Moving to North Shore, how bad is it having no AC with a dog?

Hi, we’re moving to Hawaii and are aware no AC is very common especially on north shore, however we have an Australian shepherd dog and are wondering how that would be or if it’s pretty tolerable. We’re coming in October and signed a 3 month lease but I just want to know someone else’s experience and if it’s best to find a place with AC? We just don’t want our dog to be too uncomfortable.
