rendezvous 0 #1 January 15, 2003 Just wanted to get a feel for what others find as too cold to jump. Whats the lowest you would go out in to jump on a otherwise bright and sunny day ( snow or no snow ) Quote Share this post Link to post Share on other sites
ladyskydiver 0 #2 January 15, 2003 To date, -18F at altitude is the worst I've jumped in. I have no desire to jump in colder weather, but if I haven't jumped in forever, I may jump in colder.Life is short! Break the rules! Forgive quickly! Kiss slowly! Love truly, Laugh uncontrollably. And never regret anything that made you smile. Quote Share this post Link to post Share on other sites
billvon 2,989 #3 January 15, 2003 >Whats the lowest you would go out in to jump on a otherwise bright >and sunny day ( snow or no snow ) Ground or exit temp? It would depend on a lot of things. I'd do a hop and pop on a ground-temp -20F day with proper equipment. -25F at exit isn't too bad, but I wouldn't want to jump at -34F again without special equipment; too many problems with fogging and pain.

JohanW 0 #5 January 15, 2003 I've jumped in ground temps of maybe -5 or -10°C (say -25°F). At altitude, -25°C (-30°F) I guess. Maybe a little colder. Doesn't really get colder than that 'round here. So far, I have never done a hop 'n pop instead of a full alti jump just because of the temperature. The plane is heated, freefall is too short to get really cold (the adrenaline helps too) (but could those wimps doing hop 'n pops please hurry out of the door so we can close it after them?)Johan. I am. I think. Quote Share this post Link to post Share on other sites
jlmiracle 7 #6 January 15, 2003 The coldest on the ground was 8 degrees. The only reason I jumped was to stay current. I did not want to put student gear on again - EVER. Now that I have more jumps, I go with 40-50 degrees on the ground. JudyBe kinder than necessary because everyone you meet is fighting some kind of battle.

jerry81 10 #7 January 15, 2003 I hope to set a new personal record this weekend. If we're lucky, it'll be above or just around 0°C (32°F) on the ground, so it should be around -20°C (-4°F) upstairs. If we get a replay of the last weekend, it'll be -10°C on the ground and -30 up in the air (14/-22°F). In any case, I don't really care, as long as I'm jumping Quote Share this post Link to post Share on other sites
fudd 0 #8 January 15, 2003 My hard deck is at 0°C ground temperature. I've heard that it doesn't neccesary get colder the higer you go. Because the cold air sinks to the ground, it can be warmer at 10 000' than at ground level. Can anybody confirm this? There are only 10 types of people in the world. Those who understand binary, and those who don't. Quote Share this post Link to post Share on other sites

It can, but that would be really, really unusual, and you probably wouldn't be jumping because the weather would be so funky. Quote Share this post Link to post Share on other sites
tigra 0 #10 January 16, 2003 Some of the guys at the dz (the ones who have been around a long time....) joke that the temperature on the ground has to be higher than their age! That actually has a certain logic! maura Quote Share this post Link to post Share on other sites
Dumpster 0 #11 January 16, 2003 Same here- -18 at altitude- I can't remember what the ground temp was, but it must have been around 30- 40 or so- maybe- As long as it kinda feels sorta on the slightly warm side, for January, I'll jump.

rickfri59 0 #12 January 16, 2003 My last jump in early November (in Maine) the temp. at exit, 13,500, was -27F. Had my hands balled up into fists the whole way. My helmet visor began frosting over and by pull time was completly frosted. Won't try this again.......... Quote Share this post Link to post Share on other sites

Jimbo 0 #14 January 16, 2003 The longer I stay in this sport the more of a wuss I become with regards to cold weather. I don't think I'll jump in weather much below 45F. - Jim"Like" - The modern day comma Good bye, my friends. You are missed. Quote Share this post Link to post Share on other sites
AndyMan 7 #15 January 16, 2003 The temperature at altitude seems to stabilize at 'Damn Cold' from roughly November through April in Illinois. I Think 'Damn cold' is somewhere between -30 and -40 degrees C. On that basis, once the cold weather rolls around I don't care so much about the ground temperatures. I dress for the temperatures at Altitude, and assume I'll spend the plane ride in the back of the otter with a poorly sealed door. I don't think there's MUCH difference between jumping in late november, and jumping in late January. The temperatures at altitude are roughly the same. What do I wear? T-shirt, covered by turtle neck, covered by wool sweater, covered by fleece sweater, covered by jumpsuit. On the bottom, underwear, fleece pants, jeans, jumpsuit. It makes me look kinda like the kid in 'A Christmas Story'. I don't find that it hinders my range, much. I can still get big, I can still get small. Neck covered, full-face helmet. Good, winter gloves. Either ski gloves, or lighter windproof thermal gloves picked up at a hiking store. I can't stand wearing latex gloves, they just trap the moisture which for me seems to make things worse. Landing in snow is fun. _Am__ You put the fun in "funnel" - craichead.

Iezyka 0 #16 January 16, 2003 In the winter, the altitude changes from being told in meter to being told in degrees Pilot: "Which altitudes?" JM: "A solo on -15, and a three-way on -25" At the dropzone I jump at in the winter, we usually say it should be -25 celcius or warmer at the altitude we jump from.

CWiggum 0 #18 January 16, 2003 That's way too cold! I don't think I will ever jump if it's less than 45 or 50F on the ground. although, some day I might get very desperate. someday real soon "I'll tear up this ticket, but I'm still gonna have to ask you for a bribe."

ERICCONNELLY 0 #21 January 16, 2003 Quoteon a otherwise bright and sunny day ( snow or no snow ) Hmmm... Call me an addict but this weekend I exited in heavy sleet @ 5K, the sleet turned to rain at about 3K. I would jump on a sunny day as long as the plane can get off the ground. Prolly wouldn't get a full load unless the temp was above 0degF. Quote Share this post Link to post Share on other sites
Vallerina 2 #22 January 16, 2003 When it gets less than 45 degrees or so on the ground, I don't enjoy the sport as much (I guess I'm not a hardcore skydiver?). I'm paying good money for these jumps, so I may as well spend my money when I enjoy it most. Maybe if the costs of jumps varied with temperature....There's a thin line between Saturday night and Sunday morning Quote Share this post Link to post Share on other sites
riggerrob 643 #23 January 16, 2003 The only way I will jump in minus 10 degrees Celcius weather (on the ground) is if I can hide behind a tandem student. Quote Share this post Link to post Share on other sites
SkymonkeyONE 4 #24 January 16, 2003 Quote The only way I will jump in minus 10 degrees Celcius weather (on the ground) is if I can hide behind a tandem student. That sounds callous, but I agree. I generally do tandems with my hands behind my back anyway, only maintaining heading with my feet (I jump a bootie suit for tandems). It's pretty easy to hide behind tandem passengers when you are only five foot seven. Still, at 39 years old, I am much more likely to let a younger, more eager instructor take students up when it's freezing cold outside.Chuckie Quote Share this post Link to post Share on other sites
JJohnson 0 #25 January 16, 2003 An iversion layer probably is pretty rare. I took a friend of mine for a Tandem in March here in Illinois a few years back. Temp on the ground was 30 ish. When we opened the door at 10.5K, even with the wind whippping around you could feel the warmth. Really cool. Never felt anything like it. About nil wind on the ground as well.
