I’m fortunate enough to spend 2-3 months a year in Hawaii and usually just grab a rental car when I feel like a drive. Oahu is a particularly easy place to drive, however, the H1 is an awfully busy road (one of the busiest in the US) so avoid that at peak times if possible.
Every time I head to La’ie it is windy and cloudy. Other areas of the island have the mountains close to the ocean, however, it must be the location of the area to the prevailing weather conditions that makes it this way. Of course it’s Hawaii so it’s still nice and warm!
If you know me then you also know I like a good sunset at Sunset Beach on the North Shore. A great place to watch the sun set over the water and then head home. Tourists and locals will be sitting on the beach with you each night.
