Housekeeping first: I didn't post a July forecast. June ran long with the World Cup and WWDC stacked on top of each other, July got away from me, and the honest thing is to say so rather than quietly skip a month and pretend the cadence held. So this one grades the June calls, five weeks late, and then makes seven new ones for August.
Twelve years hosting and managing STRs across the South Bay. 1,016 Airbnb reviews, 4.83-star Superhost. The calls come off my own portfolio's booking data, the weekly pulls from PriceLabs and AirDNA, and what guests are telling me about the rest of the summer. I'll grade these on September 1.
How June went
Before the grades, one correction I owe you. I wrote those June calls around "WWDC week, June 9-13." WWDC 2026 actually ran June 8-12, and more importantly it was a primarily online conference with a single in-person day at Apple Park on June 8. I priced and forecast it like the old pre-2020 event that filled Cupertino with thousands of visiting developers for a week. That's not what WWDC is anymore, and building predictions on it was my error, not the market's.
1. Cupertino inventory locks below 5% for the WWDC window, ADR at 2.5-3.0x off-peak. Partial. Cupertino did tighten hard in June and the ADR premium was real, but I attributed it to the wrong driver. With WWDC online-first, the squeeze came mostly from the World Cup matches at Levi's starting June 13 and the intern wave arriving the same fortnight. Right outcome, wrong reasoning, and I'm counting that as half a point at best.
2. Mountain View and Sunnyvale 1BR availability below 10% by June 5 for June 8-21 stays. Hit. The intern surge arrived on schedule and the corridor tightened before the window opened.
3. MTR pipeline for July through September at least 15% above 2025. Hit, and by more than I called. The mid-term side has been the strongest part of my book all summer, which is why I keep pushing hosts to run the numbers on it.
4. San Jose issues 30-50 enforcement notices in June. Incomplete. The city doesn't publish a clean monthly count, and what I can see through my own permit-compliance work doesn't add up to a number I'd stand behind in print. I shouldn't have written a prediction I had no reliable way to score. Dropping this style of call rather than pretending to grade it.
5. No meaningful AB 1482 amendments in June, no new HCD guidance. Hit. Quiet month, as expected for a summer session. Worth flagging for anyone running long-term or mid-term units, though: the statewide rent cap recalculates effective August 1, so check your allowable increase before you send a renewal notice.
6. Cupertino WWDC-week ADR between $480 and $650, 75th percentile above $600. Partial, with the same caveat as the first call. The nightly numbers in that stretch held up, but the demand underneath them was tournament and intern demand, not developers.
7. AirDNA mid-year South Bay report drops June 20-30. Incomplete, same problem as the enforcement call. I don't have a defensible record of the exact publication date, so I'm not going to claim one.
Final: 2 clean hits, 2 partials, 1 hit on the quiet call, and 2 predictions I never should have made because I had no way to score them honestly. That's a worse month than the June scorecard I'd have written for myself five weeks ago, and the fix going forward is that every call has to be something I can measure from my own book or verify from a public source. Predictions I can't grade aren't predictions. They're guesses with a confident font.
August 2026, 7 predictions
1. Labor Day weekend is still unbooked on August 31
Labor Day falls on September 7 this year, so the weekend itself lands outside this forecast window and I'll grade the occupancy in September. What I can grade on August 31 is the booking pace, and I expect it to look like Memorial Day did: national pricing tools treating it as a holiday surge, South Bay guests not showing up for it, because we're a feeder market for Tahoe and the coast rather than a destination.
The call: as of August 31, South Bay units priced at a 25%-plus premium for the September 5-7 weekend are materially less booked than units priced at or near a normal weekend rate.
2. SJSU move-in drives a mid-August spike, and Stanford's is next month
These two campuses are on completely different calendars, and treating them as one back-to-school event is how hosts misprice the month. SJSU is on semesters and classes start August 19, so move-in and family travel land the weekend before. Stanford is on quarters, with move-in September 15 and classes September 22, which puts its demand in next month's forecast entirely.
The call: whole-home units within 15 minutes of SJSU clear 1.5-2.0x their August base rate for the August 14-18 window, while units near Stanford see no comparable August lift.
3. Leisure demand falls off after the third week
Bay Area school districts start mid-to-late August, and family leisure travel stops the moment it does. Weeknight business travel starts filling back in over the same stretch.
The call: leisure-attributed bookings in my portfolio drop at least 25% in the last ten days of August versus the first ten, while weeknight occupancy holds flat or rises.
4. Mid-term keeps taking share
With nightly softening into the shoulder, the 30-plus day booking is the cleanest way to protect September and October. I expect the mix to keep shifting.
The call: 30-plus day bookings account for at least 35% of new reservations I take in August, up from the summer run rate.
5. September fills faster for the units that reset early
This is the one I most want to be able to prove, because it's the whole argument behind repricing in August rather than September. If the reset works, the units that did it should carry visibly more September occupancy on the books by month end.
The call: on August 31, units in my portfolio that completed the fall pricing reset by August 15 show at least 15 percentage points more September occupancy on the books than units that hadn't reset by then.
6. At least one PSPS event touches South Bay inventory
August is when the fire-weather pattern usually starts producing shutoff warnings, and a de-energization in the hills affects hosts on the western and southern edges of the market.
The call: PG&E issues at least one PSPS warning or event affecting Santa Clara or San Mateo county service areas before August 31.
7. Pricing tools flip to fall mode by the last week
The seasonal recalibration is mechanical, and every major tool makes the same move within a few days of each other.
The call: by August 25, the major dynamic pricing tools have dropped South Bay September base rates at least 8% off their August levels.
What could move these calls
A late heat dome would push leisure demand later into August than I'm calling, and would also raise the odds on the PSPS prediction.
A surprise Fed move at the September meeting could firm business travel earlier than usual, which would show up in weeknight bookings in the final week.
Any real movement on state or city STR rules would reset the enforcement call entirely, though nothing is pending that I'd expect to land this month.
How to use this
The single highest-value action this month is not repricing August. It's repricing September. The shoulder-season reset covers the specific settings, and the window to make those changes closes as August does.
If you're near SJSU, load August 14-18 manually right now. Tools underprice campus move-in the same way they underprice every local event, and on that corridor it's the best revenue in the month. If you're near Stanford, hold that powder until September.
And if your occupancy is soft through September, run the mid-term math before you start discounting nightly. One 30-day booking beats a month of half-filled calendar at a lower rate.
September 1 grading.
