The rain rule this uses
We look for a run of days in a destination's forecast that clears every check below. One failing day fails the whole run — a wet day is never averaged away against dry ones.
- Every day in the run: daytime high above 70 °F (21.1 °C) and no higher than 100 °F (37.8 °C), with a complete hour-by-hour forecast. A day with missing hours fails; we don't fill gaps with guesses.
- No thunderstorm hours, day or night.
- An hour counts as wet if the forecast codes rain, drizzle, showers or snow, or gives a 25% or higher chance of precipitation, or 0.2 mm or more of it. Wet hours between 23:00 and 07:00 count at 25% weight because you're asleep; storms never get that discount.
- No single day may carry more than 3 weighted wet hours.
- Across the whole run, weighted wet hours must stay under 5% of its hours.
- Runs are 3–14 days long, found within the next 16 days of forecast.
Those numbers are read from our live settings each time this page is rendered.
We do not gate on cloud. A warm, dry, overcast day is a good day; rain is what ruins a trip. Cloud only affects ranking.
Forecast data comes from Open-Meteo. The 0–10 score built on top of this is explained on the methodology page.
