Weather is the state of atmospheric change in wind, temperature, cloudiness, moisture and pressure. Weather lasts the entire day and may persist to the next day. It extends across the entire map, regardless of where the player is. Sunny days will be sunny everywhere and snow will fall on the Eufaula Desert as with everywhere else.

The weather in Portia is typically sunny, and can be sunny in any season. Sunlight is brightest and skies are clearest on sunny days, showing bright blue skies and thin white clouds in the distance during the day, sunsets that fade from yellow-orange to pinkish-red, and dark blue nights where the stars and moon can be seen.

Weather interaction

Weather forecast icon

Ack can forecast the weather for the next day after the player has hired him as a helper and upgraded him with the Meteorological Data Chip. Once these prerequisites are filled, the player can interact with Ack to bring up the weather forecast option.

When Ack predicts the weather, Ack's dialogue lines are as follows:

  • Sunny Sunny: I'm in a good mood today. Tomorrow will bring clear skies, as clear as my mood!
  • Cloudy Cloudy: Tomorrow is going to be cloudy. We won't be seeing the sun.
  • Overcast Overcast:
  • Rain Raining: It'll rain, rain, rain tomorrow. My arms will hurt and my cooking will be affected. How dreadful!
  • Snow Snowing:
