Bees need carbohydrate throughout the year. If you take any stores off you must ensure there is still enough food left for them, at least until your next look in. The flow does not just suddenly stop, it slows down and then they might move onto other sources or you might even have to feed . Your first season, so the bees have probably not produced vast amounts, but you will want some of your first ever honey. . I do not extract until mid to late August, depending on weather. As soon asc rop comes off I start varroa treatment, which is more important to me than the amount of honey I get.
Before taking any you need to check it is ready - is water content low enough - the shake test or refractometer. I put the bees needs ahead of my own.
Sorry I have not given a direct answer but there is not one
