Pretty sure this as been asked before, but how do people manage with the various windspeeds, I think i have sussed out head & tail winds but I am flummoxed when it comes to working out other types of wind speed, would very much appreciate the help on this subject, many thanks.

I used to click for wind, but I just go by "feel" now.
Meaning I pretty much guess/eyeball it.
Headwind over 15 I double. Less than that, it's speed and a half.
Tailwind isn't full effect on short irons/wedges.
Maybe 3/4 or less.
Crosswind I play the yardage I figured.
Diagonal wind is tricky.
12 wind from 1 plays different than from 2.
12 straight and I'd do 14-18 added depending on club.
1 o'clock with 12 and I'm doing 9-13.
2 o'clock with 12 and I'm doing 6-10.
However, that's probably why I'm a middling PGA hack.
Use as a baseline to get it dialed in with how you see fit.
Others are better with wind than me.
I come pretty close quite a bit.

Using cosine, approximations are:
- 15 degrees = .25
- 30 degrees = .5
- 45 degrees = .7
- 60 degrees = .86
- 75 degrees = .96
So a 10mph headwind with a 4:30 clock position (45 degree) would be 10mph*.7 = 7y. If using Master Clubs, with say a 9i-3i, you'd then multiply 7y*1.5 = +10.5y, OR just add +1y to the original wind. A GW would be 7y*1.3 (tail would be .8), while a LW, would be 7y*1 (tail .7). Forty Five degree angles work the same for side wind, well, at least the initial formula. Side winds obviously have a different ratio than headwinds; Lw are around .7 (10mph*.7 = 7y *.7 = 5y adjusted aim), Sw .8, Gw and Pw .9, and 9i - 3i 1x, and 2i/1i, oddly enough, around 1.2x. A 10mph tailwind with an 8:00 clock position (30 degree) would be 10mph*.5 = 5y, before you add the necessary tail/side wind multipliers. That same 10mph tailwind, when accounting for side wind would be a 60 degree, or 10mph*.86 = 8.6y, then add multipliers. Cosine will always remain the same, but Pro and Beginner sets will have drastically different modifiers.
