Wind Chill & Heat Index chart Fahrenheit
« on: October 03, 2024, 11:15:55 AM »
Thought this was useful...
Out riding in warm weather today, 96f and it feels every bit of it... I break out the evaporative cooling vest after 90f...

Chart is interesting. Not what one would assume… looks like 75 is the equilibrium. 75* is near 75* regardless of the speed..🤔

I was out for a ride before 10am for about 12-14 miles from home and it was 93 and I was comfortable as it felt much cooler. After a late breakfast, a business call with my insurance broker to discuss my upcoming insurance policy renewals for bike, auto, and renters insurance I went relaxed for a while longer enjoying some sweet tea and a small splash at Chick-fil before going to fill up the bike at Costco, didn't feel up to another 15 mile ride to save another $0.16/gal for 4 gallons of gas, economically not a winning proposition...would have burning 1/2 gallon of fuel on the round trip for $2.839/gallon vs the $2.999/gallon I paid.  Normally the spread in prices between the Costco at Orange Grove vs the Tucson Marketplace is less than $0.10/gallon different. I stopped for some BBQ at Dickey's BBQ, a couple Western Brisket sandwiches and a pulled pork sandwich... The Western brisket sandwiches went in the refrigerator for a few meals the next couple days...
I had a coupon for a free Western Brisket sandwich, this why I bought more than one sandwich. They 2nd Western Brisket and the pulled pork sandwiches were on sale for several dollars off normal. The sandwiches went in a bag tucked under the cargo netting I strapped to the rack. The drinks went in a plastic bag and I tied them to the side tank/engine crash bars of the Vstrom. I had a refill of sweet tea from Chick-fil-A and large cup of ice and a 24 oz aluminum thermos of ice in a plastic bag tied and strapped to the other side engine/tank crab bar. The cups from Dickey's leaked a bit because they tilted a bit in the large plastic bag. I didn't put the side panniers on the bike for the ride and the cargo net wasn't going to stretch enough or be able to contain the cups standing upright...so this my saddlebag like tie on transport...
I should get a milk crate to put on the rear rack or have taken my soft helmet rear bag on the rear rack. I often use it to take a change of clothes and some straps and first aid supplies when I have the rear hard panniers on the bike.
Ride home I checked temp before I put food on bike and refreshed evaporative cooling vest with about 16-20 ozs of cold water and dumped a small cup of cold water in my helmet to make it more tolerable. Temperature was 100f at 12:15pm, 30-40 min later at home (12:50-12:55 ish) the temp had risen to 102-103f. 5 min after seeing the 102f the temp had risen to 103f...
It was a very hot ride...I'm not acclimated to the extreme temps, have stayed inside in the AC most of the summer and today's ride was 2nd time I have ridden in over well over a year because of some health stuff going on...
Chart one would extrapolate the temps to be between 111-117f...it felt every bit of that! (40-45 mph max speed and 100-105f temps) Going over the Tucson Mountains through a bit of Saguaro National Park West I felt areas of cooler hot air amongst the cactus and desert scrub. That totally went away the last few miles home into just like a sauna. The evaporative vest was dry to the touch but my Tshirt was damp in my back. I brought the food in with my helmet and gear and stripped off Hemet, gloves, evaporate vest, and jacket. Then retrieved a couple more things before securing the bike. I stripped down and put the dual split in my bedroom to 61f to get my body temp back down to normal hydrating while I cooled off.

This is an interesting chart, I've not seen it before! I didn't know that riding on hot days felt hotter: maybe I'm just used to it?

When my brother and I [foolishly?] decided to tour the SW USA together in August of 1977 on our bikes we made our own 'swamp coolers' with our leather jackets: we'd wet down our T-shirts we were wearing (I always use a Pocket Tee so I can carry a pencil...) and put on our jackets, then adjust the zipper for the temperature we wanted. Boy, those shirts were cold to put on at first! It usually lasted a whole tank of gas, too, so we were much happier than our poor engines by the time we got to Mesa: since we had the Vetter Lowers on the bikes, his CB500K1 got hot enough to boil the carbs and finally stalled at a traffic light downtown, about 1 block from a motel with a pool. So, we pushed his there (after I rode mine up) and bought a room so we could head for the pool: the dang pool was 2 degrees hotter (106 degrees said its floating thermometer!) than the air temp after we ate some supper.

The next day we got up at 4 AM and hit the interstate north to the Grand Canyon before the sun got up: enough of that stuff! :)

Just as long as one realizes the actual thermometer temperature never rises or falls with speed.
It’s the theoretical felt equivalency temperature of a warm blooded mammal experiencing adiabatic/evaporative cooling..
You Arizona and NewMexico residents should know all about asiabatic (swamp) coolers…

A swamp cooler does reduce the actual thermometer temperature.

Abosolutely, the older ones by 20*, newer ones a bit better…

And just to clarify. The first sentence made no reference that a swamp cooler couldn’t lower the dry bulb temperature..🙄 It reads the actual thermometer temperature never rises or falls with speed…you know about the wind chill chart..
Please keep up….😏

Be nice guys, our tongue in cheek or other nuisances you can provide in person are hard to capture in print/written communication...so be nice...never hurts and teasing or giving someone a hard time is best done in person on people you never met...

Was another hot day here, 107f this afternoon and yesterday was 106f. Going to be 107 for next few days until Wednesday when it falls to 102f

Dang, that’s hot..
It was 84* here for the high today..

Need a rain. Four large class 8 combines cutting soybeans near the interstate just about shut it down…
HP’s and dot had signage and flashing light to warn people . Heavy black to dark brown dust, worse than heavy fog…
Combine air filters indicators were busy every 3-4 hours..

107*, dang that’ll make you trade off about 970 btu’s of “latent heat” per 1lb of sweat (h2o) evaporated…
