My wife found my weather spreadsheet at 2 AM on a Saturday.
"Honey... why do you have a file called 'Workshop Weather Patterns Final FINAL v3'?"
I tried to explain. She laughed. Then she looked closer.
"Wait, is this showing that rain increases revenue by 20%?"
"Technically, mild rain. Severe storms are terrible. There's a sweet spot between—"
"You're serious about this."
"Dead serious. Look at workshop 247. Thunderstorm warning, 31 attendees, $38,000 revenue. Best event ever."
She stared at me like I'd joined a weather cult.
How It Started
It began innocently. Dr. Martinez called to cancel her workshop because of a forecast for "beautiful weather."
"Everyone will be outside," she said. "Nobody wants to sit in a seminar on the first perfect spring day."
I told her she was overthinking it. Run the workshop.
Seven people showed up. Her previous workshop, during a dreary February drizzle? Twenty-two people.
That night, I started a spreadsheet.
The Obsession Grows
First, I just tracked sunny vs. rainy. Then I got specific:
- Temperature (exact)
- Precipitation (type and amount)
- Cloud cover (percentage)
- Wind speed (because why not)
- First nice day of spring (kiss of death)
- First snow (surprisingly good)
My team thought I'd lost it. "We're marketers, not meteorologists," they said.
But the patterns... the patterns were beautiful.
The Goldilocks Zone Emerges
After 200 workshops, clear winners emerged:
Best Weather for Attendance:
- 55-70°F (not too hot, not too cold)
- Overcast or light rain
- Mild wind (under 10mph)
- Stable conditions (no dramatic changes)
Worst Weather for Attendance:
- Perfect sunny days (75°F and clear)
- First nice day after winter
- Holiday weekends with good weather
- Extreme anything
The correlation was embarrassingly strong. r=0.73 for you statistics nerds.
The Day I Became a Believer
Workshop 341. Dr. Chen in Portland.
I suggested March 15th. She wanted March 22nd. I checked the historical weather data (yes, I do that now).
"March 15th has a 70% chance of light rain. March 22nd is typically sunny. Take the rain date."
She thought I was insane but trusted me.
March 15th: Drizzle. 26 attendees. $31,000 revenue. March 22nd: Gorgeous. Her competitor ran a workshop. 9 attendees.
Dr. Chen now asks for my weather predictions before scheduling anything.
The Seattle Revelation
Our Seattle practices averaged 24 attendees. National average: 15.
"What's your secret?" I asked.
"Secret? It rains here 200 days a year. Every day is workshop weather."
That's when it clicked. Seattle doesn't have perfect weather to compete with indoor events. Every day is mild-bad-weather day.
Mind. Blown.
The Confession
Here's the embarrassing part: I now check 10-day forecasts before confirming workshop dates.
Not obsessively. Just... strategically.
Okay, obsessively.
I have weather apps from three different services. I compare historical patterns. I've memorized microclimates in major markets.
My wife bought me a weather station for Christmas. As a joke. I use it daily. Not as a joke.
The Business Case (How I Justify This Madness)
Bad weather workshops average:
- 20% higher attendance
- 15% better conversion
- 32% more revenue
That's $3,840 extra revenue per workshop. Times 300 workshops per year = $1.15 million in additional revenue.
Suddenly my weather obsession seems less crazy, right?
...Right?
What This Really Means
Look, I know tracking weather for marketing seems insane. But here's what it taught me:
Success hides in the details everyone else ignores.
While competitors fight over Facebook algorithm changes, we're scheduling workshops during drizzle. While they chase perfect venues, we're booking dates with overcast forecasts.
The best competitive advantage? Caring about variables nobody else measures.
Even if it makes you look weird at parties.
The Text That Made It Worth It
Last week, Dr. Thompson texted: "Scheduled my workshop for the rainy week like you suggested. Highest attendance ever. You're either a genius or a witch."
I'll take either.
But between you and me? I prefer "Revenue Meteorologist."
P.S. - My wife now checks weather before planning anything. "If Garry's right about workshops and rain, maybe he's onto something." Victory tastes like validation.
