5. Cape Verde weather service and bulletins

Instituto Nacional de Meteorologia e Geofísica (INMG) provides the official Cabo Verde forecast context. Marine bulletins are issued for the full archipelago as well as for specific regions.

For Sal, the most relevant reference is the Barlavento Oriental bulletin (Sal / Boa Vista), complemented by the general archipelago bulletin for broader context.

Source: INMG official marine weather bulletins.

Barlavento Occidental: western windward sector.
Barlavento Oriental: eastern windward sector, including Sal and Boa Vista.
Sotavento: southern / leeward sector.
Typical bulletin content: wind direction, Beaufort range, wave height and short regional outlook.
Use on this page: official regional reality check against the model view for Sal.
Latest available bulletins: hosted locally for stability and direct access.

6. Local wind interpretation · Harrys’ Point · N16°35.4′ W022°53.4′

This section is about local reading, not about model output. Airport observations are useful, but Harrys’ Point must be interpreted with coastal acceleration, cape effects, shoreline geometry and local exposure in mind.

Source: local interpretation based on GVAC, OpenSeaMap, Windy, Windguru and PredictWind.

coastal acceleration cape effect local thermal influence airport ≠ spot
Reference point: Harrys’ Point is named after the famous and well-known singer-songwriter Harry Kaey.
Operational reading: Compare airport truth, synoptic setup and model background before judging the beach.
Map anchor: Use the local map position to keep the exposure and coastline geometry in mind.
Local convection: Small-scale thermal activity (e.g. dust devils) confirms local heating effects, but rarely alters the trade wind regime.

OpenSeaMap marker: Harrys’ Point is linked with an explicit map marker and centered map view.

Marine format: N16°35.4′ · W022°53.4′
Decimal: 16.590556, -22.889722

7. Numerical model guidance

Source: local JSON forecast package generated on the VPS from ECMWF IFS / ECWAM context. Model comparison (GFS, ICON Global) is planned for future integration.

Model comparison mindset

Use ECMWF as primary reference; wave context is provided by ECWAM. GFS and ICON Global will be added for structured comparison. Differences matter more than slogans.

ECMWF / local point forecast

Primary local model guidance for Harrys’ Point and Matts’ Point. Harrys’ Point is derived through bilinear interpolation from the surrounding model grid, while Matts’ Point currently uses a sea-side coastal override.

8. Saharan dust

Dust matters for visibility, air quality and for the overall character of the day, even when the wind itself looks straightforward.

Source: ECMWF CAMS aerosol products and AEMET dust products.

Operational effect: reduced visibility and a different visual feel to the atmosphere.
Interpretation effect: useful context when the day feels flatter, dirtier or less clear than the wind charts alone suggest.
Workflow: check dust context deliberately alongside the synoptic and model view.

9. Visual observations · Sal
