2026 John Deere Classic Weather Forecast: Daily Wind, Rain, and Betting Outlook

The 2026 John Deere Classic weather forecast points to dangerous heat and midweek storms rather than wind at TPC Deere Run in Silvis, Illinois. Round 1 Thursday stays dry but broils, with afternoon feels-like readings above 100 degrees, before a wet Friday through Sunday stretch brings storms, possible delays, and softer greens. For scoring and betting, that shapes up as a gettable, birdie-friendly week.

The forecast models broadly agree on the oppressive heat and the light wind, and their main disagreement is the timing and the amount of rain from Friday onward. Expect a low-scoring event where afternoon storm exposure, not a stiff breeze, is the biggest variable for tee-time planning.

Thursday: Round 1 Weather (July 2)

Round 1 Thursday is all about the heat, with a daytime high near 98 degrees and afternoon feels-like values climbing above 100. Wind stays modest out of the southwest at 4 to 15 mph, so it will not defend the course, and rain is a non-factor at just a 10% chance. Early starters get the more bearable window, while the afternoon wave grinds through the peak heat and humidity.

Friday: Round 2 Weather (July 3)

Friday is the washout risk of the week, with storms likely across the playing window and a rain chance around 65%. Highs still reach the low 90s under heavy humidity, and a late surge of gusts toward 31 mph signals a storm threat rather than a steady breeze. A delay or a lost stretch of holes is a real possibility, and any rain that lands only softens an already receptive setup.

Saturday: Round 3 Weather (July 4)

Saturday brings scattered Independence Day storms and the week’s gustiest morning, with early gusts to 27 mph out of the south. It stays hot and humid with a high near 90 and a rain chance close to 59%, so the threat is a passing cell and a possible delay rather than an all-day washout. Morning groups face the breeziest air before the wind settles in the afternoon.

Sunday: Final Round Weather (July 5)

The final round turns cooler behind a wind shift to the north, though a wet morning greets the early groups before the rain eases. The rain chance runs near 64% early and falls toward the mid 20s by the afternoon, and highs back off to the mid 80s with a gentle 4 to 10 mph breeze. Once the showers clear, it is another benign, low-scoring setup for the closing stretch.

Betting and DFS Outlook

The weather story at the 2026 John Deere Classic is heat and soft turf, not wind. Sustained wind barely cracks the mid teens on the breeziest morning and sits in single digits for much of the week, so the ability to handle a stiff wind is close to irrelevant here. Pair that with a low-scoring track and a Friday-through-Sunday storm risk that can drop enough rain to soften the greens, and the setup rewards aggressive, birdie-heavy profiles over grinders. The one edge worth tracking is tee-time storm exposure, since the Friday and Saturday afternoons carry the higher delay risk.

Translate that into your own read rather than a blanket pick. If you build a model with strokes gained data, lean the weighting toward approach play and birdie-or-better rate for a gettable, receptive TPC Deere Run, and treat the storm chances as a scoring-softener rather than a true course defense. The models agree on the heat and the calm, and most of the spread sits in the rain odds, so watch how Friday through Sunday firm up before you lock in positions.

Before they tee off, build your model. The Rabbit Hole hands you the strokes gained PGA data, and code BSG26 takes 25% off any plan.
