My boyfriend and I are spending a week in Maui at the end of October through beginning of November. I was wondering what the general weather and water temperature is like. I tend to get cold easily and didn't know how many warmer clothes I should bring. I am already planning on bringing a light jacket for night walks on the beach. :)
Maui Weather Is Very Localized
Weather on Maui is very localized, so the average temperature doesn't really tell the whole story. Also, the rain tends to fall all at once like a flash food, so the quantity of rain isn't that relevant except for the windward shore (i.e. Hana) where it rains all the time.
Key Aspects Determining the Weather You Will Experience on Maui
In my experience here's what you need to know about weather for Maui:
Your Strategy Will Determine Your Odds of Experiencing Good Weather
Assuming you're not staying in Hana, you've got two basic strategies that will determine the weather that you experience.
Strategy 1: You rent a car and drive to wherever the weather is good every day.
Likely Outcome: You'll enjoy a hot beach every day -- you just won't know which one until the day of.
Worst Case: You'll have one or two days of bad weather.
Strategy 2: You stay in one place all day every day.
Likely outcome: You'll have a few good and a few bad weather days.
Worst Case: The weather is miserable for your entire stay.
Even for those who are cold most of the time, and even when it's raining, it is rare that long sleeves are required. (The one exception is at elevation on Haleakala -- temperatures decline all the way to freezing as you reach the top the crater.) My wife and I have been on several multi week trips to maui at all times of the year and have never needed more long pants than those worn on the plane.
We normally wear short sleeves and swim gear (i.e. bikini or board shorts) Then we use cotton hoodies and hats or tuques to regulate body temperature up, or go shirtless and into the water to regulate down.
Maui is pretty close to the equator which has two effects:
In other words, Hawaii has an extreme peak of UV exposure in the middle of the day. That peak is difficult to manage even with sunscreen, hats, and sleeves; particularly if you are hard-starting a tan. This is demonstrated by the many tourists you'll see with sunburns on the top side of their bodies.
If you stay in the shade between 11a and 2p you'll have a much lower likelihood of burning.
The ocean water often feels cold when you get in, this is because your skin temperature is typically high in Maui, so you feel cold for a moment when you first get in. Once you are in the water, it is warm enough to stay indefinitely unless you are completely sedentary.
Many swimming pools in Maui are not heated and seem to be noticeably colder than the ocean. I usually can't stay in these unheated pools indefinitely because they are too cold.
According to this website
The temperature in Maui on October is usually around 31 Celcius - 21 Celcius. It tends to be colder ( by 1 degree ) in November.
