WEATHER BULLETIN FOR SHIPS
SURINAME COAST & THE GUIANAS | 05N–15N / 45W–60W
🚨 PART I: STORM WARNING
NO STORM WARNING. No storm warning is currently active for the forecast area.
🌐 PART II: SYNOPTIC OVERVIEW — Situation 1000UTC August 10, 2026
The ITCZ extends from 11°N/45°W to 12°N/60°W, remaining north of Suriname. A tropical wave near 49–50°W is moving westward at 10–15 kt and is currently surrounded by Saharan Air, limiting significant convection. Moderate to fresh easterly trade winds prevail across the region, while the Atlantic ridge dominates the overall circulation pattern.
🌧 Saharan Dust: Saharan Air is currently surrounding the tropical wave near 49–50°W, contributing to a relatively dry and stable mid-level environment and suppressing significant deep convection. As the Saharan Air moves westward, it may temporarily limit convective development over the region. If dust concentrations increase over Suriname, hazy conditions and reduced visibility may occur.
⛵ PART III: WEATHER FORECAST — 1200UTC August 10, 2026 to 1200UTC August 11, 2026
A warm and humid weather pattern is expected over Suriname. The ITCZ remains north of the country, extending from approximately 11°N/45°W to 12°N/60°W. A tropical wave near 49–50°W is moving westward and is surrounded by Saharan Air, which is currently limiting significant deep convection. Nevertheless, the proximity of the ITCZ will maintain sufficient low-level moisture for the development of scattered showers and isolated thunderstorms, particularly during the afternoon and evening. Moderate to fresh easterly trade winds are expected to prevail.
