The Apennine mountains provide relief from Italy's north winds, turning the climate of the Liguria coast to the mild side. When the north winds do blow in Summer, they tend to clear the humidity from the air, and wanderers of the Cinque Terre will be treated to great views, sometimes all the way to Corsica. July and August provide the highest termperatures in the Cinque Terre.
The rainfall data below is from nearby Genoa, so it may be slightly different from Le Cinque Terre. Visitors to the Cinque Terre should expect frequent rains of short duration in the Spring and Fall. The dryness of the summer concentrates the flavor of the grapes that grow in the terraced hillsides that hikers traverse between the five villages.
Summers are hot and clogged with tourists. While there are frequent rain storms in spring and fall, the views and the relaxed nature of hiking make a better experience. That said, heavy rains can wipe out sections of trail. Day trippers should make sure they know the weather in advance. I've had perfect hiking weather in November, while the olives were just being redied for the harvest, and the day was beautiful.
That said, September in the Fall would be my pick for the best time to go, followed by April or May. If you are taking a day trip coming from the south, you'll change trains in La Spezia. Be sure to check the current weather below; the disadvantage to a Cinque Terre trip in the off season is the possibility of rain, which makes the trails a bit slipery.
The data below represents the detailed weather over the next two days from La Spezia, the province of the Cinque Terre.
