The weather app for eating outside

Comfortable, calm, and dry underfoot.

Knowday reads the comfort, the breeze that lifts the napkins, and the rain window — then tells you whether today's good to set the table outside.

What matters for a picnic

The reads that decide a lunch outside.

Comfortable to sit out

Comfy

Not too hot, not too cool, not muggy — Knowday reads the feels-like and humidity for the sweet spot where lingering over lunch is actually pleasant.

Wind that lifts the plates

Calm

A steady breeze is fine; a gust sends the napkins and paper plates flying. Knowday tracks both the wind and the gusts, and calls a hard Skip when it's genuinely too blustery.

The rain window

Dry

It watches the chance of rain across your window, so you know whether you're packing up leisurely or sprinting for the car with the potato salad.

Shade and sun

UV 4

Enough sun to be nice, not so much you're squinting and burning — Knowday reads the UV so you know whether to grab the spot under the tree.

How it works

How Knowday thinks about picnics.

It scores the feels-like, humidity, wind and gusts, the rain window, and UV — tuned for sitting still and comfortable, not exertion.

Two honest limits: summer afternoons can spin up pop-up storms the model only partly sees, and it doesn't track bugs — warm, still, humid evenings tend to draw more of them.

Picnicking is one of fourteen plans Knowday reads — walks and rides, the lawn, the garden, camping, the night sky, and the water.
