Month by month

Share of days in each month that fit your settings. Darker means more of them. Faded months are outside the season you picked.

What knocks days out

Share of days that miss each setting. A day can miss more than one, so these don’t add up to 100.

Questions

Questions about the Weather Check

What counts as a no-AC, no-heater day?

A day with a high between 60°F and 85°F and a night that stayed at or above 55°F. Warm enough that you wouldn’t switch on the heat, mild enough that you wouldn’t need air conditioning. Move the sliders if your thermostat runs warmer or cooler.

How does Medellín compare with Cuenca, Mérida or Portugal?

On the No AC, no heater settings, across –, Medellín averaged – days a year, Cuenca –, Mérida – and Lisbon –. Pick any of them in the “Compared with” box for the month-by-month picture.

Does Medellín really not need heating or air conditioning?

Most homes here have neither, and the count above shows why. For the cost side, see No heating, no air conditioning: the line item Medellín deletes.

Where does the data come from?

Daily highs, lows and dew points come from NOAA’s Global Summary of the Day station records. Cloud cover and rainfall come from NASA’s POWER project. We count every day from – for – cities.

Can I share my result?

Yes. “Copy link” keeps your city and settings, and “Download image” saves a picture you can send to family.

How it works

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 result 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 the full season, so a patchy station doesn’t look worse than it is.
