Typically after the fruit sets, it should be 2-3 weeks to harvest. If it's cooler than usual in your area, then this could make it longer for the fruits to turn. Tomatoes need heat to ripen well and if they don't get that, they may stay green for some time, though too much heat isn't good. Over 85 F. and tomatoes slow down their ripening. Over 95 F. and ripening virtually stops. About the only thing you can do is wait. However, if you have to, you can always pick some and allow them to ripen in a windowsill indoors.
