Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 50°F (10°C) to 54°F (12°C). The water is slightly warmer, but still cool for most people. Swimming in such conditions is possible, but for most people, the time spent in the water should be limited to avoid hypothermia. Even experienced swimmers may feel discomfort if they stay in the water for too long. To improve comfort and safety, a wetsuit can be used.
It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

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
Samoa, California, sits on the narrow Samoa Peninsula at the mouth of Humboldt Bay on the northern Pacific coast of the United States. The marine environment is strongly influenced by the cold California Current and frequent coastal fog, so sea temperatures remain cool year‑round. Typical seasonal surface temperatures are roughly 9–11 °C in winter (December–February), about 10–12 °C in spring (March–May), warming to around 12–14 °C in summer (June–August) and settling to roughly 11–13 °C in autumn (September–November). On the warmest late‑summer days sheltered parts of the bay may approach 15 °C, but open ocean conditions are generally colder and vary with upwelling and weather patterns.

Swimming Conditions
Swimming and beach holidays in Samoa are therefore shaped by cool water and often brisk conditions. Open‑ocean bathing is feasible for brief swims but typically requires a wetsuit and experience with cold water and surf; rip currents, strong surf and limited lifeguard coverage are common concerns. Humboldt Bay and more sheltered inlets provide calmer water for paddling, beginner ocean swims in good weather and wildlife viewing, though temperatures remain cool. Visitors often combine beach walking, dune exploration and kayaking with short, protected swims in summer; for extended swimming or sunbathing, late summer and early autumn offer the mildest water, while adequate thermal protection and attention to local warnings are advisable year‑round.
