kingdom67 Posted March 13, 2018 Report Share Posted March 13, 2018 Due to the north air currents, Miami may rarely have freezing temperatures. These little details do not mean that Miami Nin is not in a tropical latitude. There are no mountains in the north(mountains, himalayas like). I'm talking about plains and plateaus, too much space. Maybe if it were mountains, the cold winds from distant parts of the country would not have affected Miami. In Miami, coconuts are not dying. These details are insignificant, already a very small difference. Coconuts living in Maldives and coconuts living in miami have the same qualities and qualities.

Interesting you mention tropical Tampico, not only is it further south than Miami and below the Tropic of Cancer, it’s January temperatures are actually a little cooler than Miami. Yet there is this fixation out there to try and disprove Miami’s tropicalness. I fail to understand all this debate, of course Miami has a tropical climate. That’s not to say that all tropical climates are created equal or that there aren’t tropical locations that are significantly warmer than Miami/south Florida. 2 Corpus Christi, TX, near salt water, zone 9b/10a!

Dave-Vero Posted March 20, 2018 Report Share Posted March 20, 2018 One of the problems of the Miami area is that even the Homestead agricultural area can get cold on nights with extremely dry and cool air, thanks to radiative cooling. The immediate coast, with warm Gulf Stream water close by, is more protected, so the Keys and Atlantic shoreline harbor some native plants that won't make it just a bit inland. There's a reason why Fairchild Tropical Botanic Garden has areas protected from cold by walls and such. Quite a few genuinely tropical plants won't survive Miami's cold spells without protection. 2 Fla. climate center: 100-119 days>85 F USDA 1990 hardiness zone 9B Current USDA hardiness zone 10a 4 km inland from Indian River; 27º N (equivalent to Brisbane) Central Orlando's urban heat island may be warmer than us Link to comment Share on other sites More sharing options...

But there are definitely two seasons there. I don't think that there are really seasons in the tropics, but I have never lived there so don't know for sure. It also doesn't get the higher temps of inland southeastern US in the summer-but its also overall warmer in the winter. The key part to remember is that the tropics never, never , never get frosts/freezes/snow.

NC_Palms Posted October 8, 2018 Report Share Posted October 8, 2018 (edited) When looking at forest cover, I consider the immediate coastlines of South Florida to be tropical. The coastal hammock system is dominated by tropical species, which is the northernmost limit for most tropical plants.

Epicuria Posted January 7, 2020 Report Share Posted January 7, 2020 (edited) South Florida is not equatorial, but definitely tropical according to all widely accepted definitions. There are no record low temperature thresholds set. For those living over there and lamenting how the lows might occasionally drop low enough to prevent some ultra-tropical flora from growing, I can assure you that any climate type has variations both in terms of temperatures and flora. For example, continental climates have rather big differences in how low you can expect the temperatures to plummet in the winter. Does it become an entirely different climate type? No. Cold-winter subtype perhaps? Yes. We don't even have to look at the most dramatically contrasting examples to see how subtle differences affect the flora. Several temperate species will stop growing in Eastern Europe after you move just a little bit farther inland towards the huge Eurasian landmass, even though the winter lows may only be a few degrees lower than in coastal areas. This does not mean that you have transitioned to a different climate type. Majority of the vegetation remains the same. A tropical climate does not need to include ALL tropical flora, just like any other climate type does not need to include ALL flora which is found growing in some other areas which are classified as the same. In nature every transition is gradual, but climate classifications could not exist if there were no defined limits for a specific climate type, which includes a pre-set temperature variation. In the case of tropical climates at least 18C every month of the year is the definition, and in the case of continental climates you're looking at less than 0C in the coldest months of the year. Having driven around much of Southern and Central Florida, it is also quite striking how well Köppen's 18C coldest month classification seems to correspond to the predominant native vegetation, which looks tropical to the south of the isotherm. Again, some ultra-tropical species being missing does not define anything else but perhaps an equatorial climate, which is not the debate here.

