It is fine.  WBGT is a better source for what it actually feels like vs heat index.  Use that instead, it is what many outdoor public jobs, sports teams and the military use.  

Bro I don't need any instruments lol, I went outside for about an hour and it's already vile

Aruba dewpoints without the beaches or scenery or breeze.

IMO the mosquitoes have been a bigger problem than the ticks so far this year. As you mentioned they are about to be a bigger issue, not looking forward to that. 

What's crazy for me is how little mosquitoes have been an issue where I am. Usually they're harassing me when I water the plants but so far they've been kind of absent. 

[Sundog]

I personally don't look at the heat index, I just go by the dewpoint number. I already know exactly how every dewpoint temperature feels to me, so I know what to expect. 

I also take into account if it's cloudy, if it's really breezy, etc.

The heat index is fine for general purposes of how it actually feels out since it’s what the air temperature combined the dew point feels like. But the issue is that it’s based on the conditions in the shade. The WBGT takes into account what it feels like in the direct sunlight. So the threshold temperature for the WBGT action to reduce activities is much lower closer to 90° instead of the 100°+ for heat index. Winds and clouds are also taken into account with WBGT. So in reality it may be dangerous for certain outdoor activities at lower temperatures than what the heat index says in the sun on a clear day. So even if there isn’t an official heat advisory, the WBGT could recommend reduced outdoor activities.

All these years (20+) on weather forums and this is the first time I'm hearing about the WBGT.

Tick bite cases have spiked here in the northeast.

I pulled 5 dog ticks off my dog after being in the back yard only and found one on a jug of pool chemicals- just crazy for July!!!

The bottom line is that the heat stress on the body has been increasing no matter what index or scale you are using when the dew points and temperatures keep rising.

More clouds now

86 / 73 here

These dew points have been absolutely insane. Day after day it's 70+. Floridian humidity on a daily basis

80°+ dewpoints used to be rare.  Now its quite common to find them when perusing the maps or various station observations.

Changed my plans today for water park to big snow. It’s unbearable even for a water park. I was working on my veggie garden this morning and was drenched in sweat in 20 minutes.

I planeted a tomato plant and a jalapeño plant in a raised garden. It’s doing ok so far. Got them at Home Depot lol

85/77 right now, yet another day with 75+ dew points, this has to be a top 5 most humid summer at this point

Very impressive for the NW corner of NJ to be getting close to 80° dew points. Has been happening quite a bit in recent years. New all-time highs for FWN. Action Park was my favorite place to go during the summers back in the 1980s. The dew points were much more comfortable in Sussex County back in those days.

As if we didn't know...

Next week's heat pulse won't be as hot as the June shot we had perhaps...

July is just brutal around here these days---AC on non stop.    Sun angle still strong.  August usually gives us a bit of break

In urban areas I feel august is way worse. It's been baking for too long and all the concrete retains the heat. Plus the humidity is just as bad as July.

yeah I hear you-out here it's usually a bit better and the sun angle is lower...I remember a few days last year with temps in the mid to high 70's second half of the month

Our first “nip in the air” is usually early September where I live. But just to echo how ridiculous this humidity is day after day. We shouldn’t constantly be over 75 dewpoints.

Yep.   To think around here the homes were built in the 50's-70's with no central air b/c it was not needed.  Now it's a necessity.

Agreed.  We had our humid days, but never to this extent.  And there is definitely a big difference when the dewpoint is 70 vs. 78.  I always found 70ish tolerable.  I'm going to wager a guess that the actual amount of moisture in the air grows exponentially as the dewpoint value increases (as opposed to linear growth which wouldn't have as dramatic an effect).

that is why you should move to phoenix if there is no monsoon dewpoints are tolerable in the summer..
