Miami averages 250 days of sunshine per year. That single statistic sells more plane tickets and signed leases than any real estate brochure ever could. But here’s what the sunshine number doesn’t tell you: those other 115 days can deliver afternoon downpours that flood entire intersections in 20 minutes, humidity that fogs your sunglasses the moment you step outside, and the occasional hurricane that turns your Tuesday into a plywood-and-canned-goods emergency.
This miami weather guide is written by people who actually live here. Not travel bloggers passing through in February. We’ve sweated through August, watched waterspouts form off South Beach, and learned exactly which months make Miami feel like paradise and which ones test your patience.
Whether you’re planning a visit, considering a move, or just trying to figure out what to pack, here’s the honest breakdown of miami weather year round.
Understanding the miami climate starts with hard numbers. Miami sits at 25.7 degrees north latitude with the Atlantic Ocean to the east and the Everglades to the west, creating a true tropical monsoon climate (Am under the Koppen system). That geography drives everything.
| Month | Avg High (°F) | Avg Low (°F) | Rainfall (in) | Humidity (%) | Sunshine (hrs/day) |
|——-|—————|————–|—————|————–|———————|
| January | 77 | 62 | 1.9 | 72 | 7.6 |
| February | 78 | 63 | 2.1 | 71 | 8.2 |
| March | 80 | 66 | 2.6 | 70 | 9.0 |
| April | 83 | 69 | 3.4 | 69 | 9.5 |
| May | 87 | 74 | 5.5 | 74 | 9.3 |
| June | 89 | 77 | 9.7 | 76 | 8.9 |
| July | 91 | 78 | 6.1 | 75 | 9.6 |
| August | 91 | 78 | 8.6 | 76 | 9.1 |
| September | 89 | 77 | 9.8 | 77 | 8.2 |
| October | 86 | 74 | 6.3 | 75 | 7.8 |
| November | 82 | 69 | 3.3 | 73 | 7.5 |
| December | 78 | 64 | 2.0 | 72 | 7.3 |
A few things jump out from this data. September is the wettest month at 9.8 inches of rain, while January and December are the driest. The temperature range across the entire year is only about 14 degrees on the high end (77°F to 91°F), which means Miami never really gets cold. What changes dramatically is the rain and humidity.
Miami essentially operates as two different cities depending on which season you’re in. The split is clean: dry season runs from November through April, and wet season runs from May through October. This distinction matters more than any other weather fact in this guide.
Dry season is when Miami earns its reputation. Low humidity, daytime highs in the upper 70s to low 80s, and virtually no rain for weeks at a time. The sky turns a deeper blue. The ocean is calm. Your hair actually behaves.
This is when snowbirds arrive by the tens of thousands. Art Basel happens in December. The Miami Open tennis tournament fills Crandon Park in March. Restaurant patios stay packed until midnight. Hotel rates climb 40-60% above their summer lows.
For residents, dry season is the payoff. It’s why you endured August. Morning runs along the Venetian Causeway feel effortless. Your electric bill drops by $80-$120 per month because you can open windows instead of running the AC.
Carlos, a project manager who moved from Chicago in 2023, puts it simply: “My first dry season in Miami, I called my brother back in Chicago while he was scraping ice off his windshield. It was 78 degrees and I was eating lunch outside in a t-shirt. In January. That’s the moment I knew I was never going back.” Carlos says dry season also cut his energy bill from $240 in August down to $130 in February, a difference he reinvests in weekend trips to the Keys.
Wet season separates the visitors from the locals. Starting in mid-May, afternoon thunderstorms become a near-daily occurrence. These aren’t gentle drizzles. Miami’s wet season storms are dramatic, fast-moving downpours that can dump 2-3 inches of rain in under an hour, often accompanied by lightning that lights up the entire sky.
Here’s what surprises newcomers: the rain is predictable. Almost every storm hits between 2 p.m. and 5 p.m. Mornings are usually clear and hot. Locals plan around this. Beach in the morning, errands by noon, stay inside from 2 to 4, then back out for the evening. The miami rainy season is more of a scheduling challenge than a lifestyle disruption.
The humidity, however, is relentless. From June through September, stepping outside feels like walking into a warm, wet blanket. Your car AC needs 5-10 minutes to make the interior tolerable. Glasses fog instantly when you leave any air-conditioned building. Mold becomes a genuine household concern.
Average monthly rainfall during wet season: 7.7 inches. Compare that to 2.5 inches during dry season. That’s three times the water falling from the sky.
Hurricane season officially runs from June 1 through November 30, with peak activity between August and October. This is the part of the miami weather guide that matters most if you’re considering relocating.
First, some perspective. Miami-Dade County has been directly hit by a major hurricane (Category 3 or higher) only a handful of times in the past century. Hurricane Andrew in 1992 devastated Homestead and south Miami-Dade. Hurricane Irma in 2017 caused widespread damage across the county. Hurricane Ian in 2022 weakened before reaching Miami but still delivered tropical storm-force winds.
Most years, hurricane season passes without a direct hit. But “most years” isn’t a strategy. Here’s what practical preparation looks like.
Power outages after major storms can last 3-14 days depending on your area. FPL (Florida Power & Light) has invested heavily in grid hardening since Irma, burying more power lines and strengthening poles. But extended outages still happen, particularly in older neighborhoods with above-ground power lines.
A portable generator ($500-$1,200) is a worthwhile investment for homeowners. If you live in a condo or apartment, confirm whether your building has a backup generator for elevators and common areas.

The best time to visit miami depends entirely on what you’re optimizing for.
