Our first trip to Puerto Penasco about 6 years ago, was in June. The heat and humidity didn't deter us from this vacation destination. We just avoided summer, and especially enjoy the Spring and Fall.
I'd been looking to be anywhere but home this summer, so when the opportunity arose to spend 4 nights in Rocky Point, we took it! I knew an air-conditioned condo on the beach would make the trip bearable.
When I first got out of the car to register at the Sonoran Sun Resort, my eyeglasses immediately fogged up. The humidity was stifling!
After we lugged all of our stuff from the car and unpacked, we headed for the beach. The ocean water was so warm, we could walk in without hesitation. In fact, it was almost grossly warm. Remember how there are warm spots and cold spots when swimming in the ocean? We especially noticed at low tide, the cold spots were warm and the warm spots were hot! It was quite eerie.
A couple of storms on Friday and Saturday night cooled the water quite nicely. It was still very warm, but a little more refreshing. The lights went out for about 1/2 hour on Friday night and I was very glad I had remembered to pack a flashlight.
We enjoyed sitting on the balcony watching the fascinating lightning show. No rain arrived until after we'd gone to bed, and had stopped by morning. The waves were nice for body surfing, which is unusual, at least during other times of the year. Normally, the waves are very small on the beaches of Puerto Penasco.
We ventured into town a couple of times for Chino's especial quesadillas and a little shopping. It was too hot for much wandering around downtown, but it was quite crowded nonetheless. Most restaurants have air conditioning, but the shops are mostly open-air.
If you're not used to the heat, I'd suggest going to Rocky Point anytime but June-August. The beach and pools were busy and the topic of conversation in the elevators was always the heat!
