The Haymaking Weather Window: Reading Forecasts for Quality<\/h2>\n

Every experienced hay producer knows the saying: “Hay is a weather crop.” More than any other field crop, the quality of hay is determined by the 36\u201372 hour window between cutting and baling \u2014 a window entirely controlled by weather. Reading forecasts accurately and translating them into cutting decisions is one of the most valuable skills in haymaking. Understanding the haymaking weather window<\/strong> is what separates operators who consistently produce top-grade hay from those who accept whatever nature delivers. This guide lays out how to interpret weather forecasts specifically for haymaking, what variables matter most, and how to decide when to cut.<\/p>\n<\/div>\n

The Curing Cycle and Weather Requirements<\/h2>\n

Freshly-cut hay drops from 70\u201380% moisture to baling-ready 16\u201318% moisture through evaporation driven by ambient air conditions. The required time depends on weather:<\/p>\n

\u2600\ufe0f Ideal Conditions<\/p>\n

Temperature 26\u201332\u00b0C, humidity <50%, wind 10\u201320 km\/h, full sun. Curing time: 24\u201336 hours.<\/strong> The three-day window can easily handle first-cut alfalfa with conditioner.<\/p>\n<\/div>\n

\ud83c\udf24\ufe0f Good Conditions<\/p>\n

Temperature 22\u201326\u00b0C, humidity 50\u201365%, light wind, mostly sunny. Curing time: 36\u201348 hours.<\/strong> Need to start early and use tedder to stay ahead of schedule.<\/p>\n<\/div>\n

\n

\u26c5 Marginal Conditions<\/p>\n

Temperature 18\u201322\u00b0C, humidity 65\u201375%, variable wind. Curing time: 48\u201372 hours.<\/strong> Tedding mandatory; watch for overnight dew delays. Small baled formats preferred.<\/p>\n<\/div>\n

\n

\ud83c\udf27\ufe0f Poor Conditions<\/p>\n

Temperature <18\u00b0C, humidity >75%, rain probability >30%. Don’t cut.<\/strong> Either wait for better weather or plan for silage\/haylage instead of dry hay.<\/p>\n<\/div>\n

The Three Variables That Matter Most<\/h2>\n

Of all the weather variables in a typical forecast, three are most relevant for haymaking decisions:<\/p>\n
