Narrative:

30 minutes out we checked ATIS via ACARS and it showed the field to have strong gusty winds but nothing excessive. As we leveled off at 8000 ft approach informed us the field was now experiencing winds out of the west at 44 knots gusting to 58 knots. There was no alternate filed for us nor was there alternate fuel onboard the aircraft. It was at that point the captain [advised ATC] and asked for a diversion to a nearby field which was south of the weather system causing the problem. We began the divert with 7700 lbs and landed with 5500 lbs. We arrived without event.during the preflight the captain called and queried the dispatcher about the weather and asked if an alternate was required. They both agreed it was not required but when the question even arises I'd at least add some extra fuel next time.
