize prices will probably climb from late-October levels, but how far depends on the weather and on how aggressively neighbouring buyers turn to South African grain. The size of the 2026–27 crop, and with it the supply picture for the second half of 2027, is entirely unwritten.

How food prices, not harvests, will touch households

For consumers, the crop is measured in rand, not tonnes. Full silos have kept SAFEX prices soft, cushioning the animal-feed chain and the price of staple foods; a buffer that matters in an economy where Finance Minister Enoch Godongwana has already flagged El Niño as a risk to output and production costs in his 2026 budget statement. The same low prices, however, squeeze farmers facing rising fertiliser and fuel costs. Regionally, with South Africa a net exporter and food prices under pressure elsewhere, the record harvest is already weighing on maize prices across southern Africa. A drought in one season can become a price shock in the next; which is why this record crop is being read as insurance, not victory.

What the 2015–16 playbook suggests about 2026–27

The last comparable episode is instructive. The 2015–16 El Niño brought southern Africa its worst drought on record, with five South African provinces declared disaster areas. This time the country enters the dry season with the opposite of a deficit: a record crop, 2.4 million tonnes of opening stocks, and prices with room to absorb shocks. That cushion is a one-season instrument; it protects the 2026–27 marketing year, while the risk migrates to 2027–28 if the new planting fails.

There is also a global divergence worth watching. While India braces for a 28–32% drop in maize output and Southeast Asian rice markets tighten, South Africa's surplus is pressing regional prices down; a reminder that climate risk is rarely synchronised, and that one region's harvest can steady another's shortfall. The constraint is at the farm gate: with fertiliser and diesel costs elevated, the farmers being asked to plant through a drought warning are doing so on thinning margins. The policy question is whether the state treats the grain buffer as a strategic asset to be husbanded, or lets the market run it down before the weather verdict arrives.

Where the pressure moves once the silos are full

A record crop does not distribute itself. The surplus is already reshaping trade: South African maize is flowing out while imports sit at negligible levels, and analysts expect sustained downward pressure on regional prices through the marketing year. That is good news for import-dependent neighbours and for the domestic feed, poultry and dairy chains. It is less comfortable for grain farmers, whose margins are compressed from both sides; soft output prices and firm input costs.

The second pressure point is water. El Niño is arriving on top of a municipal water crisis, and demand for boreholes, storage and emergency supply typically surges when the rains underperform; the pattern the 2015–16 drought established. The third is political: a season that begins with full silos and ends with failed plantings would flip the public conversation from food security to blame, which is why the agriculture minister and the Weather Service have been sounding public warnings since mid-October. Standard Bank's agribusiness desk is watching actual planting decisions in the coming weeks as the true signal of how the season lands.

When we will know whether the early planting survives

The calendar of the next season is already set. The Crop Estimates Committee's preliminary planting data, due on 27 January 2027, will give the first hard reading on whether farmers held their intended area; Sihlobo calls it the number to watch. Before that, the Weather Service's rolling seasonal outlooks and the December peak of the El Niño itself will shape expectations; NOAA gives a greater than 83% chance the event stays strong to very strong through January–March 2027. Through the first half of 2027, supplies are largely spoken for. What happens after mid-year depends entirely on the crop now going into the ground; and the traders' tell will be SAFEX futures and the pace of exports.
