The invention provides a tea making equipment water temperature control method and device, tea making equipment and a readable storage medium. The method includes the following steps: obtaining a target water temperature and an actual water temperature of to-be-brewed tea in the tea making equipment; determining whether a difference value between the target water temperature and the actual water temperature is within a preset range; and adjusting output power of the tea making equipment according to the difference value when the difference value is within the preset range. The method firstly obtains the difference value between the target water temperature and the actual water temperature. When the difference value is within the preset range, the actual water temperature is indicated to beclose to the target water temperature. The output power of the tea making equipment is adjusted according to the difference value so as to control a water temperature of the tea making equipment. Therefore, temperature overshoot when the tea making equipment is heated to near an appropriate temperature is avoided.
