Are you planning a trip to Puerto Penasco?
As beautiful as the beaches are, it’s important to be aware of jellyfish and stingray season to ensure a safe and enjoyable visit.
Here’s everything you need to know to stay safe and make the most of your beach time.
When is Jellyfish and Stingray Season?
Jellyfish and Stingray Season:
Typically, jellyfish and stingray season in Puerto Penasco runs from May to October.
During this time, the warmer waters attract these sea creatures closer to the shore. More activity is noted from spring to early summer.
- May: Average sea temperature around 74°F. Ideal for swimming. Small jellyfish often start to appear near Laguna Shores.
- June–August: Water peaks between 80°F–90°F; sightings of both creatures spike, with July usually the high point for jellyfish numbers.
- September–October: Water remains warm (77°F–84°F), but as cooler weather begin, activity gradually tapers off.

How to Stay Safe
Protective Gear:
Consider wearing protective gear like water shoes and wetsuits to minimize the risk of stings and burns.
Stingrays will usually only sting when disturbed or stepped on by unaware swimmers.
- Shuffle Your Feet: When walking in shallow water, shuffle your feet to alert stingrays of your presence. This gives them time to get away.
- Look for jellyfish in the water: If you see jellyfish in the ocean just stay out of the water in that specific area.
- Check Beach Conditions: Monitor water temperature and be mindful of any warnings about jellyfish or stingray activity.
What to Do If Stung
Jellyfish Stings:
- Rinse with Vinegar: If stung by a jellyfish, rinse the affected area with vinegar to neutralize the toxins. Do not rub the area, it can make it worse.
- Remove Tentacles: Use a pair of tweezers to carefully remove any remaining tentacles.
- Avoid Dead Jellyfish: Even dead jellyfish can sting. Avoid touching them if you see them washed up on the shore.
- Meat tenderizer: Try soaking the wound in sea water with unflavored meat tenderizer and the jellyfish bits should dissolve.
- Seek Medical Help: If symptoms persist or the sting is severe, seek medical attention immediately.
Stingray Stings:
Contrary to popular belief, peeing on a stingray wound will not help.
- Hot Water: Soak the sting in the hottest water you can tolerate as quickly as possible to alleviate pain.
- Clean the Wound: Clean the wound thoroughly to prevent infection.
- Vinegar or Baking Soda: You can also rinse the wound with vinegar or apply a baking soda paste.
- Medical Assistance: Stingray stings can become infected, so it’s important to seek medical help.

Stingrays
What are they?
Round stingrays are the most common in Puerto Penasco.
They vary in color from tan to brown to gray and from plain to spotted or blotchy with varying pattern shades giving them a spotted appearance.
They range from just a few inches in diameter as a youngster to as much as 12″ as a full grown adult.
Stingrays generally aren’t dangerous — in fact, they have a reputation for being gentle. They are harmless bottom feeders, they eat any food waste that would deteriorate the water quality.
Are they dangerous?
Although stingrays do not attack people, the tail spines can cause painful wounds if stepped upon or handled without caution.
However painful the sting, they are usually little threat to the long term health of the wounded.
Jellyfish
What are they?
If you see a gelatinous blue blob on the sand while you’re walking down the beach or in the ocean while you’re swimming, avoid it and keep your eyes open for more.
Most of jellyfish look like small, clear blobs with tentacles hanging beneath them.
Are they dangerous?
While jellyfish stings are painful, most are not emergencies. Expect pain, red marks, itching, numbness, or tingling with a typical sting.
Once you’ve been stung, for some people it can take a long time for the pain to dissipate but others seem to be hardly bothered at all.
