Made for real plans

Less checking.
More knowing.

Bellweather turns scattered environmental data into a forecast you can actually use.

Weather

The forecast, without the noise.

Current conditions, the next few hours, and the week ahead—organized around what matters now.

Water

Tides and rivers, close at hand.

Follow nearby coastal stations and stream gauges for the water conditions around you.

Air

See what you’re breathing.

Air-quality and smoke context help you decide when to head out and when to wait.

Sky

Look up at the right moment.

Sunrise, sunset, moon phase, and satellite passes give the sky a place in your daily forecast.

Grounded in observations

Useful data.
Made human.

Bellweather combines trusted public observations with a clean interface—so the source stays rigorous while the experience stays simple.