This is peak Miami. Warm days (78-83°F), low humidity, minimal rain, and ocean temperatures around 76-78°F. The tradeoff: highest hotel rates, crowded beaches, and 45-minute waits at popular restaurants. Spring break (mid-March) brings the biggest crowds.
Hotel rates drop 30-50% during this window. Yes, it’s hot (91°F highs), humid, and right in the heart of hurricane season. But if a tropical system isn’t threatening, the beaches are empty, the restaurants have tables, and the locals-only vibe is strong. Many Miami restaurants run special prix fixe menus during “Miami Spice” season (August-September), offering three-course meals at top restaurants for $35-$60.
Shoulder seasons give you decent weather without peak-season pricing. November sits right at the start of dry season with highs around 82°F. Early May brings warmer temps but the daily afternoon storms haven’t fully kicked in yet. You’ll save 20-30% on hotels compared to February-March.
Daniela, a fashion buyer who relocated from New York in 2024, learned this the hard way: “I brought my entire fall wardrobe when I moved here. Wool coats, leather boots, cashmere sweaters. I’ve worn the boots exactly twice, both times to a holiday party where I wanted to look like I hadn’t completely abandoned my New York identity. My closet is 80% cotton and linen now.” Daniela estimates she’s spent roughly $2,000 rebuilding a Miami-appropriate wardrobe over two years, a hidden relocation cost she hadn’t budgeted for, and something to factor into your overall cost of living in Miami calculations.
Weather isn’t just something you check in Miami. It shapes how the entire city operates.
Air conditioning runs 8-10 months per year. The average Miami household spends $190-$280 per month on electricity, with July through September being the peak. FPL rates have increased approximately 12% since 2023. Impact windows and a well-maintained AC unit (change filters monthly during summer) can cut your bill by 15-25%.
During dry season (December-March), many residents open windows and run fans instead of AC, dropping monthly electric bills to $100-$150. That seasonal swing of $80-$130 per month adds up to $500-$800 in annual savings.
Rain dramatically changes Miami driving conditions. The combination of flat terrain, poor drainage in certain areas, and drivers who forget how rain works creates dangerous conditions. I-95 and the Palmetto Expressway see accident rates increase 30-40% during heavy afternoon storms. Leave extra time during wet season, and avoid driving during the heaviest downpours (usually 3-4 p.m.).
Flooding is a real concern in low-lying areas. Parts of Miami Beach, Brickell, Shorecrest, and Little River experience tidal flooding during king tides (October-November) even without rain. The City of Miami Beach has invested over $500 million in raised roads and improved stormwater pumps, but flooding events still happen.
That 250-day sunshine statistic is real, but it needs context. “Sunshine” in Miami’s official count means the sun was visible for at least part of the day. During wet season, a typical day might start with blazing sunshine from 7 a.m. to 1 p.m., get hammered by thunderstorms from 2 to 4 p.m., then clear up for a gorgeous sunset. That counts as a sunshine day.
The practical reality: even during the rainiest months, mornings are almost always clear. If you’re a morning person, Miami delivers spectacular weather 330+ days per year. If you’re an afternoon person during wet season, you’ll need indoor backup plans roughly 4-5 days per week from June through September.
For people coming from consistently gray climates (Seattle, Portland, London), the psychological impact of Miami’s sunshine is significant. Seasonal Affective Disorder essentially doesn’t exist here. The light is different too. Brighter, sharper, more golden. It changes how buildings look, how food photographs, how your mood operates on a daily basis.

March offers the ideal combination for most visitors. Average highs reach 80°F with low humidity (70%), minimal rainfall (2.6 inches for the entire month), and ocean temperatures warm enough for comfortable swimming at 76°F. Hotel rates are high but not at their February peak, and spring break crowds thin out by the last week of the month.
Not every day, but close. From June through September, afternoon thunderstorms occur roughly 60-70% of days. These storms are intense but typically last only 30-60 minutes. Mornings are almost always clear and sunny. Most locals describe summer rain as a scheduling nuisance rather than a serious disruption, arriving predictably between 2 p.m. and 5 p.m. and clearing before dinner.
Most hurricane seasons pass without a direct hit to Miami-Dade County. The statistical probability of a major hurricane (Category 3+) making direct landfall in any given year is roughly 3-5%. However, the consequences when one does hit are severe enough that preparation is essential. Tropical storms and weaker hurricanes pass nearby more frequently, bringing heavy rain and wind gusts that can cause localized flooding and power outages lasting 1-3 days.
July and August highs average 91°F with heat index values regularly reaching 105-110°F. Outdoors, it’s genuinely uncomfortable from late morning to late afternoon. But Miami is engineered for heat. Every building, car, mall, and restaurant is aggressively air-conditioned. Most residents structure summer life around AC: morning outdoor time, midday inside, evening outdoor time. The ocean stays at 84-86°F in summer, making beach visits a primary cooling strategy. If you’ve lived through a Midwest or East Coast summer with 90°F+ heat and no ocean, Miami’s summer is comparable in temperature but with a built-in escape at the shoreline.
The miami climate isn’t something you endure. It’s something you learn to work with. Dry season rewards you with some of the best weather in the continental United States. Wet season teaches you patience and planning. Hurricane season demands respect and preparation.
After a year or two, the weather becomes less of a topic and more of a rhythm. You stop checking forecasts in February because you already know it’ll be perfect. You start checking them obsessively in September because you know what’s possible. You learn that the 3 p.m. thunderstorm is just Miami clearing its throat before a spectacular evening.
That’s the deal you make when you choose 250 days of sunshine. And for the roughly 64,000 people who move to Miami-Dade County every year, it’s a deal worth taking.
