Products that do what I built a weather site for the Eastern Caribbean does
I built a weather and hurricane tracking site for the Eastern Caribbean islands (https://dewedda.com). PHP, MySQL, Cloudflare, Visual Crossing API, Leaflet.js for maps. The interesting part wasn't the stack. It was realizing how much the interpretation layer matters when you're building for a specific region. Wind descriptions, "feels like" calculations, condition summaries, all tuned for temperate climates by default. I've been reworking them for the Eastern Caribbean audience.

The UK MET office recently redesigned their site, adding a lot of additional whitespace, scrolling, and animations. This significantly reduced its usability for me, and left me wanting an ‘at a glance’ weather site. I made https://brolly.sh, a minimalist, plain text weather forecasting site. You can use it to view weather from around the world, with: 7 day forecast; Previous day log (so you can confirm it definitely was cooler / hotter / wetter / drier yesterday!); Hourly rain, wind, temperature, conditions; Hourly UV, air quality and pollen, including pollen type…

For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript. Source code and additional information is available on GitHub: https://github.com/dnlzro/horizon [1] https://html.energy/html-day/2025/index.html

Hello HN, I live in northern part of USA where winters are snowy. Whenever I took long trips, I always wondered what the weather along the route is going to be. For those who live in northern USA, you know weather can change frequently, so when you're traveling matters a lot, not just the route. To solve this problem for myself, I built https://navimodo.com/. NaviModo calculates the route, and then checks weather along the route based on your start time, and displays weather along the route. Change start time, and the whole thing is recalculated. I am not expecting any…

I have added OpenZones to Flowx, my Android weather app[0]. OpenZones are regions covering disaster zones where all the pro data in the app is freely available. I have created an 1200km diameter OpenZone over Florida with Hurricane Dorian approaching. So if you add Florida to the app, you can view radar, NOAA's GFS, NAM and HRRR models, CMC GDPS and RDPS models, and the DWD (Germany) ICON model. There are also predicted hurricane tracks from the NOAA and CMC ensemble models which I find extremely valuable to predict the possible paths of Dorian. This YouTube video[1] shows an example of the…

I was walking around New York last month during some light rain and noticed about half the people had umbrellas open. When the rain picked up a few minutes later, that number jumped closer to 80%. It got me thinking it'd be cool to track this somehow, so I built a website! I am taking a sidewalk livestream, feeding it into a YOLO model for people tracking, then sending a frame of each detected person to Gemini 2.0 Flash, which returns structured JSON about each person's clothing and if they're holding an umbrella. I also had fun making the site look like a TV weather channel. I showed some…

Basically was getting annoyed jumping between 5 different sites during this winter storm season, so I built "StormWatch". It's a no-fuss, mobile-friendly webpage (dashboard) that shows all the stuff I was looking for, but in one simple UI. Features: - Real-time NWS alerts with safety tips - Snow/ice/precip accumulation forecasts (+wind) - Dynamic preparation checklists based on your alerts - Supply calculator for your household size - Regional weather news It's free, no login required, works on any device. Just enter your ZIP.…

This is a service I've built to provide equirectangular cloud maps of the whole Earth, updated every 3 hours, for free. It's based on infrared and visible light data from EUMETSAT, processed to enhance the clouds and try to reduce the impact of surface temperatures on the final image. I built it because it's surprisingly hard to find these kinds of images in a format that's useful to developers and hobbyists. I was building a 3D ISS tracker and wanted to include live clouds but couldn't find anything good, so I got sidetracked, and here we are.

This is a simple single page weather app I made that grabs data from NOAA for where I live. If you view the html source you can see it's pretty easy to configure it for wherever you live in the U.S. You just have to edit the links. Personally, I like using this more than any of the weather apps out there because it's fast and has the data I want and need, and no ads. It uses the latest version of Bootstrap and jQuery. https://ezofficetech.com/branson/

This was posted before but I'm quite pleased to share a major update for https://oikolab.com. We now have available seven decades of hourly weather data starting from 1950 for any location in the world, thanks to the recent publication of ERA5 reanalysis data from European Centre for Medium-Range Weather Forecasts (ECMWF). ERA5 is gap-free, gridded dataset generated using data assimilation method (https://en.wikipedia.org/wiki/Data_assimilation), similar to NWP models but with the benefit of hindsight. As far as we're aware of, we're the first weather data…

Hello! I'd like share about my sideproject https://gribstream.com It is an API to extract weather forecasting data from the National Blend of Models (NBM) https://vlab.noaa.gov/web/mdl/nbm and the Global Forecast System (GFS) https://www.ncei.noaa.gov/products/weather-climate-models/gl... . The data is freely available from AWS S3 in grib2 format which can be great but also really hard (and resource intensive) to work with, especially if you want to extract timeseries over long periods of time based on a few coordinates. Being able…

As Dark Sky's API will stop working soon I thought I'd suggest a possible replacement. It is well known that most weather APIs just download data from NOAA and "repackage" them to JSON format. This means you will get data only for the nearest grid point which might be a few kilometers away and at a different altitude than your actual location. Meteosource combines more models (GFS, ECMW, UKMO, GEM,...). It compares individual models' performance to historical data and uses machine learning to create a single output. This approach minimises inaccuracies of individual models and feeds a…

Hello HN, This is a website I worked on during the holidays to fill the void of the upcoming dark sky shutdown. For me, the precipitation timeline was a view I was heavily relying on for everyday activities and planning. I had not found any replacement from the various weather apps. When I found pirateweather.net as a backend API, it gave me the motivation to put the pieces together and get back the experience I enjoyed. I then added more functionalities that I think was missing from the website such as a weekly chart view. I've been using the website reliably over christmas holidays. Hope…

Hi HN, I built an OSINT tool called Weather2Geo that helps locate where a screenshot was taken based on the weather widget data visible (e.g. temp, condition, and local time in the taskbar). People often post these without realizing how specific those values can be in combination. It works by comparing the given weather condition, temperature, and time against current data from thousands of cities. It’s timezone-aware, supports fuzzy matching, and groups results geographically to reduce noise. It’s most effective on recent screenshots, ideally taken within the last hour—since weather and…
