A funny day today...

No hand launch for me but I was out doors all day long taking soil samples. The morning started out cloudy, cool at 40ish degrees and a wind of 10 to 12 or so. The cloud cover started to break up and the wind started to die down about 10:30. About noon or so the sky was totaly clear and no wind at all. The temp made it to 55. I was down to a long sleeve T-shirt and that was too hot. I expected to feel a thermal or two pass me by but never did. I then started to really look for thermal signs. I never saw a one! I thought the day would be prime for some serious activity. "Cool" air and "hot" sun soaking the dark colored earth should have produced something I thought I even saw a couple of hawks but they were flapping their wings pretty much the whole time I was near them. The didn't do that for long as they disappeared within about 10 minutes. Even they must have figured it was not good for flying

Not much of a story but a story none the less.

There is ALWAYS lift. The fact that you didn't feel it means you were not looking for the right signs for that day. I have knocked 3min after 3min flight in active snow. Next time throw a plane and figure out what the signs are for the day.

I don't know- I had a day yesterday that should have had great lift but had none that I could find. I watched buzzards and other soaring birds struggling to find a ride. I even had a buzzard or two wander over to where I was flying to see if I'd found anything.

When I see the birds having a hard time, I figure there's no way I'm going to get anything. I still fly anyway, but it's just launch practice under those conditions.

And yeah, I know there's always lift, but sometimes you have to be at several hundred feet to find it.

Because of global climate change every year I'm finding more thermals than the year before.

Again I strongly disagree. We have much better wing loading than birds and I have flown lift they have fallen out of. It may not get you specked but it can get a long flight. I dropped 8sec in 1,2,3,4 at the Bruce this year and never got above tree height. There is always lift.

Depends on what you're flying. You might have a Snipe, Stoebel, or something like that, right?

I fly smaller scratchbuilt DLGs, and trust me- they are much harder to thermal and fly than those high dollar contest birds. When I manage to speck my Icarus of Bug, it's a grand day and I feel like I've accomplished something.

Smaller span gliders are more difficult to maximize. However they still benefit from light lift and can stretch a flight when flown in light air. On difficult days look to get some outliers, 20% better than your average flight is good. Even if your average is 40 sec, a 1:00 shows you flew the air better. Change your definition of "lift" and you will have more fun and more success.

There is always lift!

Doesn't this imply that the day was a high-pressure one, with inversions preventing any thermals from lasting long before being stopped by hitting the warmer air layer above ? There probably were (as Austinhlg stated) thermals about, but they were probably small and short-lived.

Thermals can form in convection cells. You might have had the misfortune of flying in the region where the air was coming down softly. Fly farther out.

Yes its 3 miles that a way. Quite often there is NO lift in the area that is accessible to the DLG after launch.

There's lift, and then there's lift. I can usually find those ground bubbles that AustinHLG mentions about any time and float around in them 50' off the deck. It just seems that the lift that will take you to 400' is much harder to come by.

The days I really don't like are the ones where you find sink everywhere. Shorter than "dead-air" flights then. LOL
