The Perseid rates started to riselast week! This chart will be a
fun way to see what worldwide observers are seeing in real time
hour by hour. http://www.imo.net/live/perseids2016/.
The best location is one devoid of any nearby light pollution, so
if you are observing at home find the spot against a shielding
wall without direct streetlights, motion sensor lights, etc. Mojo
and I will be in Lockwood Valley Thursday night till dawn Friday
morning, and at our annual "Stars Over Yosemite" star parties
Friday and Saturday nights. Free with entrance to the park,every
weekend excepting full moon thru Labor Day, a different astronomy
club's members hosts the weekend events.
Here are some tips and times. I cut out the pertinent few
sentences, but the writeup is very good and written by a personal
friend, Bob Lundsford who Mojo and I have worked with on NASA
Meteor Counting Campaigns since 1998! Excellent graphics, too! http://www.amsmeteors.org/2016/08/viewing-the-2016-perseids/

"Every year, the dust particles from the tail of the
Swift-Tuttle comet pass the Earth orbit and burn in our
atmosphere (about 70 miles / 110km above us) from mid-July to
the end of August.
When the dust and ice hits our atmosphere at around 37 miles /
second (59km/s) they disintegrate high up in the atmosphere
after making a brilliant flash of light. Most of these particles
are the size of sand grains, while a few are as big as peas.

Maximum activity is predicted to occur on the morning of
August 12th, when rates in excess of 1
per minute may be seen from dark sky sites. On the
morning of maximum the waxing gibbous moon will set between
midnight and 0100 local daylight time as seen from mid-northern
latitudes. This will free up the prime observing hours from
interfering moonlight.
-
As the night progresses the Perseid activity will slowly rise as
the radiant gains altitude in the northeastern sky. Not until
after midnight will the Perseid radiant gain sufficient altitude
to produce pleasing results. Anytime from moonset to dawn will
be the best time to see the most activity. Perseid meteors will
appear in every portion of the sky. I would suggest facing
toward the direction with the flattest horizon, devoid of any
trees or hills that may block you view of the meteors. If all
directions are favorable, then face toward the darkest portion
of the sky, opposite any terrestrial lights that may interfere
with viewing.
-
The best Perseid rates will occur on a 5 night segment centered
on August 12th. So if August 12th is
cloudy you can still see good Perseid activity over the weekend.
Just be sure to wait until the moon is low or has set before
attempting to observe.

The best night for viewing the Perseids will the morning
of August 12th. This year predictions by
Mikhail Maslov and Esko Lyytinen predict that we will cross a
part of the stream which has shifted closer to the Earth’s orbit
by Jupiter. Therefore rates could be up to twice as high
compared to a normal Perseid display. Normal rates for this
shower are usually around 60 meteors per hour as seen from rural
observing sites. Therefore this year rates could exceed
100 per hour. Note that meteor activity is
notoriously bunched, meaning that there are periods in which you
will see no activity and other times when you will see several
within seconds of each other. The quoted rates are an average
over an hour’s time.
