Storm Gloria as the Dragonera buoy, west of Mallorca, felt it, 19 to 20 January 2020. The day began with a calm sea of under a metre. Late in the morning a strong northeasterly wind set in within two hours and held at 16 to 17 m/s, with gusts of 27 m/s, while the air pressure stayed near 1014 hPa: Gloria was a long fetch of wind between high pressure to the north and low pressure to the south. The waves built through the day and night to a significant wave height of 7.8 metres at 03:00, when the buoy also recorded a single wave of 16.0 metres, and the period lengthened from 4 to 12 seconds.
