Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.
Water temperature data for this location is gathered from various sources, including buoys and satellite sea and ocean surface maps provided by the NOAA agency. We also incorporate data from local authorities in each specific location worldwide to ensure more accurate temperature readings.
Annual Water Temperature Overview by Month
Monthly Water Temp Ranges
Annual Water Temperature Trend
Strathmere is a small barrier-island community on New Jersey’s southern shore, known for its long, relatively undeveloped beaches and proximity to Corson’s Inlet State Park and the back-bay marshes. Water temperatures around Strathmere follow a typical mid-Atlantic seasonal pattern, generally ranging from about 2–8 °C in winter months to roughly 6–15 °C in spring. Summer brings the warmest conditions, with sea temperatures commonly between 18–25 °C on calm, sunny days, while autumn waters gradually cool to approximately 12–20 °C. Local variability is strong: shallow back bays warm and cool more quickly than the Atlantic, and onshore winds, tides and storms can change surface temperatures by several degrees over short distances and timescales.

Swimming Conditions
Swimming and beach holidays at Strathmere appeal to visitors seeking quieter shore experiences with access to both open-ocean surf and sheltered bay waters. Lifeguards are typically on duty during the core summer season at designated beach patrol points, but outside those hours swimmers should be cautious and observe posted flags and advisories. The ocean side offers moderate surf and the possibility of rip currents, so stronger swimmers should choose monitored areas; the back bays provide gentler conditions suitable for children, wading and paddle sports. Because spring and early autumn water temperatures can be cool for prolonged swims, many visitors plan beach activities for the warmest summer months or bring wetsuits for shoulder-season outings. Amenities are modest compared with larger resort towns, which helps preserve a more natural, family-oriented atmosphere for a beach-focused holiday.
