The days are still pleasant, the course looks good and it is easy to leave the controllers as they were in August. Yet turf water demand drops quickly, and an <strong>autumn irrigation schedule<\/strong> that is not adjusted in time causes waterlogging, disease, nutrient leaching and water consumption that nobody needs.<\/p><p>Below we go through five adjustments worth making at this time of year: calibrating to evapotranspiration, redistributing run times and start times, using rainfall sensibly, watching problem areas and taking the opportunity to check the system.<\/p><svg class=\"info\" viewBox=\"0 0 720 410\" role=\"img\" aria-label=\"In this article\"><rect width=\"720\" height=\"410\" rx=\"6\" class=\"svg-bg\"\/><text x=\"28\" y=\"42\" class=\"svg-t\">In this article<\/text><line x1=\"28\" y1=\"54\" x2=\"120\" y2=\"54\" class=\"svg-line\"\/><path d=\"M73.1,89.0 L73.1,111.0 L54.0,122.0 L34.9,111.0 L34.9,89.0 L54.0,78.0Z\" class=\"svg-hex\"\/><text x=\"54\" y=\"106\" text-anchor=\"middle\" class=\"svg-n\">1<\/text><text x=\"94\" y=\"97\" class=\"svg-i\">Adjust autumn irrigation scheduling to the pace of<\/text><text x=\"94\" y=\"117\" class=\"svg-i\">evapotranspiration<\/text><path d=\"M73.1,153.0 L73.1,175.0 L54.0,186.0 L34.9,175.0 L34.9,153.0 L54.0,142.0Z\" class=\"svg-hex\"\/><text x=\"54\" y=\"170\" text-anchor=\"middle\" class=\"svg-n\">2<\/text><text x=\"94\" y=\"161\" class=\"svg-i\">Redistribute run times and start times in autumn irrigation<\/text><text x=\"94\" y=\"181\" class=\"svg-i\">scheduling<\/text><path d=\"M73.1,217.0 L73.1,239.0 L54.0,250.0 L34.9,239.0 L34.9,217.0 L54.0,206.0Z\" class=\"svg-hex\"\/><text x=\"54\" y=\"234\" text-anchor=\"middle\" class=\"svg-n\">3<\/text><text x=\"94\" y=\"225\" class=\"svg-i\">Make use of rainfall without being fooled by it<\/text><path d=\"M73.1,281.0 L73.1,303.0 L54.0,314.0 L34.9,303.0 L34.9,281.0 L54.0,270.0Z\" class=\"svg-hex\"\/><text x=\"54\" y=\"298\" text-anchor=\"middle\" class=\"svg-n\">4<\/text><text x=\"94\" y=\"289\" class=\"svg-i\">Watch problem areas and dry spots<\/text><path d=\"M73.1,345.0 L73.1,367.0 L54.0,378.0 L34.9,367.0 L34.9,345.0 L54.0,334.0Z\" class=\"svg-hex\"\/><text x=\"54\" y=\"362\" text-anchor=\"middle\" class=\"svg-n\">5<\/text><text x=\"94\" y=\"353\" class=\"svg-i\">Use the moment to check the system before winter<\/text><\/svg><h2>Adjust autumn irrigation scheduling to the pace of evapotranspiration<\/h2><p>The basis of any autumn irrigation scheduling is understanding how much water the soil-plant system actually loses. Evapotranspiration drops markedly as days shorten and nights cool, and irrigation should follow it closely, not wait for the turf to show signs.<\/p><p>If you have a weather station or nearby reference data, use it to recalculate run times weekly. If not, a practical approach is to reduce inputs in steps, checking with the probe and by visual inspection that the soil profile keeps enough moisture. Avoid abrupt jumps: it is better to lower a little each week than to cut all at once and find dry areas.<\/p><ul><li>Review the controller&#8217;s percentage adjustment, instead of reprogramming station by station.<\/li><li>Note each change and its date, so you can compare afterwards.<\/li><li>Distinguish between greens, tee boxes, fairways and rough: they do not all drop at the same rate.<\/li><\/ul><h2>Redistribute run times and start times in autumn irrigation scheduling<\/h2><p>In summer you irrigate at night to minimise losses and respect play. In autumn the nights are colder and longer, and the turf takes longer to dry. If irrigation finishes very late, the leaf stays wet for hours at dawn, just when pathogens thrive best.