Description
Daily maximum wind and wave conditions for the summer months (June-August) of 2023-2026 in the Gulf of Gdansk, southern Baltic Sea, at 54.38 N, 19.02 E (nearshore point between Mikoszewo and Jantar, Poland). 318 daily records with columns: date, wind_speed_10m_max_ms, wind_gusts_10m_max_ms, wind_direction_10m_dominant_deg, wave_height_max_m, wave_period_max_s. Compiled from the Open-Meteo historical weather and marine APIs; the 2026 season is covered through 12 July 2026 (archive lag). The series places the storm Bernadette event of 8 July 2026 in its recent summer climatological context: its daily maximum significant wave height of 3.66 m is the highest summer value in this four-year series by a wide margin (next highest: 2.46 m on 11 July 2025). Winter-strength wave conditions in high summer are rare on this stretch of coast. The data underpins the storm analysis and amber wash-up forecasting context published at ambermap.com (see Related Links). Hourly time series for the storm itself are available in companion records: Gulf of Gdansk (DOI 10.5281/zenodo.21427383) and the open Polish coast at Ustka (DOI 10.23728/b2share.c097m-5pg84).
