Libyan Meteorology Issues Maritime Warning: Active Winds Threaten Coastal Waters

Wind Speeds Reaching 25 Knots Prompt Urgent Advisory for Mariners

The Libyan National Meteorological Center (LNMC) has issued a maritime warning for active northwesterly winds affecting coastal areas from Derna to Tobruk, with wind speeds expected to reach up to 25 knots. The warning, released Thursday morning, urges fishermen and maritime operators to exercise caution along the eastern coastline.

According to the LNMC's marine fishing bulletin, wave heights along the affected stretch are forecast to remain below 1.5 meters, but the combination of gusty winds and choppy sea conditions poses risks for small vessels and fishing boats operating offshore.

Winds Affecting Multiple Coastal Zones

The warning covers a broad sweep of Libya's Mediterranean coastline. The National Meteorological Center reported that northwesterly winds will be active today along the coast from Derna to Tobruk, with speeds reaching up to 25 knots. Meanwhile, separate advisories note that Al-Shalluq winds — a local term for hot, dry southerly winds — will be active from Zuwara to Tripoli, shifting to strong conditions by evening on the coast from Sirte to Benghazi.

These conditions are expected to create choppy seas and reduced visibility in certain areas, particularly near Derna and Tobruk where horizontal visibility may become partially limited due to wind-driven sea spray and dust.

Wave Heights and Sea Conditions

According to the LNMC's marine fishing bulletin, wave heights along the affected coastline are not expected to exceed 1.5 meters. However, the combination of northwesterly winds reaching 25 knots and moderate swell creates hazardous conditions for small fishing vessels and recreational boats.

Sea surface temperatures along the Libyan coast currently range between 25 and 28 degrees Celsius, typical for this time of year. Horizontal visibility is expected to remain good across most coastal areas, though it may become moderate along the Derna and Tobruk coastlines due to wind-driven sea spray and suspended dust.

Affected Areas: From Derna to Tobruk, Zuwara to Tripoli

The National Meteorological Center's marine bulletin identifies two primary zones of concern. The first stretches from Derna to Tobruk in eastern Libya, where northwesterly winds will be most active, reaching speeds of up to 25 knots. The second zone covers the western coast from Zuwara to Tripoli, where Al-Shallog winds — hot, dry southerly winds — are expected to become active before shifting to strong conditions by Friday evening along the coast from Sirte to Benghazi.

Wave heights are forecast to remain under 1.5 meters across all affected areas, but the combination of gusty winds and moderate swell creates hazardous conditions for small fishing vessels and recreational boats operating near the shore.

Impact on Maritime Activities and Fishing Communities

Libya's fishing communities, particularly those operating out of Derna, Tobruk, and coastal towns between Zuwara and Tripoli, are directly affected by this warning. Small-scale fishing vessels — which make up the majority of Libya's fishing fleet — are most vulnerable to sudden changes in sea conditions. The LNMC's advisory serves as a critical safety measure for these operators, who often lack access to real-time weather monitoring equipment.

The warning also affects commercial shipping and port operations along the affected stretches of coastline. Port authorities in Tripoli, Misrata, and Benghazi are advised to monitor conditions closely, particularly as the Al-Shallog winds intensify along the central coast from Sirte to Benghazi by Friday evening.

Practical Advice for Mariners and Coastal Residents

For fishermen and boat operators along the affected coasts, the LNMC recommends the following precautions: monitor updated marine bulletins before departing, ensure all safety equipment is onboard and functional, avoid venturing beyond sheltered waters during the warning period, and maintain communication with port authorities. Small vessels should remain in port until conditions stabilize, particularly in the Derna-Tobruk and Zuwara-Tripoli zones where wind activity is expected to be strongest.

Coastal residents are advised to secure loose outdoor items that could be displaced by strong winds and to avoid swimming in areas where rip currents may develop due to the active sea conditions. The warning is expected to remain in effect through Friday evening, with conditions gradually improving over the weekend.
