The November Flip And The Sole You Chose In August
November 19, 2025 · Nayeli Cordero · Seven minute read
The bare ground patch took a divot on Tuesday for the first time since the second week of July. It is not a dramatic event and nobody else in the shop noticed, but I write the date down every year because it is the most useful line in the plot condition log.
Central Valley golf is played on two different surfaces that happen to share a postcode. There is the dry ground, which runs from roughly May to October and is firm, thin and unforgiving. And there is the wet ground, roughly November to March, which is soft, overseeded and grabby. The transition between them takes about three weeks in each direction.
What makes this worth an entry in the journal is that the club properties which are correct for one half are frequently wrong for the other, and almost nobody accounts for it because equipment decisions get made once and then left alone for four years.
What actually changes underfoot
Three things, and they do not move in lockstep.
Surface hardness goes first. The rain arrives, the crust softens, and within days the ground will accept a leading edge that it was rejecting the week before. Then the overseed comes through, which on most courses in this area means perennial rye drilled into dormant bermuda, and suddenly there is a cushion of new growth sitting on top of the softening base. Last, and slowest, the collars thicken up, because kikuyu keeps growing later into the year than anything around it.
So for two or three weeks in November you are playing a hybrid surface: soft underneath, thin on top, thick at the edges. It is the single hardest condition to fit for and it is why we do not run full ladder sessions in the middle of the change if we can avoid it.
A sole is not correct or incorrect. It is correct for a firmness, and firmness in this valley is a seasonal variable with a range wider than most people's entire equipment budget.
The trap, stated plainly
Somebody gets fitted in August. The plot is baked, the bare ground rung is punishing, and the candidate that survives it is a narrow sole with modest bounce and a leading edge that sits low. It is genuinely the right club for that ground and the ladder card says so in four columns.
December arrives. The same golfer is now taking sod out of soft overseed, the narrow sole is cutting into ground that offers no resistance, and every approach is coming up short and heavy. He concludes that the fitting was wrong, or that his swing has fallen apart, and both conclusions are incorrect.
| Reading | August, firm | January, soft |
|---|---|---|
| Narrow sole, speed held rung 2 | 98 | 89 |
| Narrow sole, typical mark | Short comma | Long smear, bruised front |
| Medium sole, speed held rung 2 | 94 | 96 |
| Medium sole, typical mark | Slight chatter | Short comma |
Neither club is bad. They are correct at different times of year, and the gap between them is large enough to be worth a shot or two a round in each direction.
What we actually recommend
Not two sets of irons. That is an absurd amount of money for a seasonal advantage and Arman is right to keep saying so, even when I am arguing the other way.
What we do instead, in order of how often we recommend it:
- Fit the irons for the ground you play most. For nearly everybody in this valley that is the dry half, because the golf season here is functionally eight months long and five of those are firm. Accept that December will be slightly awkward.
- Carry the seasonal variation in the wedges instead. Wedges are where the ground does the most damage and they are individually affordable. A second fifty-six with a wider grind, swapped in for the wet months, solves most of the problem for a fraction of what a second set costs.
- Book the recheck. An hour on rungs one and four with your existing clubs in late October or mid March, sixty dollars, and it catches both the seasonal issue and any lie drift that has crept in since the last visit.
- Change the ball before you change the clubs. Soft ground rewards a different spin profile than firm ground and it is a two dozen decision rather than a two thousand dollar one. Genuinely worth trying first.
Why the card carries both
Every ladder session run here records the plot condition on the day, and Arman keeps a correction table built from nine years of running the same clubs on the same four patches through both halves of the year. So a card written in August also carries an estimate of what those numbers become in January, and vice versa.
It is an estimate and it is labelled as one. But it turns the seasonal swap decision from a guess into a five minute conversation, and it means that when somebody rings in December saying everything has gone wrong, we can usually tell them what happened without them driving over.
The date in the log
First divot from the bare patch: November 18 last year, November 24 the year before, November 9 in the wet winter of 2023. Last dry-out, which is the other end of the same measurement: May 22, June 1, and May 14 respectively. If you want to know when to swap your wedge, that six-week window either side of those dates is the honest answer.
One thing not to do
Do not bend your lofts to chase the season. It comes up perhaps twice a year, usually from somebody who has read that a degree of loft is worth some number of yards, and it is a bad idea because loft is not the variable that changed. The ground changed. Bending a set twice a year to compensate for a sole problem introduces wear on the hosels and solves nothing, and we will decline to do it.
