Lovely Weather We're Having is a goal-free explorer game. It uses local weather data to simulate the weather conditions where you are.

You're locked out of your house in an odd, peaceful landscape with your trusty pooch. Interact with a dozen NPC's whose moods change with the weather.
Jump off a roof. Kick a rock. Run through flowers. Be outside!

"The vibrantly colored world of Lovely Weather We're Having doesn't take you back to a specific time necessarily, but to a mind set, when the world seemed bigger and brighter and more mystifying."
-Jess Joho, Kill Screen

"Lovely Weather is a clever little mood stimulator on the contemplative end of the scale, a kind of dynamic Zen box. You open it and poke around a little and maybe close it, thinking “Is that all?”
And then you come back, and the weather’s different, and the time of day’s just so, and it takes your breath away."
-Matt Peckam, WIRED

"it looks gentle and colourful and weathery which is rather appealing as I’ve had a nice morning of typing and listening to the rain fall outside."
-Philippa Warr, Rock Paper Shotgun

"Watched the trailer and I have no idea what the game is about."
