Several ways you could do this:

1) The easiest is to locate Venus right around the time of sunset. Carefully note its position in the sky relative to foreground and/or distant objects. Now head out the following day about five or ten minutes earlier and concentrate on that particular part of the sky that you were looking at the day before. You should be able to pick up Venus appearing as a tiny white speck against the blue sky . . . even though the Sun is still above the horizon.

2) Wait until the crescent Moon passes through the same part of the sky. The Moon is a much easier object to see in the daytime because of its larger angular size. If you know where Venus is relative to the Moon, you should be able to locate it against the daytime sky. This month, Venus will appear closest to the Moon on July 14.

3) A somewhat more complicated method is find a star in the sky that has the same declination as Venus. Then, based on the difference in the hour angles/right ascension between the two objects, Venus can be readily located. Unless you’re into the technical aspects of astronomy I won’t get into an explanation as to how to do this . . . but I’ve used this method many times to find Venus during the middle of day through my telescope.

Of course try to do this on a day when the sky is clear with no clouds or haze around. And it would also do yourself well to use binoculars to scan around that part of the sky where you presume Venus is located; the best type to employ for this job are 7 x 35 binos with a wide angle (11-degree) field, but you can also use regular 7 x 35 or 7 x 50 binos as well.

Good Luck!
