Fetching live weather data
The best way to know is to check your local forecast before you wash. If rain is likely in the next day or so, it's usually worth waiting — a wash followed by rain wastes your time and money. SparkDry checks your local weather and gives you a simple WASH or WAIT answer based on rain probability, humidity, wind, and air quality, so you don't have to guess.
Mid-morning to early afternoon on a mild, dry day is generally ideal. You want the car to dry fully before evening, but you want to avoid intense midday summer sun, which dries soap too fast and leaves water spots. Temperatures roughly between 60–80°F (15–27°C) with low rain chance are the sweet spot.
That's exactly the problem SparkDry is built to solve. Rather than washing and hoping, you get a forecast-based score that factors in upcoming rain probability and precipitation amount, so you can pick a day where your wash will actually last.
SparkDry looks at your local weather forecast — rain probability, precipitation, humidity, and wind — plus air quality factors like pollen and dust. It combines these into a single daily score and a plain WASH, WAIT, or borderline recommendation, with a short reason so you understand why.
