Season by season
When to visit Weddell Sea
November–March for most Peninsula expeditions; routes and seasons vary. Rounded NASA POWER 2001–2020 daily model averages near Weddell Sea. Temperatures are mean daily highs/lows; precipitation is the mean monthly water-equivalent total, including snow where relevant. A coarse grid smooths coast, island and mountain differences; this is not a station observation or forecast. Conditions can still change sharply by elevation, coast and exposure, so use the chart for route timing and the current forecast for the day itself.
