Max dewpoint here last summer was 77 F/25 C.

The humidity before Irene was memorably high.

Right now it's 79F with a dew point of 69 (26C and 20.5C, respectively). I just stepped outside and I don't find it too uncomfortable. I would be miserable if I were to exercise and ride my bike or something. But if I'm just sitting in the shade, I can tolerate it just fine. It's not the most comfortable feeling, but I'm so used to it that it's quite tolerable. Now if it were 90 with the same dew point, it'd be a different story. So temperature matters more than just relative humidity.

I find more moving around dew point matters a lot more. Sitting still, the effect of high humidity is much less obvious. The sun also makes it worse.

Whoa. Dew point is 70°F. Thought it felt different. Just rose suddenly in the last few hours. Was walking around at about 9 am and it was still close to 60°F and felt normal.

Nowhere I keep thinking of beaches and swimming somewhere. Feels like I'm at the beach, without being at a beach.

I don't have much experience with extremely high dewpoints as when we get heat waves here in summer, it's a DRY heat (Temps over 100 but dewpoints are in the 30s). I have experience moderate humidity both in Hawaii and also on rare occasions here when we get temps in the low 80s with some subtropical moisture. So I don't know what extreme hot and humid feels like.

So my question is; which is more dangerous? a) A temperature of 98 with a dewpoint of 90 or b) A temperature of 140 with a dewpoint of 50. I know both are deadly if out for long periods of time but which would feel uncomfortable enough to send a person running inside for AC faster?

You're situation is too extreme to say anything over which is more tolerable. One benefit of dry heat, though, is along as you can keep sweating your body can survive. It's harder for your body to cool at higher dew points.

Which is one of the reasons I don't care that much for the extreme climates brought up / made up often. When a climate is too extreme, it's outside our personal experience and a different animal from our usual heat/cold that one deals with everyday. For example, I can bundle up for 20°F weather, but -30°F might have frostbit issues if I'm not careful with exposed skin that I wouldn't have to worry about for 20°F. Once a climate gets too far off to extremes, I just put it on ignore.

It'd be interesting to check what the highest dew points are in northern California. I suspect a 70°F dew point is far more unlikely than summer rain, especially June rain.

If you haven't experienced high humidity before, the easiest way to recreate it might be in the shower. Take a hot shower, make sure all doors and windows are closed. If it is fogged up inside the dew point is whatever the temperature is. If you live in a place without A/C and it's humid, say dew point of 72°F inside, whatever dew point your bathroom will be post-shower will be high. I recommend a cool shower temperature or you will sweat immediately after the shower.

Thats the thing with me. If you ever see me sitting still outside take a picture cause its a rare sighting. I like staying active hence why I grown to hate this weather, I hate sitting still and leaving shades down in the house.

Dewpoint 68°F here. Might as well go to 80 maybe the water in the air will cool me off. LOL!

Sitting home with the windows open and the fan on me. Felt nasty with the fan off, I tried. But otherwise, tolerable and I'm not sweating.
