Myrtle Beach visitors planning a June trip often center their activities around the ocean, and understanding the water temperature is the first step to planning a successful day. During this month, the coastal waters transition from the cool embrace of spring to a welcoming warmth that encourages long swims and extended sessions on the sandbar. The average water temperature in Myrtle Beach in June typically ranges between 73°F (23°C) and 78°F (26°C), creating conditions that are generally comfortable for a wide range of aquatic activities.
Early June vs. Late June Temperature Shifts
When examining the specific data for water temperature in Myrtle Beach in June, it is important to distinguish between the beginning and the end of the month. At the start of June, the ocean often reflects the lingering coolness of spring, with temperatures possibly dipping to the low 70s. As the month progresses toward the summer solstice, the daily sunshine hours increase significantly, and the sea warms steadily. By the final week of June, it is not uncommon for the water to reach the upper end of the spectrum, hitting 78°F or even touching 80°F on particularly hot days.
Factors Influencing Daily Variations
While the monthly average provides a reliable baseline, the actual water temperature in Myrtle Beach in June can fluctuate based on specific meteorological conditions. A persistent southerly or westerly wind can push warmer surface water toward the shore, creating a pleasant bathing experience. Conversely, a bout of cooler air or a passing cold front can temporarily chill the shallows, making the water feel brisker than the calendar date suggests. Additionally, recent rainfall can cause freshwater runoff from the land, which mixes with the saltwater and lowers the overall temperature in inlets and near river mouths.
Activities Best Suited for June Waters
The temperature range found in June makes Myrtle Beach exceptionally versatile for water-based recreation. The warmth is sufficient for body surfing and paddleboarding without the intense heat that characterizes mid-July and August. Swimmers can enjoy extended periods in the water without the risk of chilling that occurs in the early spring months. This ideal thermal window also makes it a prime time for anglers targeting species like red drum and flounder, who are active in the warmer water but not yet dispersed to the extreme depths of peak summer.
Stand-up paddleboarding (SUP) for exploring calm inlets.
Body surfing and skimboarding in the shallows.
Surf fishing from the shoreline or jetties.
Kayaking trips to observe coastal wildlife.
Snorkeling to view the local marine ecosystem.
Relaxing swims far from the crowded shore breaks.
What to Wear and Pack Preparing for the water temperature in Myrtle Beach in June involves balancing comfort and protection. While the air temperatures can be warm, the ocean breeze has a cooling effect, making a light layer essential. A high-quality swimsuit is the foundation, but packing a thin rash guard or a light wetsuit top is highly recommended. These items provide a barrier against the cooler water in the morning and protect against unexpected gusts of wind. Sunscreen is non-negotiable; the UV index is high in June, and reflection off the water intensifies exposure. Comparing June to Adjacent Months

To truly appreciate the water temperature in Myrtle Beach in June, it helps to compare it to the surrounding months. In May, the water is often still in the 60s, requiring a thick wetsuit for comfort and limiting the duration of immersion. July and August, while warmer, can sometimes see temperatures climb into the low 80s, which can be oppressively hot for some visitors and increase the likelihood of jellyfish sightings. June strikes a "Goldilocks" balance—warm enough for enjoyable swimming but not so hot that it becomes uncomfortable, representing the sweet spot for a beach holiday.
