Conditions at Esposende in March
March: Transitional Power
March is the beginning of the end of the biggest winter surf, but there is still a lot of muscle in the ocean. Average swell height sits at 2.4m (7.9ft) with an average period of 12.0s, so the majority of waves are still in the powerful, long-period category. The swell rose shows an incredibly consistent supply from WNW (19.4%), NW (19.0%), NNW (11.1%) and W (7.7%), giving Esposende excellent exposure through the whole month.
The trade-off is wind quality. The ideal wind percentage drops to 41% as the spring transition begins, with NNW winds now at 17.8% and NW at 7.7%. This is the first real sign of the nortada, but it is not yet dominant; mornings can still produce offshore easterly flow and glassy conditions. Water temp rises to 13.7°C, air averages 11.9°C, and rain is still fairly frequent. A 4/3 wetsuit remains the sensible call, though sunny afternoons start to feel more like spring.
