Weather in Tampa in May

Shoulder season. May is shoulder season in Tampa — cheaper, quieter, and a genuine gamble. Highs average 30.5 °C, lows 21.5 °C, and rain falls on 12 days — nothing in the month is working against you.

May ranks 8 of 12 in Tampa: past the worst of the year but short of November, which is the month to book if the dates are open.

Rain on 12 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 30.5 °C days and 21.5 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 20 days top 30 °C, making the heat continuous rather than occasional. Across the twenty years measured, the hottest May day reached 35.8 °C and the coldest night fell to 14.4 °C, and the wettest single day dropped 51 mm — roughly 57% of the month's rain in one day.

May is moderately variable: 13 mm in the driest year against 256 mm in the wettest, around an average of 89 mm. Roughly two Mays in three land near that average, and the third does something else entirely.

Wind is light at 9.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 69%.

How May sits in the year

Temperatures hold steady either side: 27.7 °C in April, 30.5 here, 30.8 in June. Nothing about the timing within the month matters much. Rain is the thing that moves: June brings 13 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in May

May is at or near the longest days of Tampa's year: 13.5 hours of daylight, gaining 0.6 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

Despite being inland, the year stays fairly even: 19.7 °C between the year's warmest afternoons and coldest nights.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

May in Tampa versus nearby

If Tampa is one option among several, the nearby comparison is worth making. Cape Coral is close enough to be a coin toss — within a degree on temperature, 3 days more rain. Jacksonville is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: May is a compromise. November is 28 points better and is what Tampa is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
