Weather guides
How heat, moisture, and forecasts actually work — for your runs and your dog's walks. The running guides cite the published research behind Wyndo's pace math; the dog guides teach the physical checks no app replaces. All of it is informational: not medical advice, not veterinary advice.
Wyndo builds the run scoring, pace calculator, and pavement-heat estimate these guides explain. It can flag concern from current weather, but it cannot measure the ground or examine you or your dog.
Running weather
- Is it too hot to run?
Why there is no single cutoff temperature: WBGT, the race flag system, what heat measurably costs (a cited range) — and when the question stops being about pace.
- Dew point for runners
Relative humidity misleads; dew point does not. The moisture number that sets your cooling ceiling, and how to use it to pick your run.
- Heat acclimatization for runners
What actually changes over one to two weeks of summer running, the fall-marathon angle — and what adaptation cannot do.
- How far out can you trust a race-day forecast?
What a forecast can and cannot tell you at 10 days, 6 days, and 48 hours — and how to stop the taper-week refresh spiral.
Dog-walk heat
- How hot is too hot for dog paws?
Start with the pavement, not the air: how hot ground injures paws, what changes the risk, and when to skip the walk entirely.
- The 7-second hand test, done properly
Back of the hand, a full seven seconds, on the worst stretch of your route — plus what a borderline read feels like and what the test cannot tell you.
- Dog heatstroke signs on walks
The signs to watch for during and after a walk, what to do immediately, which dogs overheat first — and when it is a straight-to-the-vet emergency.
- Pavement temperature vs air temperature
Why a warm-sounding afternoon can mean burn-hot asphalt: solar load, surface differences, why evenings stay hot — and how Wyndo estimates it.
About these guides
- Are these guides medical or veterinary advice?
- No. The running guides explain what heat, moisture, and forecasts do to a run — they are informational, never medical advice or a training plan. The dog guides explain how heat reaches paws and dogs and how to check conditions for yourself — informational, not veterinary advice. For questions about your health or your dog’s, talk to a professional.
- What is the fastest way to check conditions right now?
- For a run, the run planner scores every start time across your range and names the limiting conditions. For a dog walk, use Wyndo’s Paw Check — it reads current weather for the selected location and flags pavement-heat and whole-dog heat concern. It cannot measure the pavement itself, so use the 7-second hand test on the actual surface.
- Where do the numbers in the running guides come from?
- From the same published studies Wyndo’s heat-adjusted pace calculator is built on — each running guide lists its citations at the bottom. Where the research disagrees, the guides show the disagreement as a range instead of picking one number.
- Do the guides give breed-specific temperature thresholds?
- No. There are no per-breed thresholds and no per-breed model — a breed’s size, coat, and flat-faced build can only make warnings come earlier, never later. The breed pages explain exactly what each build changes.
