Analysis of Wind Characteristics in Tuban Regency Waters, East Java: Implications for Small-Scale Fishery Operations

Abstract

Wind is a critical meteorological parameter influencing sea conditions, fishing vessel safety, and the effectiveness of capture fisheries in coastal waters. This study analyzes wind characteristics in the waters of Tuban Regency, East Java, Indonesia, based on observational data from the BMKG Maritime Meteorological Station Perak Surabaya. Wind speed and direction data from October to December 2025 were analyzed using descriptive statistics and windrose diagrams to identify dominant wind patterns and their implications for small-scale fisheries. The results show that wind speeds generally ranged from 2 to 6 knots, with occasional increases to 10-12 knots, particularly from late November to early December. The dominant wind directions originated from the west (W), southwest (SW), and south (S) sectors, consistent with the seasonal monsoon transition. The average wind speed of 5 -6 knots is categorized as light to moderate, which is generally safe for small-scale fishing operations. However, speed fluctuations exceeding 10 knots require adaptive fishing strategies. This study provides baseline information for improving weather-based fisheries management and safety planning in the southern Java Sea region
