The months from October to January are significantly wetter than those between February and September, Generally speaking Spring in Snowdonia is drier than summer with August being particularly wet. Warmer weather tends to be found nearer the coast. Hill fog is often encountered when hiking around Snowdonia and the summit of Snowdon is often shrouded in mist - so check forecasts before venturing out and be prepared, It can be extremely cold on the high ground with easterly winds in winter and snow and ice is a common feature inland from the coast.
