In my country, the average temperature is 33 degrees, I keep them in a shaded area outside but they get direct sunlight at 9 am, there is no other better-shaded place in my house and we are not allowed to let them inside and I don't have a fan, so I made an area with my leftover cage grid and connect it to the connector then I and put a fleece on top and I gave them cold vegetables, but I feel for especially baby guinea pigs that they are too hot and they have a possibility to die from heatstroke or the temperature change.
