📝Brief

This challenge is part of the Frontend Mentor 30-Day Hackathon with submissions closing on Monday, October 6th. Find hackathon details here. During the hackathon, this challenge is free+ (everyone gets free Figma access) and will revert to free after.

Your challenge is to build this weather app using the Open-Meteo API and make it look as close to the design as possible.

You can use any tools you like to help you complete the challenge. So, if you have something you'd like to practice, feel free to give it a try.

Your users should be able to:

Search for weather information by entering a location in the search bar
View current weather conditions, including temperature, weather icon, and location details
See additional weather metrics like "feels like" temperature, humidity percentage, wind speed, and precipitation amounts
Browse a 7-day weather forecast with daily high/low temperatures and weather icons
View an hourly forecast showing temperature changes throughout the day
Switch between different days of the week using the day selector in the hourly forecast section
Toggle between Imperial and Metric measurement units via the units dropdown
Switch between specific temperature units (Celsius and Fahrenheit) and measurement units for wind speed (km/h and mph) and precipitation (millimeters) via the units dropdown
View the optimal layout for the interface depending on their device's screen size
See hover and focus states for all interactive elements on the page

Download the project and go through the README.md file. This will provide further details about the project and help you get set up.

Challenge FAQs

How can I get help if I'm stuck on a challenge?
The best (and quickest) way to get help on a challenge is in our Discord server. There are thousands of other developers in there, so it's a great place to ask questions. We even have a dedicated "help" channel! If you haven't joined yet, you can get an invite to our Discord server here.
How do I submit my solution?
We'd recommend reading our complete guide to submitting solutions . If you get stuck and need help, please feel free to ask questions in our Discord server, and we'll help you submit your project.
Is there an official solution I can take a look at?
We don't provide "official" solutions for the challenges. This is because there is no single perfect way to complete a challenge. Instead, you're encouraged to review other people's code in the community. You can learn so much by seeing how other people have approached the same challenges and giving them feedback.
Do I get a code review when I post my solution?
Frontend Mentor is a collaborative learning community where everyone can give feedback to each other. If you'd like to receive feedback from the community, please be sure to post a question when you submit your solution. The more specific you can be, the better. Being clear with your questions means you're much more likely to receive valuable feedback from others.
Can I use libraries/frameworks on these projects?
Yes! Our challenges provide professional designs but there are no rules on what tools to use. So feel free to use anything you like to build your projects.
Can I use these projects in my portfolio?
Definitely! Please do feel free to use whatever you build in your portfolio. Helping developers add professional-looking projects to their portfolio was one of the reasons we created this platform!
How often are new challenges added?
We launch a new challenge every two weeks. We alternate between free and premium challenge launches, so we launch one free and one premium challenge each month.
What is the difference between the desktop-design, mobile-design, and desktop-preview images in my starter code?
The desktop-design and mobile-design images show you how the layout should look at large and small screen sizes. The desktop design is 1440px wide, and the mobile design is 375px. However, try building projects to look good on all screen sizes. The desktop-preview image is a preview image used in the README file. You don’t need to reference this while building the project.
Can I use these challenges within my own free or commercial content/tutorials/projects?
Please visit our License page to learn more about how our challenges can be used within your own content. If you're unsure about anything, please feel free to contact us at [email protected] and we'll be more than happy to answer your questions.
