Towering Q is correct: the mean MAX temperature is 26.5. Designing a system - particularly an off-grid system- for the peak of the peaks is folly, as we're collectively finding.
While the modal (most frequent) MAX summer temp would be a good thing to know, as a Rottnest regular I bet it's below 30C. And it's an island: usually plenty of breeze from late morning.
Always a great view from final of the turbine chugging away - gladdens my heart.