<\/p><p>A good practice is to bring forward the start of the cycles, so they finish earlier and leave room for the dew to dry in the sun. In addition, autumn irrigation scheduling allows lower frequency and greater depth in areas where the soil permits, which encourages rooting. On sand greens it may be necessary to keep lighter, more regular inputs, because they store little. Adjust this with the help of the team that knows each sector.<\/p><p>A detail that gets forgotten: changes of schedule also affect staff. If there is mowing or treatment first thing, coordinate with the team so irrigation does not coincide with it and nobody has to work on waterlogged leaf or walk over freshly watered areas.<\/p><figure class=\"ph\"><img loading=\"lazy\" src=\"https:\/\/totalgreenkeeper.com\/wp-content\/uploads\/2026\/10\/ph-159-1.jpg\" alt=\"Greenkeeper checking a controller during autumn irrigation scheduling\" width=\"1200\" height=\"675\" loading=\"lazy\" decoding=\"async\"><figcaption>Greenkeeper checking a controller during autumn irrigation scheduling<\/figcaption><\/figure><h2>Make use of rainfall without being fooled by it<\/h2><p>Any autumn irrigation scheduling plan must account for rain. Autumn rain episodes in the Mediterranean can be intense and infrequent. A heavy shower is not the same as a useful input if the water runs off or ponds instead of infiltrating. So, before suspending irrigation after a storm, check how much water has really entered the profile.<\/p><p>If the course has a rain gauge, record rainfall by event. Without one, the moisture probe or simply a soil core gives you reliable information. A good protocol for autumn irrigation scheduling includes:<\/p><ol><li>Pausing automatic irrigation when the forecast is reliable and the soil is well supplied.<\/li><li>Resuming with reduced run times after a few days, not with the old ones.<\/li><li>Checking the low areas, where water takes longer to drain.<\/li><\/ol><p>That way you avoid wasting water and also avoid the course going into winter saturated.<\/p><h2>Watch problem areas and dry spots<\/h2><p>Reviewing autumn irrigation scheduling is also a good moment to detect anomalies that summer masked. With less general water stress, localised dry spots, faulty overlaps and waterlogged areas become more obvious. Walk the course first thing and note which sectors do not respond to the adjustment made to the rest.<\/p><p>Three situations tend to appear: areas that keep drying out because of poor sprinkler coverage, areas that waterlog because of excess input or poor drainage, and areas where shaded turf never dries. Each requires a different response and, often, specific scheduling by sector. A simple inspection report, with a photo or sketch, helps the team avoid relying on memory to return to them.<\/p><p>This review of autumn irrigation scheduling is not just about touching the controller: it is about looking at the course with fresh eyes and correcting what summer hid.<\/p><figure class=\"ph\"><img loading=\"lazy\" src=\"https:\/\/totalgreenkeeper.com\/wp-content\/uploads\/2026\/10\/ph-159-2.jpg\" alt=\"Green with uniform moisture after adjusting autumn irrigation scheduling\" width=\"1200\" height=\"675\" loading=\"lazy\" decoding=\"async\"><figcaption>Green with uniform moisture after adjusting autumn irrigation scheduling<\/figcaption><\/figure><h2>Use the moment to check the system before winter<\/h2><p>The lower pressure of play and water demand opens an ideal window for system maintenance. A well-thought-out autumn irrigation schedule includes inspection tasks that avoid breakdowns the following spring:<\/p><ul><li><strong>Sprinklers<\/strong>: check rotation, nozzles, throw distance and arcs; clean filters.