Mountains back thecoastline to the north. San Remo is about 60 n mi southwest of Genoa and is the chief resort forthis part of the Italian Riveria known as Riviera di Fiori. MonteSignone (4258 ft) located about 3 n mi north-northwest of the portdominates the landscape. Harbor as Haven Harbor as Haven The harbor is man-made. Its outer limits are defined by eastern andwestern breakwaters. Local port authories stated, during interviews inAugust 1987, that berthing for U.S. Navy ships was not available. Ifthis situation were to change, berths would be available on the innerside of the west breakwater and on the north mole inside the westernbreakwater. Maximum alongside depths are 12 to 14 ft (3.6 to 4.6 m).The entrance depth is approximately 18 ft (5.5 m) and width is about 100 ft (30 m). The harbor is very congested and small boats may be required to med moor. Fleet landing is located near the Port Captain's Office on the forwardend of the north mole. The inner harbor is exposed to easterly winds which will affect berthedships. However, vessels can ride out the heavy weather by doubling linesor employing other mooring tactics. Vessels are not required to sortieunder high wind conditions. Anchorage assignments are established by the Italian Navy. There are two anchorage areas, one about 3/4 n mi west of the entrance and the otherabout 3/4 n mi east of the entrance. Holding conditions are good in mudand sand bottoms. The anchorages are fully exposed to winds and wavesfrom the east clockwise through west. The most hazardous conditions are caused by heavy southwesterly swellcombined with local wind waves. Currents and Tides Currents and Tides Currents at San Remo are weak; limited to a 1/2 kt westward settingcurrent. Tides are negligible. Visibility Visibility Visibility at San Remo is generally good. During the warm season, nightand early morning visiblity is frequently reduced to 1 to 2 n mi inhaze/fog. During wintertime, reduction to visibility typically occursduring cloudy, rainy Genoa low events. Hazardous Conditions: Spring Hazardous Conditions: Spring Early spring weather at San Remo is similar to that of winter, butquickly moderates as the season progresses. Although Genoa lows canoccur in any month, strongest spring events are in March and April.Southwesterly winds are possible throughout the season, but strongestare expected in March/April. Because late winter/early spring is aperiod of maximum frequency for Mistral winds, southwesterly windsfrom Mistrals are also more frequent. By the end of May, southwesterlywinds are rare and of short duration. Thunderstorms are most likely with development of secondary frontsduring strong Genoa low events. Wind chill can still be a factor through mid-April. Hazardous Conditions: Summer Hazardous Conditions: Summer Summer is a season of relatively settled weather. Southwesterly wind events are rare and of short duration. A sea/land breeze regime isevident. Evening through early morning, winds blow from north clockwisethrough south and in afternoon from southeast to south. Harboroperations are usually not affected. Thunderstorms occur, but are usually widely scattered. Hazardous Conditions: Autumn Hazardous Conditions: Autumn Autumn usually lasts only for the month of October and is characterizedby an abrupt change from settled summer-type weather to stormywinter-type weather by month's end. Southwesterly wind frequencyincreases abruptly through the month as does Genoa low cyclogenesis. Hazardous Conditions: Winter Hazardous Conditions: Winter Winter conditions are wet and cool with frequent periods of squally,blustery weather associated with Genoa lows. With each low, severalperiods of bad weather are likely to occur. This is because the low maybe slow to move and secondary lows or troughs have a tendency to form. Strongest wind events at San Remo occur with the southwest windsresulting from Mistral events. Mistral winds can reach 34 to 47 kt(force 8-9) during strong outbreaks and combined sea and swell wavescan reach 13 to 16 ft (4-5 m) in open waters. Genoa low easterly winds are the most common cause of inclement weatherat San Remo. They are usually accompanied by overcast skies, rainy weatherand generate swell which passes through the port entrance into the mainharbor. Small boat runs to/from anchorages may be adversely affected. The most frequent wind direction in the early morning is northerly,becoming southeasterly or southwesterly in the afternoon, averagingabout 7 kt with little diurnal change in speed. Southerly winds and