NIT Srinagar Alumnus · CreatorI built pastweatherinfo because I was curious what the weather was like on days that mattered — birthdays, anniversaries, that one unforgettable trip. Historical weather is scattered across dense APIs and datasets, so I made a fast, free, and friendly place to rewind the sky for any date and any place on Earth.
What PastWeatherInfo does
Type any city, US ZIP code, or Indian PIN code, pick a date, and choose how far to look back. PastWeatherInfo shows the temperature, rain, and snow on that exact date across the past 5 to 50 years — with records, averages, and interactive graphs.
Everything runs in your browser on open data. No accounts, no tracking, no cost.
Why I built it
- ✦ Historical weather is genuinely useful — for travel planning, curiosity, and settling arguments about "was last summer hotter?"
- ✦ The raw data is powerful but intimidating. I wanted a clean interface that anyone can use in seconds.
- ✦ It's a fun engineering challenge: fast geocoding, reliable postal-code lookups, and hand-drawn SVG charts with zero libraries.
Built with open data
- ✦ Open-Meteo — historical & live weather (ERA5)
- ✦ OpenStreetMap — place search
- ✦ Zippopotam — US ZIP codes
- ✦ India Post API — Indian PIN codes
