The Six-Minute Method
Most golfers waste 20 minutes on Friday night staring at five different weather apps trying to decide if Saturday is a go. The decision is almost always already made by the data — it just needs to be read in the right order. This post walks through the six-minute decision tree we use ourselves, and that golfers use after subscribing to our G-Score alerts.
If you only do one thing differently next Saturday, do this: read the G-Score first, the temperature second, and ignore the radar until the morning of. Most rounds get cancelled because of phantom rain that never falls. The score already accounts for that.
Step 1: Pull the 7-Day Grid (60 Seconds)
Open the course page for your top-choice course. Scroll to the 7-Day Forecast strip at the top of the dashboard. You see seven cards, today through six days out, each with a single G-Score number. That is the weekly playability roadmap.
Look at Saturday’s number. Three possibilities:
- Saturday is the highest score in the week: book Saturday. Decision essentially made. Skip to Step 4 to pick the hour.
- Saturday is within 5 points of the weekly high: book Saturday. Five G-Score points is rounding noise once you factor in microclimate variability.
- Saturday is more than 10 points below another day in your available window: consider moving. If your only flexibility is Saturday, proceed to Step 2 to read the dominant variable.
This step alone eliminates 60 percent of weekend tee-time agonizing. The 7-day grid is the answer to most rounds.
Step 2: Read the Dominant Variable (60 Seconds)
Click into Saturday on the course page. The Live Conditions card shows temperature, wind speed, condition (clear / clouds / rain / mist), and the G-Score. Below it the Performance card breaks down distance impact and wind adjustment in clubs.
Identify which input is suppressing the score. Reference the methodology from our feels-like temperature, rain probability, and altitude deep dives if you want the full physics.
If wind is the dominant variable: the round is still on, but tee-time selection matters more than usual. Wind almost always builds through the day — morning rounds avoid the worst of it. We documented this with hour-by-hour data in our morning vs afternoon analysis. Go early.
If temperature is the dominant variable: the answer depends on whether it is too cold or too hot. Cold means delay until 11am to let the dew burn off and the air warm. Hot means tee at sunrise and finish before 11am. The summer survival guide has the full hydration and pace plan.
If rain is the dominant variable: open the radar and check whether the rain window is in the morning or afternoon. Rain is the only variable where the radar in the morning of beats the forecast.
If multiple variables are pushing simultaneously: the round may not be worth it for a serious score. See Step 6 for the move-or-stay logic.
Step 3: Compare to Your Backup Course (60 Seconds)
You probably have a shortlist of two or three courses. Pull the same Saturday G-Score for each. Most golfers skip this step and play their default course on autopilot. Don’t. A 78 G-Score at your backup course is a better day of golf than a 65 at your home course.
The site’s search bar accepts course names directly — type the name, hit enter, scroll to the 7-day forecast. Same workflow as Step 1, just for the alternative.
If the alternatives are within 5 G-Score points of each other, default to the one you already booked or the one closer to home. Drive time decays the goodwill of a marginal weather upgrade fast.
Step 4: Pick the Hour (90 Seconds)
This is where the highest leverage hides. The hourly G-Score view inside the day breaks Saturday into fourteen one-hour blocks (6am through 8pm in most regions). Find the highest contiguous four-hour block. That is your ideal start window.
Most days, the morning blocks are 8 to 12 G-Score points higher than the afternoon. The reason: wind builds through the day on most US weather patterns, and afternoon UV strain compounds with heat. Mornings are systematically better for golf in the United States. Our data confirms this across hundreds of measured rounds.
Exceptions:
- Coastal courses with marine layer: the fog can sit on the course until 10am. Tee at 11am and you skip the fog without losing the morning calm.
- Cold mornings (below 50°F): the first hour after sunrise is brutal on flexibility. Delay until 9 or 10am to let the air come up.
- Strong afternoon storms forecast: tee even earlier than usual to be off the course before lightning risk peaks.
Step 5: Cross-Check the Wind Direction (60 Seconds)
The G-Score factors wind speed but not direction. Direction matters at certain courses. Pebble Beach plays dramatically differently with a southerly versus a westerly. Bethpage Black has prevailing northwesterly that compounds the back-tee distance. Whistling Straits is exposed in every direction and the wind shifts during the round.
If you know the course, you know the holes that play into the prevailing wind. If you don’t, our PGA wind strategy walks through how tour caddies read direction and adjust on the fly.
Step 6: The Move-or-Stay Logic (90 Seconds)
You’ve gone through Steps 1 through 5 and you’re still ambivalent. Saturday is a 65 G-Score, the dominant variable is wind, your backup course is also a 65, and the alternative day is a 78 but you’re not sure if you can rebook.
