May sits at the turning point where Houston golf stops being comfortably mild and starts requiring real heat management. The average high climbs to 84°F — up 6°F from April — and the low holds at 69°F, meaning there's rarely a cool moment even at first light. With 21 precipitation days, May is tied for the wettest month of the year, so the forecast matters every single round. Wind backs off slightly from April's 14.4 mph peak to 13.4 mph, which helps a little, but conditions can shift quickly.
The 15°F daily swing between high and low gives morning rounds a genuine edge. Tee times before 9 AM put you in a different game than afternoon starts — cooler air, softer turf, and usually a better shot at beating the afternoon storm cells that build over the Gulf Coast this time of year. The Variable tier on this page is earned honestly.
Book the earliest available tee time — the gap between a 69°F low and 84°F high means conditions at 7 AM are genuinely different from those at noon, and afternoon convective storms are common enough in May that finishing 18 before 1 PM is worth planning around. With 21 precipitation days on the calendar, checking a short-range radar forecast the morning of your round is more useful than a week-out booking decision.

May is noticeably warmer and wetter than April, adding 6°F to the average high and two more precipitation days while shedding just 1 mph of peak wind, so the window of comfortable conditions narrows considerably. Heading into June, temperatures keep climbing another 5°F to an 89°F average high and the low rises to 74°F, making early-morning starts even more important. Precipitation eases only slightly in June (down one day to 20), so the rain risk doesn't meaningfully improve as summer arrives.

← April in Houston, TX • June in Houston, TX →
May averages 21 precipitation days, making it tied for the wettest month of the year in Houston alongside July and August. That doesn't mean full-day washouts every time, but brief heavy showers and lightning delays are common in the afternoons. Morning rounds significantly reduce your exposure to the worst of it.
At an average high of 84°F and a low of 69°F, May is warm but not yet at peak Houston summer intensity — June's average high jumps to 89°F. The real challenge isn't the temperature alone but the combination of heat and Gulf Coast humidity, which makes the heat index feel higher than the thermometer reads. Early tee times and proper hydration make May rounds manageable.
