  1. There is a ongoing discussion I am having with a runner friend of mine.
    Living in the midwest we have the pleasure of both high tempatures AND high
    humidity. So whereas in other locales, running in the morning is a good way
    to avoid a heat wave, here the low morning temps are accompanied with much
    higher humidity. So the trade off is to either run in the morning when the
    tempature is in the 70's but the humidity exceeds 90% or run in the evenings
    when the tempature is still in the 90s but the humidity is only around 50%.
    I say to hell with the 90 degree tempatures, the humidity is the killer.
    How do other runners in very humid climates deal with this dilemna. BTW I
    do not consider the northeast to be a humid climate. I grew up in NY and
    always though the humidity was very bad. That was until I moved to St.
    Louis. Holy [censored]!! I was quite shocked. People were walking around like
    this humidity was no big deal and I was thinking this weather has to be one
    of the signs of the apocolypse.

    Whoever invented that "feels like" formula for the weather channell
    obviously never exercised in a humid climate.

    The feels like formula is an estimate and better than the older formulae.

    That said, I would consider looking at the feels like number and choosing
    the lesser number. In the AM, the cooler temps and usually slightly higher
    humidity are far easier on me than the reverse.

    You should be able to calculate the heat index somewhere on the web but
    finding a prediction of the humidity might be a challenge.

  5. ok, i'll bite. whining manhattan baby checking in. well let's go over
    to weather.com and see what we whiners in the big apple can look
    forward to today...

    AFTER AN UNCOMFORTABLE NIGHT WITH HIGH HUMIDITY AND TEMPERATURES NO
    LOWER THAN THE UPPER 70S...TEMPERATURES THIS AFTERNOON WILL REACH THE
    90 TO 95 RANGE. THE COMBINATION OF HEAT AND HUMIDITY WILL YIELD
    AFTERNOON HEAT INDEX VALUES BETWEEN 100 AND 105 DEGREES...AND SO THE
    NATIONAL WEATHER SERVICE HAS ISSUED A HEAT ADVISORY FOR NEW YORK CITY.

    .....oh mr. ass, oops, i mean mr. mass....i suspect you got your panties
    in a bind because the NEW YORK YANKEES just thumped the Bosox over the
    weekend are are ALONE, ON TOP, and in FIRST PLACE in the American
    League East.

    hee hee hee....

  6. I know what you'd like to bite, but that aside... It's going to be 95
    here today, and with a heat index of 105, so it's hotter here by a full
    5' yesterday, and today.
    And to further my hypothesis that you are a completely uninformed
    moron, I am a yankees fan of 35 years.

  8. Actually, the killer is the dew point. Check out this link:

    http://veggie.org/run/humidity.shtml

    And yes, it has been in the 70-75 range for the last week here in the
    midwest due to the lingering moisture from hurricane Dennis. I haven't
    been able to complete an intended run for over a week.

    I've found that a good site for predicting how it will feel to run in
    the heat/humidity is at accuweather.com. They have what they call
    "RealFeel" temperature.

    For Saint Louis - http://tinyurl.com/8cexq

    RealFeel is a composite of temperature, wind, humidity, sunshine
    intensity, cloudiness, precipitation and elevation on the human body.
    So for example today in Georgia at 12 noon it is 88°F, zero wind,
    humidity 65%, sunny, elevation ~1,000 feet. That adds up to a RealFeel
    of 109°F. I see that Saint Lous has some pretty high temp/humidity/dew
    point readings as well. The best time of day looks like 3:00 AM. ;-)

  10. that is a thorough and good one phil. i generally use NOAA but i
    might switch....had the "RealFeel" for NYC today at 108F.

    i hope it doesn't cool down...huge Nike Race in Central Park tomorrow
    night...10,000 runners, most of which will not be climitized for
    this...ha ha ha....they'll be falling out by the hundreds...left and
    right.

    No kidding! Ever since 911 they've cried like babys. What wussies.

    All right, ya hooked me.

    [a] Face it, much of the northeast US - anything below the *real* New
    England meaning ME, NH, VT - is filled with whining pussies. If we
    NYers are the worst, you Massholes are right on our tails, so to speak.

