Weather patterns in Oahu?

I am planning an outdoor wedding ceremony and reception in Oahu toward the end of February. Since everything will be outside, I am very worried about the chances of rain and heavy wind. Can someone tell me if there will be a difference between the North Shore and the West Shore when it comes to rain and wind? There is a location I like a lot on the Northshore but I would hate for the rain to ruin our wedding day. Any advice you could give would be greatly appreciated.

You can take a look at the following rainfall map for some info:

The west shore or waikiki area is a safer bet. Either way I would recommend a contingency plan - one where you'll still be happy no matter what the weather turns out to be for that day.

We have had outstanding weather on both of our February trips ... both North and West Shores. Honolulu/West -- that's the dry side of the island. North Shore - stands to reason that it may be rainier.

February is the rainy season. As much as I prefer the Northshore, I would plan an outside event on the South or West shores.

Actually, there wont be too much of a difference. The rain in Jan-Mar are kona storms that crop up from the south and sock the entire island, for days at a time, even an entire week. The west side of Oahu gets something like 75% of its rainfall totals just from these months alone, so there's little to no relief; you are equally at risk no matter where you are. The fact it may rain 5" per day in one spot vs 2" in another on the same day means nothing when it comes to your situation.

The west side's lack of rain is most apparent during the rest of the year, when trade wind showers can cause heavy rainfall in the windward areas that also move into the central plateau, while west Oahu remains sunny. Vog in the past year is also very bad on the southern portions of Oahu when the southerly winds blow; it will look like a bad day in LA.

Therefore, if you are planning to avoid rain, Feb is not the month for you -- you are chancing it all the way. Rainfalls are predicted to be higher than average for 2009 too.

Orangekitty -

While you are correct that during a Kona storm the whole island is impacted, you are incorrect that the weather is the same on all sides of the island.

I live right on the border between rainy and not as rainy. We often will chase the sun to the other side of the island when our side is hit. The south and west sides are desert, the north and east sides are not.

Hi Everyone! And thanks for your replies. I also contacted the Hawaii Department of Meteorology and here was thier response:

Aloha!

Congratulations on your engagement! While I cannot guarantee that it will not rain on your wedding day, I was able to pull up some archived data for the latter part of February for the past 10 years. February is part of the "rainy" season in Hawai'i, but most of the rain showers are light and short-lived. Rainfall for both locations was less than 0.5 inches on any given day, and winds averaged around 3-4 mph roughly from the east during the afternoons. From personal experience, there is a higher chance of it being overcast in Haleiwa while Ko'Olina is more likely to be sunny and a few degrees warmer, if you wish to take that into consideration as well.

If you have any further questions, feel free to contact us again.
