Reading the tide at Kemah

These times come from the NOAA CO-OPS station at Clear Lake, measured against mean lower low water (MLLW) — the datum every US chart uses, so a 1.5 ft prediction means a foot and a half above the average lowest tide, not above the bottom. Wind and pressure shift the real water level either side of the prediction: a hard onshore blow stacks water up and a strong offshore wind can pull a low tide well below what the table says.

Local tip: Wind matters more than the moon up here — a sustained southeast breeze stacks water into the upper bay while a norther drains it, and calm summer mornings give the flattest water of the day before the sea breeze fills in.

For fishing, the times in the table matter less than what happens between them. Water moving is what turns the bite on, and the strongest flow is roughly midway between a high and a low — so the two hours either side of that midpoint usually beat slack water at either end, particularly around sailing and boating.

Kemah tide questions

What time is high tide at Kemah today?
High tide at Kemah · Clear Lake is at 7:31 AM (1.1 ft), predicted by NOAA at Clear Lake. Wind can shift the actual water level either side of the prediction.
What time is low tide at Kemah today?
Low tide at Kemah · Clear Lake is at 9:18 PM (-0.1 ft). A strong offshore wind can pull the water lower than predicted, which matters on shallow flats and at boat ramps.
How big is the tide at Kemah?
Today's range at Kemah · Clear Lake is about 1.1 ft. Florida's Gulf coast runs a moderate range that varies a lot by latitude — roughly two feet through the Sarasota and Charlotte Harbor beaches, building to four or five up the Nature Coast and into the Big Bend. Either way the range grows around the new and full moon — those spring tides move noticeably more water.
Which tide is best for fishing Kemah?
Moving water beats slack water almost everywhere. The strongest current runs roughly midway between a high and a low, so plan the two hours either side of that rather than the exact turn. First and last light overlapping a moving tide is the classic window.