waves are rare, and are caused by depressions movinginto the Ligurian Sea or across Corsica into Italy. At the anchorages,the resulting swell is generally more of a problem than the wind. Swellseldom exceeds 6 ft (2 m) but it may persist for 2 or 3 days. If itpersists after the wind becomes easterly, then swell waves and sea wavescombine for cross seas. Anchored vessels may experience excessive rollingin this situation. Below freezing temps are uncommon but, when combined with high winds, cancause hazardous wind chill for personnel working in exposed areas. Protective/Mitigating Measures: Moving to a New Anchorage Protective/Mitigating Measures: Moving to a New Anchorage Most protected anchorage (mooring to buoys) is in Villefrance.Anchorage at Point Portofino 15 n mi southeast of Genoa is also wellprotected. There is little protection available outside of harborsalong the local coastal areas of Italy and France. During southwesterly winds from Mistral events, moving a short distancenortheastward along the coast will likely give reduced winds and seas butmaybe not swell. For Genoa low winds, moving southwestward is recommended. Protective/Mitigating Measures: Sortie/Remain in Port Protective/Mitigating Measures: Sortie/Remain in Port If berthed, doubling of mooring lines may be all that is needed duringhigh winds. Note that San Remo, crowded with private boats, is busy andcluttered. Protective/Mitigating Measures: Scheduling Protective/Mitigating Measures: Scheduling In warmer months, sea breeze is a daily occurrence. 10-15 kt windsprevail from noon to late evening. Operations requiring light/calmwinds should be done in morning hours. Harbor Protection Harbor Protection Wind and Weather San Remo is located in the overlapping areas between two well knownhazardous weather patterns. It is east of the region of strongestMistrals and west of the area of maximum impact of Genoa lows. Howeverit can, at times, experience weather associated with either of theseevents. Genoa low conditions usually are northeast to east winds 20 ktwith 40 kt max. Mistral conditions consist of west to southwest windswith max 50 kt winds and 20 ft (6 m) waves. Southwesterly conditionsalso occur with the passage of fronts associated with Genoa lows. During the warmer months, a daily southerly sea breeze develops.Typically, it peaks in mid-afternoon at 10-15 kt, but can reach28-33 kt, and may necessitate canceling small boat operations. Waves Except for waves from the east, the inner harbor is protected from opensea waves by the two breakwaters. Easterly winds will result in a lowswell entering the harbor and affecting the area around the north andsouth mole. The affects are minimal, but may result in harbor officialsrequiring special ship handling and berthing procedures. Vessels at anchor in the two primary anchorages outside the breakwaterare exposed to the open sea wave action. Under extreme southwesterlywind conditions, combined swell and sea heights reach 20 ft (6 m). Onrare occasions, southerly swell of 5 to 6 ft (2 m) affects the anchorageareas. Southerly swell events may persist for 2 to 3 days and typicallyresult in local wind and swell direction becoming out of phase. Wind direction may differ with swell direction by 45 to 90 degrees, causing excessive ship rolling. Local Hazardous Weather Conditions Local Hazardous Weather Conditions For Genoa lows:Onset of a Genoa low is signalled by strong west to northwest windsaloft over the Gulf of Lion a day or two before onset. Surface pressure falls over Gulf of Genoa and/or Po Valleyindicates the beginning stage of development. Commencement of Mistral winds in Gulf of Lion coincides with a closed lowdeveloping in the Gulf of Genoa. If winds have shifted to southwest then back to southeast, expect secondary frontal passage. If clouds start coming over mountains from north, southwest wind will shift to northerly and low is moving out. There are several guidelines regarding Genoa lows in theBrody and Nestor 'Regional Forecasting Aids for the Mediterranean Basin'. Most guidelines require a set ofweather charts for best results. Southwesterlies (From Mistral):A Mistral will likely be observed first in Marseille/Toulonbefore affecting San Remo. When a 10-mb pressure differenceexists between Toulon (high) and Nice (low), the Mistral willspread eastward; 2-mb difference between Marseille (high) andToulon (low), Mistral will cease near Toulon. Mistral: several forecaster hints and Mistral types are includedin the aforementioned Brody and Nestor publication.
