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
Playa Guiones, on Costa Rica’s Nicoya Peninsula, has warm Pacific waters that are inviting year-round. Typical sea temperatures generally range between about 25 °C and 30 °C. During the drier months, when offshore swell is more consistent, water commonly warms toward the upper part of that range, often around 28–30 °C. In the wetter season temperatures tend to be a touch cooler, more often in the mid-20s to high-20s Celsius, roughly 25–28 °C. Daily and tidal variation is modest, so swimmers will usually feel pleasantly warm even when air temperatures dip, and the long sandy bottom of the beach helps the water retain heat compared with rockier shorelines.

Swimming Conditions
Swimming at Playa Guiones is a mix of relaxed ocean swims and active surf opportunities. The beach’s consistent waves and sandy profile make it a favorite with surfers, bodyboarders and open-water swimmers alike; on calmer days the shallow shore offers easy, waist-deep swimming, while larger swells create conditions better suited to experienced surfers. Currents and occasional rips can form, especially when the surf picks up, so assessing conditions before entering and choosing sheltered stretches or times of gentler tide will improve safety and enjoyment. The length of the beach also means plenty of room for families and lap-style swims, and the generally warm water temperature makes it pleasant to stay in the sea for extended periods during a beach holiday.
