*** Forecast - Our water temperature forecast
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.

Location & Local Information
Rīga (in Latvian: Rīga) is situated where the Daugava River meets the Gulf of Rīga and contains several inland waters such as Ķīšezers and smaller lakes and ponds. Water temperatures in these lakes vary strongly by season: in winter (December–February) surfaces are typically at or close to 0 °C (32 °F) and often frozen; spring (March–May) sees a rise from about 1–12 °C (34–54 °F) as ice melts; summer (June–August) is the warmest period, with typical lake surface temperatures around 17–24 °C (63–75 °F), occasionally reaching 25 °C (77 °F) during hot spells; autumn (September–November) cools again to roughly 8–14 °C (46–57 °F) before approaching freezing by late November.
Swimming is generally allowed in Rīga at designated bathing beaches and monitored lake sites during the official bathing season, when authorities test water quality and lifeguards may be on duty. The main constraints are water quality, local safety (currents, boat traffic on the Daugava), and ice cover in winter. Open-water swimming outside supervised areas is possible but requires caution and awareness of water cleanliness and sudden temperature drops. Ice swimming is practiced by some locals as a seasonal activity, but it is only safe with proper supervision and equipment due to the risks of hypothermia and unstable ice.
