Preparing for El Niño 2026-27
THE WINDY EL NINO - a strategic outlook report for New Zealand farmers, growers, and rural business
The August model runs have escalated the picture. This El Niño is now tracking to be the strongest Pacific Ocean event in at least 150 years — into the territory of the extreme 1877-78 event. But New Zealand's version of it is not the hot, blocked summer most people expect: it is a windy one, and that changes what preparation actually looks like. The fully revised August edition of Blue Skies' El Niño report is available now.
The world's leading forecast systems, run independently, now agree the Pacific event will peak above every El Niño in the instrumental record. Yet the New Zealand outlook has not escalated by the same amount — and understanding why is worth more to your planning than the headline number. The season the models show is a windy, changeable westerly summer: dry in the east and north, wet on the alps and the West Coast, temperatures near normal. Drought delivered by wind and evaporation, not heat — the 1982/83 template, not a heatwave. The report explains the mechanism, what it changes on your farm, and the month-by-month decisions it forces from September through March.
This is the third edition of a report that revises openly as the evidence moves — the August edition supersedes the July update and the original May outlook, and shows you exactly what changed and why. Subscribers to the Outlooks will also receive the September revision at the point where the season commits.

What has changed and what hasn't — the record-strength reassessment, and why a record ocean event does not mean a record New Zealand drought
The One Page — the whole season and the do-by-when list, on a single page
What history says — 1877/78 (first-hand stock inspectors' records), 1982/83 and 1997/98, and the practical lessons each carries for this season
Three scenarios, reweighted — the central case, the record-strength upside, and the moderated case, with what each looks like by February
