Return from holiday: how bad can the plot be? (end of August)

We have been away for a week on holiday. Although we have been active at the plot before going away, there has not been any general weeding for 26 days bar clearing a few beds to pop in autumn/winter crops. This can happen at this time of year as between all the rain showers we are busy picking crops. How bad can the weeds be? What crops are ready?