The decision rule:
- Casual round / family round / playing for the day itself: a 65 is fine. Adventurous wind is part of the experience. Stick with Saturday.
- Serious score-chasing round / handicap-sensitive / tournament prep: if the alternative day is 75+ and rebookable, move it. A 65 G-Score round is going to add 4 to 8 strokes you wouldn’t add at 78. That is the difference between hitting your target score and having a frustrating Saturday.
- Tournament round (no flexibility): play it. The G-Score isn’t telling you to skip; it’s telling you to recalibrate expectations and gear up. Bring the windbreaker, club up two on every approach, lean on short game.
- Any G-Score below 50: consider hard whether the round is worth it. Below 50 means a dominant variable is at a safety threshold (storm risk, sustained 25+ mph wind, freezing temp). The round will be memorable but not for scoring.
The Six-Minute Workflow Recap
- Step 1 (60s) — Saturday’s G-Score on the 7-day grid. Top of the week or close to it? Book.
- Step 2 (60s) — Click into Saturday. Identify the dominant variable.
- Step 3 (60s) — Compare to backup course G-Score. Within 5 points = stick.
- Step 4 (90s) — Hourly view. Pick the highest-score four-hour window.
- Step 5 (60s) — Wind direction check. Adjust strategy by hole.
- Step 6 (90s) — Move-or-stay calibration if score is below 70.
Total: six minutes, and you have a round, a course, an hour, and a strategy. The rest of Friday night is yours.
Five Tee-Time Picking Mistakes Worth Avoiding
Mistake 1: Booking on the wrong day of the forecast cycle
Most weather apps update the 7-day forecast on a 24-hour cycle. If you check the forecast on Tuesday for the upcoming Saturday, you are reading a relatively unreliable model output. Wait until Thursday for any decision you can defer that long — the 48-hour forecast is dramatically more accurate than the 96-hour.
Mistake 2: Trusting the radar more than the forecast
Live radar is a snapshot of the next 60 minutes. It is not a forecast. We see golfers cancel rounds on Friday night because the radar shows storms over the course at that moment, when those storms will have moved 200 miles east by Saturday morning. Trust the G-Score for the day, the radar for the hour-of.
Mistake 3: Optimizing for marginal weather upgrades at distant courses
Driving 90 minutes to gain 5 G-Score points is a tax on the round, not a benefit. The drive itself depletes the goodwill that the higher score is supposed to deliver. Stay within 30 minutes of home unless the score gap is 15+.
Mistake 4: Ignoring the dominant variable when picking gear
You picked the day, you picked the hour, you forgot to check whether wind, rain, or cold is the variable in play. Your bag should change based on the variable, not based on whether you generally pack rain gear. The dominant variable is on the course page in plain English.
Mistake 5: Letting the spouse make the call by checking iPhone weather
iPhone weather is built for picnics. iPhone weather will tell you Saturday is “sunny, 70” and the round will be sustained 22 mph wind. Use the G-Score for the call, then translate to civilian terms ("the score says it will be a good day with adjustments”) afterwards.
Saturday Morning Workflow on the Day Itself
The decision tree above runs Friday night. Saturday morning has its own short workflow:
- Check the radar at 6am. Confirm no overnight surprises. If radar shows storms inbound that weren’t in the forecast, delay or cancel.
- Re-pull the hourly G-Score. The forecast updates overnight. If the morning hours have shifted up or down, adjust your tee time.
- Pack for the dominant variable. Cold-wind day = layers and a windbreaker. Hot-sun day = electrolytes, sleeves, a lid. Wet day = waterproof gloves, towel, rain gear.
- Leave 15 minutes earlier than you think. Range time matters more on a low-G-Score day — you are going to need the warm-up to reset your swing for the conditions.
The Calmest Course in the Country, Hour by Hour
For golfers with full schedule flexibility, our state landing pages now surface the playable months and dominant climate variable for every state. California coastal courses are the only US courses that consistently sit above 80 G-Score year-round. Florida in the November to April window is similar. Wisconsin peaks in June and July. Arizona December through March is destination-grade.
If you are planning a golf trip rather than a single round, our best golf weather states piece ranks every state by average G-Score across the year. The methodology and data are spelled out so you can see how the rankings were computed.
Bottom Line
Tee-time selection should not take an hour. Six minutes, six steps, one number per step. Read the G-Score first, the dominant variable second, the hourly grid third. Compare to one backup course. Pick the hour. Translate the dominant variable into your gear. Done.
Most rounds golfers regret are rounds where the data said something the golfer ignored. Most rounds golfers love are rounds where they planned around the conditions instead of fighting them. The tools are on the page. The next round is yours.
