Summers (June–August) are intensely hot and dry, with average highs of 38–41°C and frequent peaks above 43°C. Nights remain warm, rarely dropping below 25°C.

Sunshine is nearly constant, with up to 13 hours of sun per day and UV indices at their highest.
Winters (December–February) are mild and dry, with average highs of 13–16°C and lows near 4°C. Frost is possible but rare, and snow is extremely uncommon – falling only about once every five years and rarely accumulating. Days are sunny, with 8–9 hours of sunshine and minimal rainfall.
