Conditions at Telescopes in December

December: Low Season Lull

December is the low point of the year for surf quality at Telescopes. Ideal wind bottoms out at 22%, and the wind rose is dominated by NW (19.3%), WNW (17.1%), and NNW (16.1%)-all of which blow onshore or cross-onshore into this west-facing reef. The swell is still present, averaging 3ft (1.0m) at 12.6 seconds, with SSW (56%) and SW (26%) the main energy sources. A few WSW (7%) and W (1.5%) swells sneak in with good direction, but they are often accompanied by the monsoon's wet, windy weather. Rainfall averages 11.15 mm/day and water temperature is 28.9°C. For the dedicated crew, the combination of a strong W/SW groundswell and a rare island land breeze can produce the odd fun wave, but December is mostly about waiting for the northwest monsoon to ease.
