Wind in Oahu is more important than any other weather factor. Too little of it and your nice new home in Kailua will feel like a steam beath. Too much of it and your hilltop home on Hawaii Lao Ridge could feel like a constant tornado.

The temperature in Hawaii only fluctuates about 25 degrees all year. In the summer it might get 90 degrees on the hottest day, and in the winter it might be 65 on the coldest day. Also, it doesn't fluctuate much between day and night either. On an average summer day it might be 75 at night and 85 in the day.

But the problem is not the temperature so much as the wind. Even on a real hot day of 90 degrees in Oahu, if the wind is blowing about 20mph, you won't feel hot at all. But if the wind is not blowing, it feels hot even if it's only 80 degrees. I can't really explain the science of it, but we all know it's true.

There are some great houses in the back of Hawaii Kai up along the hills, that get no wind. None. Especially back in Kamiloiki against the hillside, there just isn't any wind in there. By looking that geography you would never guess it, but it's true. There are even some houses in very windy Hahaione valley that don't get much breeze. The worst is probably the leeward side of Oahu, like Ewa and Kapolei. There are parts of those towns that are trapped behind something blocking our precious trade winds.

On the other hand...
I once visited a beautiful house on Mariner's Ridge in Hawaii Kai that had expansive ocean views. At about $1.1million, it seemed like a good deal. Then we opened the windows and the wind started howling at about 900mph. I had to hold on to my clothes to make sure they didn't get ripped off. I felt like we were reenacting the movie movie Twister! Wow, you could barely open anything up there without getting blown away.

About 90% of the year, the trade winds blow at least 10mph, cooling off our warm tropical island. But on those other 10% days, the wind either stops or becomes what we call, "Kona winds." A word of advice, if you have to shop for homes on a Kona winds day, make sure you go back and check the house on a tradewind day to see if it gets the trades.

A Kona wind day will deceive you, because they are not the prevailing wind and they are hot. Very hot. Sometimes, Kona winds just feel like no wind, but if you could measure you would see there is a little movement from the south. O yeah, trade winds come from the North East.

If you get nice trade winds in your home, it will make your home a much more pleasant place to live. It really doesn't matter where you buy your home you need to check for the wind. Whether you live in Mililani, Aiea, Diamond Head, or Kaneohe, you may find that a house right accross the street from yours gets a great breeze while yours gets none.

A lot of it based on the direction your home faces. Most homes have one or more sides with more windows than the other sides. You want most of your windows facing the trade winds, so they can get it. They only need a little window to get out.

So check your wind. It could be all the difference.
