Best to stay out of the sun (when it is most intense)
.You can buy head sweat bands, which are designed to work like a radiator, after being soaked in water.
Work great, especially if you carry ice water.
I was able to purchase hooded long sleeve surfer shirts (we call them rash guards)
at Costco (Hawaii). They were manufactured by a local - unfortunately the bag is sealed, and there is no
outside label to identify who made it.
NRS sells UV Buff head ware which can be worn twelve different ways to wick moisture away and keep you cool.
and it blocks 95% of the suns rays: neckerchief, headband, hairband, wristband, face mask, balaclava, hair scrunchie, saharine, pirate cap, beanie, bandanna, and helmet liner. Or invent your own style.
Even with all the protection, mentioned (sunblock, lip balm, SPF 50 sunscreen, hat with flap, you can still get fried if you are out too long in the sun,
and/or burnt by the wind.
In Hawaii, the sun is even more intense as it is closer to the equator. Protecting your lips with Lip balm is especially important, as you can be severely burnt without it.
The best protection is not to be in the sun (11AM to 2PM) PST, when it is most intense.
I prefer detecting after 4PM when most bathers have already headed home, and you don't have to worry
about staying too long as it will soon be dark. You have to be very disciplined and get off the beach
here before 10AM if you go the sunrise patrol route.
TH is right about the long sleeve surfer shirts, they are the most comfortable in and out of the water and afford you some protection. I put the SPF50 on first then the shirt. Don't forget the SPF lip balm. After my wife had a rare skin cancer we both get checked every year. The sun is not your friend, especially here in Florida. Never take the hat off. You may be tempted to when it gets hot, but try putting a small bag of ice under it, works for me.
Good luck Tupperware, thanks for the warning.