    [b] What we *haven't* whined about to excess is 911. You're well aware
    of this, William: it's those xenophobic, homophobic, secularphobic,
    Khristian Konservative Klansmen in Wyoming, the Dakotas, Utah, Kansas,
    Nebraska, Idaho, Montana - the same [censored] who on 10 Sep 2001
    would've cheered on if not volunteered for an army of white christian
    men marching on the Sodom & Gomorrah of NYC and DC - who haven't let
    the 911 thing rest for a second.

    Yeah, suddenly all us Americans are in it together, they all deeply
    shared our suffering on that day and continue to, and let's kill all
    the Ay-rabs before they get their filthy hands on Kansas. I drove
    coast to coast last summer; it was amazing how much more fixated on 911
    they were 1000 miles from any meaningful civilization than anywhere
    near my workplace, two blocks from ground zero (my window looks a
    couple hundred feet down into the big pit).

    Also noted on that trip, amazing and sadly ironic: the entire mountain
    time zone appears to have a worse drug problem in crystal meth than
    NYC's seen in the post-crack years.

    P.S. Yankees suck, Steinbrenner doubly sucks.

    P.P.S. Anyone in a group I haven't just insulted: you probably suck
    too.

    P.P.S.S. No, I'm certainly not exempt. I suck.

  14. PB - You got to be kidding..... St. Louis is like the arctic when compared
    to the Quad-Cities. Ran in the QC area for 15 years and in lots of weather
    like 90s with 80-90% humidity. These towns are located in the Mississippi
    Valley and you can feel the pressure just pushing you down. As far as your
    question as to morning or evening with its different temps and humidity, I
    would think it would depend on how good your own body can sweat and
    evaporate..... Some runners overheat quicker than others.
    Since then I moved from that area three years ago to the southwest....
    todays temp was 95 but the humidity was 6%....... too bad I gotz a busted up
    foot.

    Similar here in western South Carolina. The humidity has been 100%
    every morning I have looked--the dew point is in the mid 70s. I spent
    10 days at 6800 feet in Montana and expected to be able to feel the
    difference of being back nearly to sea level, but instead I felt like
    the humidity made it hard to get air. Does the water vapor actually
    reduce the partial pressure of oxygen?

    I definitely find it feels cooler in the morning and try to do my
    running before 8. Bicycling I can do a little later as the breeze from
    moving faster helps.

    Yeah but it's hard to tell be exactly how much. Quoting from that
    page:

    * Saint Louis, MO on average is warmer than Moline, IL by 6°F.

    * Moline, IL on average is cooler than Saint Louis, MO by 8°F.

    If this were Star Trek, that web server would've shut down in utter
    self-conflicted confusion, allowing Kirk & crew to save the day.

    It's just comparing the average high and the average low.
    You can select the buttons for that and compare the two curves.

    Average high in St. Louis is about 6F more than the avg high in Moline, IL.
    Average low in Moline, IL about 8F lower than the avg low in St. Louis.

    If you think in terms of variables:

    avg_high_st_louis > avg_high_moline > avg_low_st_louis > avg_low_moline

    So, Phil's statement is correct:

    humidity are far easier on me than the reverse.

    You should be able to calculate the heat index somewhere on the web but
    finding a prediction of the humidity might be a challenge.

    Look for the nightly lows, which will be readily available. The
    dewpoint will be less than or equal to about that (about equal in humid areas,
    like bottoms of river valleys or downwind of oceans and large lakes).

    Dew point (Td) is the one that matters, not relative humidity (RH).
    90% RH tells you nothing useful. It says that for the air temperature,
    the water content (in grams per kilogram) is 90% of what it would be
    if the air were saturated. But cooler air saturates at much lower
    water contents. Saturation approximately doubles for every 10 C warming.
    90% RH at 50 F is wonderful running conditions, and 90% RH at
    95 F is horrible.

    Dew point tells you the much more useful figure (since nobody will
    tell you water vapor mixing ratio, which is the most useful) -- at
    what temperature would this water content represent saturation. A dew
    point of 86 F (30 C) represents twice the water of 20 C (68 F), and
    4 times the water of 10 C (50 F).

    Much of your cooling while running comes from evaporation -- from
    your skin, which provides saturation at ca. 37 C, 98 F. As the dew
    point approaches skin temperature, you lose the ability to cool by
    evaporation. I find that dew points over about 72 (22 C) are much
    worse to run in than those under. Air temperature itself matters much
    less than dew point (you won't find air temps of 50 with dew points
    of 72, so it isn't a completely independant sampling; still ...)
