Akiva’s Walking Forecaster
If you have a dog, you know the summer ritual: you stand at the door on a hot afternoon, look at the sidewalk, and try to guess whether it’s too hot for their paws. Maybe you’ve heard the trick: press the back of your hand to the pavement, and if you can’t hold it there for seven seconds, it’s too hot to walk. It’s a good test. But it only works if you’re already outside, standing on the pavement, deciding in the moment.
I always wanted to know before I got Akiva, my old Shih Tzu, all excited about a walk. And every “is the pavement hot?” guide online is just a static picture: the same chart for Phoenix and for Wisconsin in October. So I built a tool that actually does the math, for right now, where you live. It’s called Akiva’s Walking Forecaster:
It actually computes the pavement temperature
This is the heart of it, and it’s not a lookup table. For every hour in the forecast, the tool figures out where the sun is in your sky, estimates how much sunlight is reaching the ground, dims that for the cloud cover in the forecast, and then heats the pavement above the air temperature the way real asphalt does, calibrated against published readings (77°F air can mean ~125°F asphalt; 87°F air, ~143°F). Then it translates that number back into something human: the same place where the seven-second hand test turns into a one-second one.
The whole picture, hour by hour
Heat is only one way a walk goes wrong, so it weighs the rest too: the heat index when it’s humid, wind chill when it’s cold, the air-quality index, and rain. Each hour gets a simple verdict (Good, Care, Wait, or No), and the verdict is the worst factor for that hour, not an average. One genuinely dangerous number is enough to skip it. You get a strip of the next 24 hours at a glance, and the tool calls out your actual walk windows: “good until 10am, then again after 7pm.”
Tuned to your dog, not a generic one
A husky and a greyhound do not experience the same afternoon. So you tell it about your dog (size and coat) and pick the surface you actually walk on (dark asphalt runs a lot hotter than a shaded dirt trail). Got more than one dog? Add them all and switch between them.
All it needs is a ZIP code
No app to install, no account required. Type in your ZIP and you get your report. If you want, you can sign in to sync your dogs across your phone and laptop, but that’s entirely optional. And there’s no ads and no tracking: the forecast math runs right in your browser, the weather comes from the National Weather Service, and the air quality from Open-Meteo. No API key, nothing for sale.
One honest note
A forecast is still a forecast, and the pavement estimate is good to about ±5°F. So treat it as a smart heads-up, not gospel: when you’re actually out there and in doubt, do the real hand test. You can also save a little image of today’s walk window to check at a glance or share with whoever’s walking the dog next.
It’s named for Akiva, but it works for any dog. It’s free and it’s right here:
