There is also a trick that was reposted by Mauvecow to determine whether or not your shot will hook. Imagine the circular wind indicator being divided into degrees, i.e. 90 degrees is straight up, 45 degrees is up/against, 0 degrees is directly against, etc. Look at the wind strength, and then look at the following chart. If the wind pointer is below the 'wind direction angle' given on the chart, it will hook. If it's above that angle, it won't.
Wind Wind Angle (direction) 1 0 2 60 3 70 4 75 5 78.5 6 80 7 81.8 8 82.8 9 83.6 10 84.3 15 86.2 20 87 25 87.7 (Credit to Mauvecow, reposted by shotgunkelly. Found on gbgl-hq.) Also check out this visual guide my MezzanineX. You might find it's easier to process.
