Tamri seasonal overview
Best Surf Season (October - March)
The North Atlantic comes alive during the autumn and winter months, sending consistent, powerful groundswells from the W to NNW quadrants directly into Tamri's NW-facing beach. Average swell heights hover around 2.1 to 2.3m with long periods averaging 12-13 seconds, producing pumping, firing waves that can easily reach XL proportions when the strongest storms align. The trade-off is a healthy dose of onshore wind from the N-NW, but the percentage of ideal offshore flow (W, WSW, SW, SSW) peaks during these months—especially in December, January, and November when it exceeds 44%. This is the window for top-tier surf, with clean, lined-up faces and light offshore conditions often accompanying high-pressure setups over the Sahara. If you can only plan one trip, aim for November through February.
Fair Surf Season (April & September)
These transitional months offer a mixed bag. April sees the last of the winter power—average swell height remains a solid 2.1m but the period drops to 10.8s and ideal wind percentages fall sharply to 19%. The dominant swell direction shifts strongly towards NNW, which is still a good angle for Tamri, but the wind becomes increasingly dominated by N-NW flow, making clean conditions rarer. September brings a slight rebound in period (10.0s) after the summer lull, but swell heights average just 1.6m. Ideal wind percentages climb to 18%, offering occasional windows of fun, rippable waves on the smaller side. These months are for the dedicated surfer willing to pick their days.
Low Surf Season (May - August)
From May through August, Tamri experiences its lowest surf activity. The North Atlantic storm track shifts north, resulting in average swell heights between 1.6 and 1.9m and periods as low as 7.6 to 9.3 seconds—generally small, groveling conditions. The wind pattern is dominated by strong N to NNW flow, which blows directly onshore at Tamri, ruining wave quality. Ideal offshore wind (from the SW sector) occurs only 8-13% of the time. Swell direction is overwhelmingly from the NNW (over 90% of total swell in July and August), which, while technically in the optimal range, is accompanied by onshore winds that chop up the waves. This is the quiet season, best suited for beginners or those seeking a beach holiday rather than serious surf.

Conditions at Tamri in September
September: First Signs of Renewal
September shows the first signs of the approaching winter season. Average swell height is 1.6m (still low), but the period increases to 10.0s, indicating a return of longer-period swell. The dominant swell direction is NNW (74.9%), with a notable NW component (15.2%). The wind pattern begins to shift: N (26.7%) and NNW (22.8%) still dominate, but there are slight increases in offshore winds from the SE-SW sector. Ideal wind percentage climbs to 18%. Wave heights are mostly in the 1-1.5m and 1.5-2m ranges (27.9% and 26.8% from NNW). While still small, the longer period and occasional offshore wind can produce clean, fun surf on the better days. September is the transitional month that hints at what's to come.
