Why My Denver Budget Fell Apart in June—And It Wasn't the Housing Market
Marcus Thompson
I sat down at my kitchen table on the first Sunday of July with my laptop, a cup of coffee, and the sinking feeling that something had gone wrong with my finances. I'd been tracking every dollar since January. I had spreadsheets. I had categories. I had a color-coded system that would make an accountant weep with joy. And yet, at the end of June, I was $340 over budget. Not on rent. Not on my car payment. Not on anything I could have predicted. I was over budget on electricity, groceries, water, and what I had vaguely labeled "home supplies." I stared at the numbers for an hour, trying to figure out where I'd failed. Then I checked the weather data for Denver in June 2026. Fifteen days over 90°F. Seven consecutive days over 95°F. Three days that hit 101°F. And I realized I hadn't failed. The climate had changed, and my budget—like my apartment—wasn't built for it.
I moved to Denver five years ago from Chicago. Everyone told me the weather was perfect. "Dry heat," they said. "You'll love it." And I did, for the first three years. The summers were warm but manageable. My electric bill in July 2023 was $87. My electric bill in July 2025 was $112. My electric bill estimate for July 2026, based on the first three weeks, is going to be somewhere around $180. That's a 107% increase in three years. Not because I'm using more electricity for fun. Not because I bought a hot tub. Because I now run my window air conditioner for 10 to 12 hours a day instead of 4 to 6. Because I run fans in every room. Because I have a dehumidifier running in the basement because the heat is causing moisture problems I never had before. My apartment doesn't have central air. It was built in 1987, when Denver summers were mild enough that a swamp cooler and some fans were sufficient. That Denver doesn't exist anymore.
The grocery bill was the real shock, though. I tracked it carefully. I buy essentially the same things every week. Chicken, rice, vegetables, eggs, bread, coffee, some snacks. In March, my average weekly grocery bill was $94. In June, it was $127. That's a 35% increase in three months. I thought I was buying more expensive items. Maybe I was stress-eating. Maybe I was being less disciplined. But then I looked at the receipts. The chicken was the same price. The rice was the same price. The vegetables... well, the vegetables had changed. Tomatoes that were $2.49 a pound in March were $4.19 in June. Lettuce that was $1.99 a head was $3.49. Berries were basically gold-plated. I asked the cashier at my King Soopers what was going on. She shrugged and said "supply chain issues." I asked another cashier. She said "the heat in California." Both were right, and both were incomplete. The heat dome that sat over the Central Valley in June destroyed crops. The wildfires in Oregon and Washington disrupted distribution. And the increased refrigeration costs for stores trying to keep produce from spoiling in the heat got passed on to me, standing in the checkout line with a basket of overpriced vegetables and a growing sense of financial dread.
I started researching what climate change is doing to household budgets. Not the big macro stuff—insurance premiums, disaster recovery, infrastructure costs. The small, personal stuff. The stuff that shows up in your monthly spreadsheet and makes you wonder if you're bad with money. The answer is that heat is expensive. It's expensive in ways that don't show up in the headlines. Your electricity bill goes up because you're running the AC more. Your water bill goes up because you're showering twice a day and watering your garden more to keep it from dying. Your grocery bill goes up because heat destroys crops and disrupts supply chains. Your home maintenance costs go up because heat causes materials to expand and crack and fail in ways they didn't used to. Your health costs go up because heat stress is real and it sends people to the emergency room. And none of this is captured in the official inflation numbers, which tell us that inflation is "moderating" at 3.2%. The inflation numbers don't know that my tomato budget has doubled. They don't know that my electric bill is breaking records. They measure a basket of goods that assumes a stable climate, and the climate is not stable.
I tried to adjust my budget. I created a new category called "climate adaptation." It includes the extra electricity, the extra water, the higher groceries, the $60 I spent on blackout curtains for my west-facing windows, the $45 I spent on a better fan, the $30 I spent on a portable mister that I now regret because it just made my apartment humid. The "climate adaptation" category in July is $340. That's more than my car insurance. That's more than my internet and phone combined. That's a category that didn't exist in my budget five years ago, and now it's one of my largest discretionary expenses. And it's not discretionary. It's survival. I can't not pay it. I can't decide to just be hot and hungry instead. Well, I could, but my employer prefers that I show up to work not drenched in sweat and hallucinating from heat exhaustion.
The water bill was another surprise. Denver Water charges in tiers. The first tier is cheap. The second tier is more expensive. The third tier is where they start punishing you. In June, I hit the third tier for the first time in my life. I used 12,000 gallons. My normal summer usage is around 7,000. The difference was my lawn. I know, I know. Lawns are bad. Xeriscaping is better. But I rent. I don't own the lawn. I can't tear it out and replace it with native grasses. My landlord expects me to maintain it, and maintaining it in 100-degree heat requires water. A lot of water. I tried letting it go brown. My landlord left a note. "Please maintain the landscaping per your lease agreement." So I watered. And I paid. And my budget took another hit that I couldn't have predicted in January when I was making my annual financial plan in a 65-degree apartment with a clear head and optimistic assumptions about the future.
I started talking to my neighbors about this. The guy in 3B, a teacher who makes about what I make, told me he's been putting his groceries on a credit card since May because his paycheck doesn't stretch far enough anymore. The woman in 2A, a retired nurse on a fixed income, told me she had to choose between running her AC and buying her medications. She chose the medications. She sits in her apartment with a wet towel around her neck and a fan pointed at her face. She's 74. She shouldn't have to make that choice. But she does, because the cost of staying cool has outpaced the cost of living adjustments in her Social Security payments. The inflation numbers say 3.2%. Her reality says 15% for anything related to surviving the summer. Those numbers don't match because the official numbers weren't designed to measure climate-driven cost increases. They were designed for a world where the weather was a background variable, not a primary driver of household expenses.
