How the Dog Comfort Index is calculated

The Dog Comfort Index (0–10) is our own, educational estimate calculated locally from current weather data — not a clinical or scientifically established method. The score starts at 10 and is reduced step by step depending on how conditions are judged to affect an average dog:

• Perceived temperature – the largest deduction for intense heat (≥ 26–30°C / 79–86°F) and severe cold (≤ −8 to −15°C / 18 to 5°F), a smaller deduction for milder heat or coolness.
• Humidity – high humidity combined with heat makes conditions more strenuous and lowers the score further.
• Precipitation – rain or wet snow leads to a deduction that increases with the amount.
• Snowfall – a smaller deduction, partly for the risk of snow and ice getting stuck between the paw pads.
• Wind and gusts – strong gusts cause the largest deduction, moderate wind a smaller one.

The score maps to the levels Excellent, Good, Okay with some adjustments, Take it easy, and Unsuitable for longer activity, along with the conditions that contributed most and a short piece of advice. The same index is also used hour by hour in "Best walk time right now", where the coming hour with the highest score is highlighted, as well as a daytime average for each day in "Upcoming days" — click a day there to see the times of day behind the average. Your dog's breed, size, age, health, coat, fitness and individual tolerance always affect what's actually suitable, and the index never replaces a vet's judgement.
