are white helmets significantly cooler than yellow ones in hot weather?

No.

Helmet color has very little to do with how hot the helmet is while wearing it.
20 seconds of wind blowing over it while riding will equalize the surface temperature and then it is up to the air flow to the head to keep you cool.
When testing out this theory I found after an hour in the Georgia sun my BLACK 3/4 helmet had the coolest liner temp and my white full-face was the hottest. I also found that on the outside of the helmet the sunny side of the helmet can be scalding and the shaded side quite cool but didn't effect the inner liner temps side to side. The foam in helmets is a superb insulator and the color of the helmet has little to do with the helmet being hot or cold.
So as Duster said No.

THANX GUYS! I just ordered the yellow Nolan n104.

Think the yellow one will help your cool while riding as you will feel less heat of some drivers trying to run you down because they could not see you. Now with yellow they can see you better LOL. Enjoy the ride.

ON identical helmets the white will be cooler and absorb less heat from the the sun and if you are in traffic you MIGHT notice but given the other factors and how much heat your head kicks out I'd say it's a moot point.
Viz is good :thumbup:

I have two Gmax Modular helmets. One is a 44 and the other is the 54. My silver 44 is a LOT cooler on the 100 summer days than my red 54 - even though the 54 has better venting. I wouldn't even want to imagine how bad my egg would cook in a black one.
It's possible, but I really don't think it's just my imagination.

actually, white is supposed to be more visible than yellow per a study but I don't buy that.

:lol: ........Surely which color is "cooler" is just a question of personal taste? :lol:

Me, i tend to think any Hi-Viz (and that includes white) colors are "cool", because they might represent the difference between bing in an accident, and not being in an accident.

+1 .

Scientific response:

The main conclusion is that all the shades of yellow or yellow-green I tested worked well for any type of color blindness. The advantage of the fluorescent yellow-green jacket seems to be diminished a bit for color-blind people, but it is still on par with other types of yellow cycling gear. Anecdotal reports from a (very) few color-blind cyclists I've heard tend to confirm that fluorescent yellow-green jackets are good.

Me white Shoei Neotec much cooler in hot weather than my black Shoei RF1000 or red HJC.

When weather below 70°F no difference.
