What are summer temperatures in Paracas?
Temperatures are going to be similar to Lima. Low will be around 12C (55F) and high will no higher than 23C (75F). It will be windy as you're right on the coast. Most hotels have hot tubs, so make sure and check with Hacienda Bahia. If you're looking for a beach getaway with good temperatures I would probably suggest Mancora as a better option.
