How many perfect days does your city get?
Decide what perfect weather means to you. We count every day that fits in five years of daily weather-station records (2021–2025) and put your city next to Medellín, the City of Eternal Spring.

About the Perfect Weather Check
Why is Medellín called the City of Eternal Spring?
Medellín sits about 1,500 meters (4,900 feet) up in the Aburrá Valley, roughly six degrees north of the equator. Near the equator there’s almost no seasonal swing, and the altitude takes the edge off tropical heat, so afternoons are warm and nights are mild in every month of the year. On the Eternal Spring settings (highs of 60–87°F, nights at or above 50°F), it averaged – days a year.
Does Medellín win on every definition of perfect?
No, and this tool shows you where it doesn’t. Medellín’s strength is temperature: it’s rarely hot and almost never cold. It’s also a green valley with real rainy seasons and plenty of humid, cloudy afternoons, so settings that demand dry, sunny days score it lower: it averaged – days a year on Sunny & mild and – on No sticky days. The “What knocks days out” panel shows exactly why.
Is there a Colombian city for every kind of weather?
Pretty much, because in Colombia you pick your weather by picking your altitude. Across 2021–2025, the top Colombian city for Eternal Spring was –, for Beach days –, and for Sweater weather –. Tap any preset’s winner in the Colombia panel above to compare it with your city.
Where does the data come from?
Daily highs, lows and dew points come from the nearest reliable weather station to each city, using NOAA’s Global Summary of the Day records. Cloud cover and rainfall come from NASA’s POWER project, which combines satellite observations with weather models. We use every day from 2021–2025 for 480+ cities: about 890,000 city-days in all.
Why might my number differ from other weather maps?
Different data and different definitions. Many maps use county-wide estimates or long-term averages. We count actual days at the weather station closest to each city, using the day’s average dew point. Our cloud cover is a satellite-based daily average over an area roughly 100 km wide, so it’s best for comparing cities, not exact neighborhoods.
Can I share my result?
Yes. The link always carries your city and settings, so whoever opens it sees exactly what you saw. “Download image” saves a ready-to-post card with both numbers, the month-by-month strips and each city’s longest streak.
Real days, counted one by one
Temperature and dew point
Daily high, low and average dew point from the nearest weather station with solid records, usually the airport, via NOAA’s Global Summary of the Day. Each city card names its station and distance.
Clouds and rain
Daily cloud cover and rainfall from NASA POWER (NASA Langley Research Center), which blends satellite data and models on a grid. A “rainy day” is 0.1 in (2.5 mm) or more.
The count
Every day from 2021–2025 is checked against all your settings at once. Missing days are skipped, and the result is scaled to a 365-day year, so a patchy station doesn’t look worse than it is.
Weather’s only one part of the move.
