Temperature. Temperatures at sea level generally range from highs of 84–88 °F (29–31 °C) during the summer months to 79–83 °F (26–28 °C) during the winter months. Rarely does the temperature rise from above 90 °F (32 °C) or drop below 60 °F (16 °C) at lower elevations. Temperatures are lower at higher altitudes.
What is the best thing to wear on a plane to Hawaii?
Wear loose-fitting clothing that cover your arms and legs, but can be rolled up. Clothing that includes natural fibers like cotton, feel most comfortable. I normally wear long trousers that can be rolled up and snapped into capri length. Andy sometimes wears hiking trousers with zip-off legs.
