What usually happens next
Call your doctor soon rather than waiting for a routine visit, and sooner if you have heavy thirst, frequent urination, weight loss you can't explain, or blurred vision.
A result this high is confirmed and acted on quickly, usually with a treatment plan rather than a wait-and-see.
When an A1C can read wrong
A1C counts sugar stuck to red blood cells over their roughly three-month life, so anything that changes how long those cells live can move it without your glucose changing: anaemia, iron deficiency, kidney disease, pregnancy, a recent blood transfusion, and some haemoglobin variants. If your A1C and your glucose readings don't agree, that's usually why, and a fasting glucose or fructosamine can settle it.

Questions
Is an A1C of 13.0% good?
13.0% is in the diabetes range (6.5% or higher). A second test confirms it, and your doctor reads it with your other results.
What average blood sugar is an A1C of 13.0%?
About 326 mg/dL (18.1 mmol/L). In the ADAG study, 95% of people with this A1C had an average between 240 to 347 mg/dL.
What is 13.0% in mmol/mol?
119 mmol/mol. Many countries print A1C in mmol/mol (the IFCC unit) rather than percent.
