Want to learn how to surf, need advice (LBI)

LBI: Long Beach Island.
So I've been wanting to surf for the longest time, but, I'm worried about my weight. I weigh at 147 pounds and have a height of 5.7. I've been dieting for the past month, have been practicing pop-ups in my room and been swimming actively since I was six-years-old. I have also been in the ocean too many times to count.
Locally I live not to far from Cocoa Beach, but I'm up here visiting a relative. Soon I'm going to get lessons, either next week or the week after.
To get straight to the point:
Will my weight effect me much? I know that actually practicing out in the water will help a ton, but should I be alright on a surfboard learning?
