But fans face frustration on the opening day of the tournament due to the weather conditions.
A statement released by Masters chiefs on Wednesday evening confirmed that they had already taken the decision to delay the time supporters can enter the course.
Car parking is also closed as fans will be forced to alter their plans if they have a ticket for Thursday's action.
The statement reads: "Due to forecasted weather on Thursday, we have decided to delay all gate openings in the morning.
"All Masters free parking will be closed until further notice while gate openings are delayed.
"Further updates will be shared no later than 5am (11am BST) via Masters.com and social channels."
Forecasts predicted bad weather for Thursday earlier this week, so the news doesn't come as a big surprise.
The worst of the rainfall at Augusta is expected in the morning and evening on Thursday.
A weather update reads: "A secondary stronger band of heavy rain and thunderstorms along a cold front is forecast from 6-11am (11am-4pm BST) Thursday.
"Occasional wind gusts of 40-45 mph are anticipated from 7-11am (12pm-4pm BST).
"A lull in precipitation should occur behind the cold front through 3pm (8pm BST) before scattered showers and isolated thunderstorms drift back into the region for the late afternoon and evening hours.
"Rainfall of 1.50-2.50 inches is forecast through Thursday evening."