greysrigging Posted August 25, 2020 Report Share Posted August 25, 2020 (edited) Chiming in on the topic half a world and a full hemisphere away from the subject city, going purely on climate data, Miami is definitely a 'tropical' location, despite being outside of the Tropical Zones as delineated by the Tropic of Cancer and Tropic of Capricorn. Similar temp averages to equivalent Southern Hemisphere sites on the Queensland and Western Australian coasts with the same or near same latitudes, actually a bit warmer for maxim average temps summer and winter. The minimums are substantially warmer all year round. I would not give too much credence to extreme historical lows....even coastal towns in tropical Queensland have recorded below 32f historically. Most Aussie regard the Queensland coasts north from say Noosa ( lat 26.4*S ) and the WA coasts from about Carnarvon north ( 24.88*S ) as being 'tropical', although the WA tropical coasts are actually arid deserts with less than 9" of a rain a year at Carnarvon. Getting back to Miami climate data, I would be looking at 5th and 10th percentile, and 90 and 95 percentile of maximum and minimum temps, daily and monthly.... gives a solid indication of the frequency of extreme events statistically.

palmsOrl Posted August 26, 2020 Author Report Share Posted August 26, 2020 According to the Köppen definition of a tropical climate, all of South Florida has a climate that is truly tropical. The occurrence of rare or even occasional freezes or even frozen precipitation does not necessarily preclude an area's climate from being considered (truly) tropical. The "tropical" designation is simply based on the average temperature of the coldest month. If the average temperature of a location's coldest month is 18C (64.4F) or higher, then the climate is considered tropical (under the Köppen classification system). South Florida is right on the edge of being tropical due to its relatively high latitude and geographical location, which periodically allows cold fronts to bring intrusions of greatly modified cold Arctic air to the region. Nonetheless, the climate of South Florida is still tropical by the most commonly accepted definition. 2 Link to comment Share on other sites More sharing options...

Townsville 24.35c ( 75.8f ) No one ever considers Townsville to be not 'tropical" . In appearance , climatically, vegetation, lifestyle, architecture etc it is a quintessential North Queensland tropical city.. And even so far into the deep north, infusions of cold air sometimes affect the region....latest being back in May this year with sub 12c ( 53f ) maximums just inland of Townsville. 2 1 Link to comment Share on other sites More sharing options...

palmsOrl Posted August 27, 2020 Author Report Share Posted August 27, 2020 South Florida is truly tropical by the currently accepted definition. In addition, South Florida likely has millions (tropical trees are ubiquitous in much of South Florida) large, mature tropical trees and easily 90+% of the non-native flora of much of South Florida is tropical. In addition to the annual rainfall (and other factors for certain types of climates), it is the temperature averages, not the extremes that define a particular climate. The extremes can and do, however, dictate a region's flora and fauna, both native and that introduced by man. In theory, an area could have an extremely rare cold event about every hundred years where the temperature drops to 0F, but if the average temperature of the coldest month is 18C (64.4F) or higher, then the climate of that area is tropical. Who knows what the native vegetation would be composed of in such an area, as 0F would completely kill all tropical vegetation, roots and all. 2 Link to comment Share on other sites More sharing options...

In addition, South Florida likely has millions (tropical trees are ubiquitous in much of South Florida) large, mature tropical trees and easily 90+% of the non-native flora of much of South Florida is tropical. In addition to the annual rainfall (and other factors for certain types of climates), it is the temperature averages, not the extremes that define a particular climate. The extremes can and do, however, dictate a region's flora and fauna, both native and that introduced by man.

My question is, why are "natives" so commonly planted in South Florida when we can sport all kind of tropical flowering trees? I know some exotics have been disasterous for the state, but there are many tropical trees that would perform beautifully here....but we are reduced to the same trees in public and commercial plantings. When I see pictures of Hawaii or the Caribbean islands, they have such great diversity in plantings in public and commercial areas...but we have the ubiquitious live oaks ad nauseum. Even when we there are non-natives, they rarely stray from the Royal Poinciana (which I love). Even local nurseries don't see many tropical flowering trees....and if they do, they have them in very large sizes that require a truck to deliver and plant. I have planted my yard with all kinds of tropical trees and I have had to go to over 10 nursueries just to find what I have been looking for. I don't know if it's the nurseries to blame who mass produce certain varieites or if local govt dictates to them what to plant for purchases later on? I think it's such a waste that we landscape our area to make it look like north and central Florida when we are unique and different. We should showcase that, not simply try to look like the rest of the more temperate parts of the state. 2 2 Link to comment Share on other sites More sharing options...

Aceraceae Posted January 5, 2022 Report Share Posted January 5, 2022 Even with frost in north FL, miami beach can hardly get a low below 64 this month. 1 Link to comment Share on other sites More sharing options...
