I know you can't count on weather.com to be 100% accurate, but I have been watching the Kailua weather for July as we plan to spend the first two weeks there in July 2013. It looks like there have been so many cloudy days with 40-60% chance of rain each day. At the same time, Honolulu has been sunny with little or no rain.
While I'd rather be in Kailua with our family (6 adults and 2 babies), I don't want to have to be chasing the sun every day just to avoid gloomy weather. For those of you who have been in Kailua in July, are the weather reports I've been reading accurate and should I look to a different part of Oahu if I want July sunny days?
