Best Time to Visit Port Aransas & Cinnamon Shore
A month-by-month guide to weather, Gulf water temperature, rainfall, crowds, pricing, and the festivals worth planning a trip around — from the team behind Beached Inn at Cinnamon Shore.
Short answer: the sweet spot is late April–early June (warm water, low crowds, shoulder pricing). Choose July–August for the warmest swimming, October–November for the calmest weather and birding, or December–February for the lowest prices and emptiest beaches.
When is the best time to visit Port Aransas?
The best time to visit Port Aransas is late April through early June — Gulf water has warmed into the upper 70s°F, air temperatures sit in the low-to-mid 80s, spring break crowds have cleared, and rates haven't yet climbed to peak summer pricing. For the warmest swimming, July and August deliver Gulf temperatures in the mid-80s°F. For the lowest prices and emptiest beaches, November through February — air still averages 70°F daytime highs and the dolphins, whooping cranes, and shorebirds peak in winter.

Frequently asked questions
What is the best time of year to visit Port Aransas?
May and October are the sweet spots. In May the Gulf reaches a swimmable 78°F, days are warm and long, and the worst of Spring Break is past. October pairs comfortable highs in the low 80s with warm water that's still around 78°F, light crowds after Labor Day, and excellent fishing. If you want peak summer energy and warmest water, June through early August. If you want quiet and value, September or January through early March.
What is the water temperature in Port Aransas by month?
Average Gulf surface temperature at the Bob Hall Pier station: January 60°F, February 60°F, March 65°F, April 71°F, May 78°F, June 83°F, July 85°F, August 86°F (the warmest of the year), September 84°F, October 78°F, November 70°F, December 63°F. Most swimmers consider 75°F+ comfortable, so May through October is the practical swim season.
What time of year has the least seaweed in Port Aransas?
Seaweed (sargassum) season runs roughly April through July, usually peaking in late spring and early summer, so the cleanest sand is generally late fall through early spring. It's seasonal and patchy, and the water stays fine for swimming even when it's around. For the full month-by-month picture and how to check conditions before you go, see seaweed season in Port Aransas.
Should I stay in Port Aransas or on Mustang Island?
It's a bit of a trick question — Port Aransas is a town on the north end of Mustang Island, so they're the same island, not rival destinations. The real choice is between the lively town of Port A and the quieter condo-and-state-park stretch down the island. For a full breakdown of the geography and which area fits your trip, see Mustang Island vs Port Aransas. Weighing a nearby mainland town instead? See Port Aransas vs Rockport.
When is hurricane season at Cinnamon Shore?
Atlantic hurricane season runs June 1 through November 30, with peak risk for the Texas coast in August through October. The vast majority of weeks during the season are uneventful and the weather is excellent. If you're booking for August through October, watch the National Hurricane Center forecasts in the days before your trip and confirm your reservation's cancellation policy.
When is Spring Break in Port Aransas?
Texas Spring Break typically falls in the second and third weeks of March, with a smaller wave the first week. Port Aransas is one of the most popular Spring Break destinations in Texas, so rentals at Cinnamon Shore book out months in advance for these weeks and pricing peaks for the year.
When is the cheapest time to stay at Cinnamon Shore?
January through early March (excluding holiday weeks) and the weeks immediately after Labor Day in September are typically the lowest-priced. Early December before the Christmas spike is also a value window. Expect to pay roughly half of peak Spring Break or July 4th rates.
What's the weather like in Port Aransas in [month]?
Port Aransas has a humid subtropical coastal climate. Winter (Dec–Feb) averages highs in the mid-60s with lows around 50°F. Spring (Mar–May) climbs from the 70s into the mid-80s. Summer (Jun–Aug) sits in the upper 80s to low 90s with 80°F+ Gulf water. Fall (Sep–Nov) cools from the upper 80s back to the low 70s. Sea breezes keep coastal temps a few degrees milder than inland Texas year-round.
Are there jellyfish in the water at Port Aransas?
Risk is highest from late spring through early fall, with Portuguese man-of-war most often blown ashore on southeast winds in spring (April–May) and fall (September–October). Always check the beach flag — purple means dangerous marine life is present. Winter and early spring are essentially jellyfish-free.
When is the best month for fishing in Port Aransas?
September and October are local favorites — the Gulf is still warm, summer crowds have left, redfish run the surf and bays, and offshore fishing is at its best. Spring (April–May) is also excellent for trout and redfish. The Deep Sea Roundup tournament in early July is the biggest event on the calendar.