I tried to find resources for this. I looked for budgeting advice that addressed heat-related cost increases. I found articles about "summer energy savings" that suggested things like "open your windows at night" (the air quality is bad from wildfires), "use a programmable thermostat" (I don't have one, and my landlord won't install one), and "wear lightweight clothing" (I'm already in my underwear, thanks). I found articles about "eating healthy on a budget" that suggested seasonal produce (the seasonal produce is either destroyed by heat or too expensive to buy) and bulk grains (which I already buy, and which don't make up the cost difference when tomatoes are $4 a pound). The financial advice industry, like the fitness wearable industry, is built on assumptions about environmental stability that no longer hold. They don't know what to tell you when your budget is being destroyed by the thermometer.
So I started building my own system. I took my historical spending data from the past three years and overlaid it with temperature data. The correlation was undeniable. Every degree above the monthly average added approximately $8 to my electricity bill and $4 to my grocery bill. At 5 degrees above average, I was looking at an extra $60 a month. At 10 degrees above average, it was $120. This summer, June was 8 degrees above average. July is tracking at 12 degrees above average. That's an extra $100 to $150 per month that I didn't budget for because I didn't know I needed to. And next year might be worse. The year after that might be worse still. I'm not budgeting for a stable climate anymore. I'm budgeting for a climate that is actively hostile to my financial stability.
I started a "heat emergency fund." It's separate from my regular emergency fund. The regular fund is for job loss, medical emergencies, car repairs. The heat fund is for the extra costs that come with every heat wave. I put $100 a month into it during the cooler months so I have a buffer when the summer hits. It's not enough. It won't cover a really bad July. But it's something. And it acknowledges the reality that my expenses are no longer predictable based on historical patterns. The past is not a guide to the future when the climate is changing this fast.
The psychological toll is harder to quantify than the financial one. I used to enjoy budgeting. It felt like a game. Optimize the categories, find the savings, watch the net worth grow. Now it feels like a defensive operation. Every month is a battle against forces I can't control. The heat comes. The bills go up. I cut something else to compensate. Last month I cut my gym membership. The month before, I cut my streaming subscriptions. Next month, I don't know what I'll cut. Maybe I'll start eating rice and beans for dinner. Maybe I'll start taking cold showers exclusively, which would at least save on the gas bill. The point is that I'm not optimizing anymore. I'm surviving. And survival budgeting is not fun. It's stressful. It's demoralizing. It makes you feel poor even when you're not, because you're constantly making hard choices about basic necessities.
I'm angry about this. I'm angry that I live in a country where the official economic statistics don't capture the reality of climate-driven cost increases. I'm angry that my landlord won't install central air because "it's not in the budget" while I'm paying record electric bills to keep his apartment habitable. I'm angry that grocery stores can raise prices by 50% on staple vegetables and call it "market forces" when the real force is a heat dome that destroyed the supply. I'm angry that I'm supposed to be the one who adapts, who cuts back, who finds a way to make it work, while the systems that created this problem roll on unchanged. I'm not a climate scientist. I'm not a policy maker. I'm a guy in Denver with a spreadsheet and a window unit that runs constantly and still can't get the bedroom below 78 degrees at midnight.
But I'm also practical. I'm not moving back to Chicago. The winters there are brutal, and the summers are getting hot too. There's no escape from this. There's only adaptation. So I run my budget hotter than I used to. I build in buffers I didn't need before. I track the "climate adaptation" category like it's rent, because it basically is. And I tell everyone I know to do the same. If you're in Denver, or Austin, or Portland, or anywhere else that's been baking this summer, check your budget. Look at your electricity, your water, your groceries. I bet you'll find a heat tax that nobody warned you about. It's not your fault. It's not poor planning. It's the new cost of living in a world that's getting hotter, and our budgets need to catch up before our finances melt down along with the ice caps.
How are you adjusting your budget for the heat? Because I'm starting to think "climate adaptation" needs its own line item in every personal finance app on the market.
The thing that really broke my spirit was the realization that I was budgeting for a fantasy. Every personal finance book I've ever read—Ramit Sethi, Dave Ramsey, the FIRE community—they all assume a stable environment. They assume that your biggest variable is your own behavior. That if you just optimize enough, cut enough, save enough, you'll be fine. They don't account for the climate. They don't account for the fact that your "discretionary" spending is being eaten by forces outside your control. They don't account for the $340 that appeared in my budget like a ghost, haunting every category, every calculation, every dream of financial independence. The advice is not wrong. It's just incomplete. It's like giving someone a map to a treasure chest and not mentioning that the island is sinking.
I started talking to my coworkers about it. The woman in accounting, who has three kids, told me her family's summer expenses had increased by $800 a month. The AC in their house runs constantly. The kids are home from school, eating more. The pool membership—formerly a luxury—is now a necessity because it's the only place the kids can be outside without getting heat sick. The groceries are up. The water bill is up. The gas bill is up because she's driving the kids to air-conditioned places instead of letting them play in the yard. She's not living beyond her means. She's living within the means of a climate that demands more. And her budget, like mine, is cracking under the strain.
I'm not giving up on budgeting. I'm not giving up on tracking. I'm not giving up on the dream of financial stability. But I'm giving up on the illusion that I can control everything. The climate is a variable now. A big one. And my budget has to reflect that. So I track the heat. I track the bills. I track the "climate adaptation" category. And I adjust. Every month. Every season. Every year. Because the old rules don't work anymore. And the sooner we admit that, the sooner we can build new rules that actually help us survive.
