Fastest Weather App in its Class

Fast downloads, fast loading and fast viewing.

Power Tools

Easy to Read Graphs

The graphs are designed so you can see the weeks weather in a glance.

You can easily see sun vs rain vs cloud.

Our unique Delta-Temperature graph allows you to easily see cold and warm fronts.


Compare Weather Simulations

You can compare multiple weather predictions, analyze the variance in forecasts, and decide on the likely outcomes.


This is not your typical weather app, but it's ridiculously useful if you're the kind of person that needs all the data. I use if for hitting weather windows when mountaineering and backcountry skiing. The newest feature that lets you compare all forecasts is fantastic. ---Kieran C.

Hurricane Tracks

These spaghetti lines are valuable for understanding the possible paths a storm or hurricane might take.

This is based on the GFS and GDPS models and the GEFS and CENS ensemble models. All together there can be up to 44 predicted tracks.


Sun and Moon

The sun and moon data is based on the SunCalc.net project.

Here we show sun and moon paths including the sunrise, sunset, moonrise, moonset, phase and angle.
