T-Street seasonal overview
T-Street in the United States offers relatively consistent surf conditions throughout the year, with ground swell dominating the wave activity. The best months for surfing at this spot are generally from April to September, when ground swell presence is highest (93% to 98%) and wind conditions are relatively more favorable compared to other months. May stands out with the largest mean swell size (1.0m) and a decent 36% chance of good wind conditions, making it one of the top months for surfers. August also provides the highest likelihood of favorable winds (46%) despite slightly smaller swells (0.8m). The winter months, particularly November and December, see a drop in ground swell consistency (79% to 89%) and significantly worse wind conditions (78% to 79% bad winds), making them less ideal for surfing. While swells remain present year-round, surfers should prioritize late spring through early fall for the best combination of reliable swell and manageable winds. Summer months like June and July maintain strong ground swell dominance but still suffer from poor wind conditions about two-thirds of the time, requiring careful timing for optimal sessions. Overall, T-Street is a fairly consistent year-round break, but late spring and summer provide the most balanced conditions for quality surfing.

Conditions at T-Street in December
December at T-Street typically offers decent surf conditions with a mix of small to moderate swells and variable winds. The average swell height is 0.8m with a solid 14.5-second period, indicating consistent, well-spaced waves that hold shape. Most swell energy comes from the WSW, W, and SW directions, with the majority of waves ranging between 0.5m and 1.5m—ideal for intermediate surfers. Larger swells (1.5m+) are rare but present occasionally, mainly from the W and WSW. Wind conditions are a mixed bag, with only 22% of days offering ideal offshore or light winds (typically NE to E early in the day). The predominant winds are S to WSW, which can create onshore chop, especially at higher speeds (10-30kph). Mornings often provide the cleanest sessions before winds pick up. Expect a fair number of rideable days, though quality depends on wind alignment. Winter swells bring consistency, but wind management is key for scoring the best waves.