<\/li><li><strong>Valves and solenoids<\/strong>: verify opening, closing and watertightness.<\/li><li><strong>Pumping and pressures<\/strong>: compare flows and pressures with the usual values.<\/li><li><strong>Pipes and valve boxes<\/strong>: locate leaks and repair what is outstanding.<\/li><li><strong>Controllers<\/strong>: check sensors, wiring and backups of the programming.<\/li><\/ul><p>If winter brings frost in your area, also plan the protection of exposed elements and the draining of vulnerable sections. Leaving it to the last moment usually proves expensive.<\/p><p>Keep a record of what was checked and what is outstanding. A short list, with an owner and date, prevents minor repairs from piling up until they become irrigation shutdowns in the middle of the season.<\/p><svg class=\"info\" viewBox=\"0 0 720 420\" role=\"img\" aria-label=\"Key takeaways\"><rect width=\"720\" height=\"420\" rx=\"6\" class=\"svg-dark\"\/><text x=\"28\" y=\"44\" class=\"svg-tw\">Key takeaways<\/text><line x1=\"28\" y1=\"58\" x2=\"120\" y2=\"58\" class=\"svg-line2\"\/><rect x=\"24\" y=\"76\" width=\"336\" height=\"96\" rx=\"4\" class=\"svg-card\"\/><path d=\"M75.3,114.0 L75.3,134.0 L58.0,144.0 L40.7,134.0 L40.7,114.0 L58.0,104.0Z\" class=\"svg-hex2\"\/><text x=\"58\" y=\"130.0\" text-anchor=\"middle\" class=\"svg-n2\">1<\/text><text x=\"90\" y=\"119\" class=\"svg-c\">Reduce irrigation gradually<\/text><text x=\"90\" y=\"139\" class=\"svg-c\">following ETo<\/text><rect x=\"372\" y=\"76\" width=\"336\" height=\"96\" rx=\"4\" class=\"svg-card\"\/><path d=\"M423.3,114.0 L423.3,134.0 L406.0,144.0 L388.7,134.0 L388.7,114.0 L406.0,104.0Z\" class=\"svg-hex2\"\/><text x=\"406\" y=\"130.0\" text-anchor=\"middle\" class=\"svg-n2\">2<\/text><text x=\"438\" y=\"119\" class=\"svg-c\">Bring cycles forward so the<\/text><text x=\"438\" y=\"139\" class=\"svg-c\">leaf dries<\/text><rect x=\"24\" y=\"184\" width=\"336\" height=\"96\" rx=\"4\" class=\"svg-card\"\/><path d=\"M75.3,222.0 L75.3,242.0 L58.0,252.0 L40.7,242.0 L40.7,222.0 L58.0,212.0Z\" class=\"svg-hex2\"\/><text x=\"58\" y=\"238.0\" text-anchor=\"middle\" class=\"svg-n2\">3<\/text><text x=\"90\" y=\"227\" class=\"svg-c\">Check how much rain really<\/text><text x=\"90\" y=\"247\" class=\"svg-c\">enters the soil<\/text><rect x=\"372\" y=\"184\" width=\"336\" height=\"96\" rx=\"4\" class=\"svg-card\"\/><path d=\"M423.3,222.0 L423.3,242.0 L406.0,252.0 L388.7,242.0 L388.7,222.0 L406.0,212.0Z\" class=\"svg-hex2\"\/><text x=\"406\" y=\"238.0\" text-anchor=\"middle\" class=\"svg-n2\">4<\/text><text x=\"438\" y=\"227\" class=\"svg-c\">Detect dry and waterlogged<\/text><text x=\"438\" y=\"247\" class=\"svg-c\">spots now<\/text><rect x=\"24\" y=\"292\" width=\"336\" height=\"96\" rx=\"4\" class=\"svg-card\"\/><path d=\"M75.3,330.0 L75.3,350.0 L58.0,360.0 L40.7,350.0 L40.7,330.0 L58.0,320.0Z\" class=\"svg-hex2\"\/><text x=\"58\" y=\"346.0\" text-anchor=\"middle\" class=\"svg-n2\">5<\/text><text x=\"90\" y=\"345\" class=\"svg-c\">Use autumn to check the system<\/text><rect x=\"372\" y=\"292\" width=\"336\" height=\"96\" rx=\"4\" class=\"svg-card\"\/><path d=\"M423.3,330.0 L423.3,350.0 L406.0,360.0 L388.7,350.0 L388.7,330.0 L406.0,320.0Z\" class=\"svg-hex2\"\/><text x=\"406\" y=\"346.0\" text-anchor=\"middle\" class=\"svg-n2\">6<\/text><text x=\"438\" y=\"335\" class=\"svg-c\">Note every adjustment to<\/text><text x=\"438\" y=\"355\" class=\"svg-c\">compare between years<\/text><\/svg><p class=\"src\">Further reading: <a href=\"https:\/\/www.aemet.es\/\" target=\"_blank\" rel=\"noopener\">AEMET<\/a>.
