Conditions at Bournemouth in January
January: The Peak of the Winter Surge
January is Bournemouth's heaviest window on paper, with average swell peaking at 1.5m (5ft) and mean periods reaching 7.8s. The wave rose is dominated by WSW (21.6%) and SW (17.6%) swell, while direct SE/SSE/S/SSW energy makes up around 15% of the month's wave directions. In practice that means the bay is rarely flat, but the fetch is often too westerly and the accompanying wind too onshore. Wind conditions show WSW and SW winds combining for 25.7% of the time, and only 18% of hours blow from an offshore N/NNE/NW/NNW direction. Air temperatures average 7.7°C and water temps sit at 9.0°C, with 2.86 mm/day of rain feeding the frontal buzz. The period is only 7-8s, so it is punchy windswell rather than deep-ocean groundswell, but a ridge of high pressure can still turn an average, lumpy bank into a clean, shoulder-high beast.
