Tides on the River Hull do not follow normal patterns, the distance from the upper river to the Humber estuary at Sammy’s point greatly affects the tidal height on the river, ranging from negligible effect at the confluence with the Humber through a heavily modified tidal variation with 10 hours of ebb and 2 of flood in Beverley to negligible effect at Hempholme.
To calculate tidal predictions for Beverley, Hull Albert dock should be used as a reference.
- Low Water Beverley occurrs approximately at High Water Albert Dock.
- High water Beverley occurrs approximately 2 hours to 2 1/2 hours after HW Albert Dock.
- River height will start to rise before the flood starts, levels can rise by up to 6″ before the ebb stops.
- Maximum river height (High tide) will occurr before slack water, levels will start to drop before the flood stops.
- Tidal heights can only be predicted by comparing the predicted height in Hull with the trend observed on the river.
River heights vary depending on rainfall and other factors. There is a broadly seasonal variation with minimum levels in the river usually occurring from late September through October and possibly into early November.
The best guide to river height is to look at the recent records available from the Environment agency website, and compare this with current rainfall and tidal predictions.
Current weather in Beverley can be obtained from a variety of sources, the Met office site is generally reliable for present weather and predictions. This forecast is adequate for navigation on the River Hull and Driffield Navigation; The Met Office shipping and inshore weather forecasts should be consulted in planning trips across the Humber.
