Severe wind noise can clip/distort the entire bandwidth and is difficult and in some cases impossible to fix. If you can post a clip, you get a more accurate recommendation and what can be done.
Otherwise, light wind noise can be attenuated with an high-pass filter or equalizer (EQ). Apply a filter or EQ plug-into to the offending track or bus. If it is on a dialog track, the human voice has very little low frequency content below 100 Hz, so start there and apply a 10dB or more to attenuate frequencies below 125 Hz or so. If there is no dialog, you can likely increase the hi-pass frequency point .. experiment for what sounds best. Some EQs and filters have presets for wind noise and plosives.
iZ's RX or Steinberg's SpectaLayers Pro would be the the best option but none are considered 'low cost. AFAIK, non of the RX plugs are included with VP. SpectaLayers Pro is included with the Sound Forge Pro Suite.

I should have posted more information. I absolutely have no knowledge about sound, frequencies, equalizers, filters etc. It will take some time to get acquainted with all these terms and their functions. But for all these years, all I know is bass & treble. I did watch a few videos, but couldn't grasp much useful information out of them.

@Musicvid - I received iZotope RX 7 Audio Editor v7.01.315. I believe it would be the full version as the latest version on their website is 8.

@rraud - I was trying to figure out how to export the audio track as MP3 file but ultimately found it. I have attached the file, though it is not as audible as in VP 18, so you may have to increase the volume.

Yes, you Izotope is your best bet. Try the automatic features first. Broadband pink noise can be reduced, but not eliminated. Yours has lots of distortion from clipping.

I do not hear any significant low-frequency wind noise distortion (even in my sub woofer system). The ambient surf sound is prominent. The din type noise can be attenuated some with noise reduction tools. Even with the magic of RX Advanced or SectraLayers, the 'dialog' will never sound like a close proximity boom or body mics.

1. Go someplace where there is no wind

2. Record the audio

For field-recording:

1. Purchase and attach a Rycote Windjammer over mic.
2. Shield mic from wind with a 24" x 36" solid (flag), piece of Foamcore, or stiff cardboard.

Or:

1. Find $3,733USD.
2. Buy a Cedar DNS 2 hardware noise-suppressor.
3. And, do the above.

I will try the automatic feature to see what it does.

I believe you are right. I got confused with the wind noise and the ocean waves sound. There is a wind noise, but not as much as the ocean waves sound.

This is a very old video back in 2012 when I was on a holiday with my family in Goa. The video was recorded on the beach and hence all sorts of noises. I am just trying to learn how to get rid of these noises.

For field-recording:

1. Purchase and attach a Rycote Windjammer over mic.
2. Shield mic from wind with a 24" x 36" solid (flag), piece of Foamcore, or stiff cardboard.

Or:

1. Find $3,733USD.
2. Buy a Cedar DNS 2 hardware noise-suppressor.
3. And, do the above.

The video was recorded on my Sony DSC-HX10V mirrorless camera with no provisions to attach any accessories. I had purchased this camera just a few days before we went for the holiday.

Around 4 years ago, I purchased a DSLR camera which is having all the ports to attach external accessories. So I will definitely keep your suggestion in mind henceforth.

In iZotope, I tried the Repair Assistant button. After analysing, it presented me with four previews, an original and the rest A, B & C processing. I heard all the previews but couldn't figure out any much difference.

I would like to reduce the ocean waves noise to any extent possible.

Are there any specific steps I should try irrespective of any software?

@Alok-Sharma Audacity is free but good also, well worth a try. There are tons of tutorials on reducing noise using it. I found that not attempting to do it all in one go, but twice (converting to lossless first,) using not the highest settings produced good results. You would need to be able to find a section that has just the noise element that you want to remove, the longest piece you can find.

These are a few notes I kept …

Audacity noise removal

https://sophia.smith.edu/blog/smithvideo/noisereduction/

Works for regular noise, not irregular 

#1 Select 3 to 6 seconds with only ambient sound, no speech. 20 seconds is good.

Note that I found using a longer time was also beneficial jn-

#2 Select menu item effect, noise reduction 

#3 In dialog set noise reduction between 8 to 12.  Decides how much noise will be filtered out. Keep as low as possible.  Controls the amount of volume reduction to be applied to the noise. For light noise, adjust this parameter between 12 and 15dB to reduce the noise but maintain the integrity of the interview audio.

#4 Set Sensitivity to 1.  This control decides what will be filtered out, how aggressively. Keep as low as possible. controls how much of the audio will be considered as noise on a scale of 0 to 24. Set this control to a value that will effectively reduce noise without distorting the interview audio.

#5 Frequency Smoothing band.  Set to 3 or less.  Higher values will make audio less clear. 6 is recommended also. can reduce the perception of noise artifacts by spreading them out over one or more frequency bands. This parameter is best set to a value between 0 to 6

#6 Click the Noise Reduction button.

#7 Select Effect again.

#8 Click OK, this gets the noise reduction print.

#9 Select all

#10 Ctrl-R .. Repeat noise reduction.

@JN- Thank you for the detailed instructions. Even though those videos are just old memories, but for the sake of learning, I am anxious to know how basic audio editing is done. So once I know the basics, then everything would be fairly easy.

I believe I can do audio editing in VP 18, SFP 14 & RX 7, but there are so many options that I don't even know their meanings and the same with video also. So it will take some time to get acquainted with them.

I will try to replicate the instructions you mentioned & post an update, though it might take some time.

Hey, Alok, my last post (and possibly jet's) was more tongue-in-cheek than serious (though mine is a valid field-recording technique); having a bit of fun at your expense. But thanks for being a good sport and rolling with it!

Not at a problem :-)

Actually my bad, I should have posted all this information at the very 1st so that it would have been easy for the members to understand.

It's a Korean class, but please refer to the contents below.

I believe the best thing is to try to reduce wind noice as much as possible when recording. For my old Panasonic with inbuilt mic I used part of a sock wrapped around the front part of the camera to shield the mic as much as possible. I have found with nice very difficult to get rid of in post so that was my 'homebuilt' solution.

Thank you @lee-g - Since the video is in Korean language, hence a bit difficult to understand, but I can get somewhat by watching the steps.

Thank you @Werner_NOR - You are right, if things are done correct at 1st place itself, then it avoids all the hassles later.

Again, as a field-recording technique, I can't say enough about the Rycote Windjammers (and a flag or piece of board to block the wind). They're pretty affordable and they make them for just about any type of mic (even tiny built-in camcorder mics). They really do a good job in impossible situations. Also, that Cedar box is weirdly effective (yet, insanely expensive!). Doesn't work on everything, but for certain types of ambient noise it's like magic.

Here's the windscreen that came with the optional shotgun mic-capsule I ordered for my Zoom H6 recorder. Highly recommend the H6! Its backlit color screen makes recording in the dark a breeze. The interchangeable mic-capsules (they make several different ones) are what sold me on the H6. Miles ahead of my clunky, bulky Audio Technica AT835b shotgun-mic + portable MiniDisc recorder rig I used to use for field-recording. Use a simple manual clapstick for syncing to any video camera.
