🌀 Swell
🌊N to NNE long-period swell, 1.5–2.2 m, period 11–13 s, arriving in the northern half of the area during the first part of the period and spreading south toward the coastal waters overnight; underlying E–NE trade-wind sea, period 5–7 s

☀️ DAYTIME | NOVEMBER 11, 2026
💨Wind DirectionE to NE, becoming NE to ENE with the afternoon sea breeze
🌬Wind Speed15–24 km/h (8–13 kt), locally 24–30 km/h (13–16 kt) offshore and along exposed coastal sections in the afternoon, gusts 28–37 km/h (15–20 kt), locally 46 km/h (25 kt) near thundershowers (Beaufort scale 3–4)
🌊Wave DirectionNE to ENE, with a N to NNE swell component
📏Wave Height1.0–1.5 m in the coastal waters (slight to moderate); 0.5–1.0 m nearshore, locally higher at exposed open-coast sections and river mouths
👁VisibilityGood most of the time | In moderate showers: 5–8 km | In heavier thundershowers: 2–4 km for short periods
⛅WeatherPartly cloudy with isolated to scattered showers, mainly over the outer coastal waters near the ITCZ in the morning. During the afternoon convection develops mainly inland, with an isolated thundershower possible near the coast; mostly fair over the nearshore waters.
🌙 EVENING / NIGHT | NOVEMBER 11/12, 2026
💨Wind DirectionE to ENE, backing NE to ENE late at night
🌬Wind Speed9–19 km/h (5–10 kt) nearshore, 15–24 km/h (8–13 kt) farther offshore, gusts 28–37 km/h (15–20 kt) under showers (Beaufort scale 2–4)
🌊Wave DirectionNE to ENE; long-period N to NNE swell under-running the wind sea
📏Wave Height1.0–1.6 m in the coastal waters (slight to moderate), slowly increasing as the northerly swell arrives; 0.6–1.1 m nearshore
👁VisibilityMostly good; reducing to moderate (4–8 km) in showers and briefly poor (2–4 km) in heavier thundershowers
🌙WeatherPartly cloudy to cloudy with isolated to scattered showers over the coastal waters, and an isolated thundershower possible, mainly after midnight and towards early morning as land-breeze convergence and the nearby ITCZ act together.
🔭 OUTLOOK — Suriname Coast, November 12 to November 15, 2026
⛅ WeatherThu–Fri Nov 12–13: ITCZ remains near 06N–08N. E to NE winds offshore mostly 10–18 kt; long-period N–NNE swell peaks, with combined seas of 1.8–2.5 m offshore and 1.2–1.8 m in the coastal waters; isolated to scattered showers and isolated thundershowers, mainly near the coast at night and early morning. Fri–Sat Nov 13–14: The northerly swell slowly decays (1.5–2.0 m, period 10–12 s) while high pressure rebuilds north of the area, tightening the gradient and freshening the trades north of about 10N. Rainfall coverage trends steady to slightly lower. Sat–Sun Nov 14–15: Trade winds 15–20 kt offshore, wind sea becoming dominant again (E–NE 1.5–2.1 m); near the coast moderate seas of 1.0–1.5 m with isolated showers and good visibility outside precipitation.
💨 WindThu–Fri Nov 12–13: E–NE, coast 15–24 km/h (8–13 kt), offshore 19–33 km/h (10–18 kt), Bft 3–4 | Fri–Sat Nov 13–14: E–NE 24–33 km/h south of 10N, 28–37 km/h north of 10N (Bft 4–5) offshore, coast 15–28 km/h | Sat–Sun Nov 14–15: E–NE 28–37 km/h (15–20 kt, Bft 4–5) offshore, gusts to 46 km/h; coast 19–28 km/h
