Question:
Table VII in Vol 27 records average wind direction frequencies at 09:00 GMT at seven coastal stations. The table has an entry for June and a merged entry covering July and August together, but no separate July row. Estimate the wind frequency for July alone by linear interpolation between June and the start of the July–August merged period.

Answer concisely. Cite the row/cell/section you used. State your final numerical answer clearly.
