Tempestas is a mobile first weather site. >95% of the development was done using chrome devtools to simulate a mobile device, and I also used a actual phone to validate that everything worked well. It It works on desktop, but it's primarily for mobile users. It's design was inspired by apple weather. It has hourly and daily forecasts, as well as a summary of the next 10 hours.

If you can, try this on your phone, it works better! If you can't you can use dev tools to simulate one!

Clone this, run npm install, npm run dev, go to http://localhost:3000, you know the drill, it's a next.js app.

You can optionally populate the .env file as follows if you want the AI powered summary (if you don't just leave it blank). You can use any OpenAI compliant provider, but the hosted version uses Hack Club AI, a free AI provider.
