The weather and temperatures vary every day on Howrse. You can view them on the top right of each game's page. You have to take them into account to find out where to put your horse to sleep for the night. When the temperature is below 10° C/ 50° F, it is recommended that your horse sleeps in his box at night to avoid damage to his morale. The seasons are also used to determine an equestrian center’s crops.

Seasons last one week on Howrse. Autumn starts on the first of each real month. As it lasts a week, winter therefore starts on the eighth day of the month, spring on the fifteenth day and summer on the twenty-first day. Summer lasts until the end of the real month in progress to be able to start the cycle of seasons again on the first of the following month.

The temperature is linked to the current season, but also the amount of grass in the pastures. Grass is in abundance in the fertile pastures in spring and in summer, but becomes sparser in winter.
